- Does sunlight really remove the color from Purpleheart? That's what I have read many times so I wanted to check it out for myself. This is a very quick look at what I found. I hope it's helpful to some!

Well, that proved wrong what I also thought about sunlight! Thanks Gord!
Take care, Dave
I'm happy if it was helpful, Dave. Thanks for watching!
Well what do you know? You learn something every day. Many thanks for this Gord. Hope things are OK with you all mate.
My pleasure, Stephen. I'm happy to help when I can. Thanks for watching!!
I knew the Purpleheart would lose the purple color, but I didn't know it could be restored. I heard that lacquer would preserve the color.
I know what you mean, Carol. I had read that sunlight would take the colour out of purple heart and also that it would replenish the color. That’s why I did this little experiment just to see what would really happen. I have not heard anything substantial about lacquer preserving the color. I guess that might be another experiment for me to try one of these days. Thank you for your input, my friend. Thanks for watching!
I have heard it said before as well, but when I've put purple heart in the sun, it really enhanced the colour for me. I've got one that was turned as a light pull and have not seen much sun and is now a brownish colour. I will experiment with that and pop it outside some point.
Thanks for sharing.
I hope it will return it to its original purple, John. Thanks for watching!
I think it’s the heat behind the window of a south facing window that gained the purple colour. My reason for saying this is if you get a heat gun and warm the purple heart up carefully, don’t burn it, it will turn purple. You can warm it so the wood is hot to the touch, leave it over night and hey-presto it’s more purple the following day. Try it on a scrap piece first.
You may be right, Andy. Thanks for the input!
Very informative, thanks for sharing Gord
My pleasure, Brent. Thanks for watching!
Great idea Gord. I will try it.
Glad you liked the idea, Jack. 👍👍😃😃
Great tip Gord - thanks for sharing. Stay Safe pal - Regards Dennis
Thank you, Dennis. I appreciate that, buddy. Thanks for watching!

I always thought the sun would fade colors. But in this instance, it didn't. I guess you can teach an old dog like me new tricks!! Great one, Gord!!!
I had a piece of purple heart a year or so ago that was cupped like the piece you sawed in half. I put the piece of wood in a steam chamber that I made for bending wood and let it soak for a while in steam, then i put it on a flat surface and then weighed it down under some plywood. It straightened out quite a bit. It was, not perfect but good enough where the joiner & drum sander would take out the rest of the cupping with minimal wood removal.
I guess we all still have time to learn a few things, John. Thanks for watching!
Cool, Gord! I've been told that oxygen makes it turn brown or grey. There is one way to make purpleheart colorfast, but it turns it a cranberry color. Wipe it with diluted HCL or Muriatic acid, then neutralize the acid.
Thank you for the input, Billy. It looks like I have quite a few things to try from all of the ideas given by the viewers. Thanks for watching! 😃😃😃
And yet another great video full of good information 👍😎
Thank you, Luie. Much appreciated, my friend. Thanks for watching! 😃😃😃👍👍
I will do that!
👍👍
Great video Gord! Thanks for sharing! Take care and GOD BLESS 🙏!
Thank you, Stephen. Much appreciated. Thanks for watching! 👍👍😃
I don't know either. Fresh cut is brown, then after a while the color can come back. No idea if the color will last. Take care Gord.
Thank you, Glen. Stay well, buddy!

I used a piece last week's video that was leaning in a rack. The side without exposure to light was brown while the other 3 sides were purple. Im confident light brings out the colour. Thanks for sharing Gord
Yes, I saw that video, Lewis. I was surprised by the coincidence. Take care, my friend.
I did the same thing with one of my bowls, turning it every night. Worked well. Adding a finish has seemed to keep the color
I’m glad you’re happy with it, Scott. So much to learn and so little time to do it. 🤔😳🤔 Thanks for watching!
Yup, I always heard it would make the Purpleheart turn to Brownheart, Gord. This is very interesting, thanks, buddy! 😊
Phil
Don’t you just hate it, Phil. Just when you start to think you know it all you come across something like this. 😂🤣😂🤣 Thanks for watching, buddy!
…..Gord
@@GordonRock1 Well, now I REALLY know it all, Gord! LOL!
😃😃👍👍😎😎😎
I’ve done the same with a bowl. Had it turned, sanded to perfection, and was starting to add the finish when I realized that my beautiful Purple Heart was an ugly gray. Took it outside and set it on the hood of the car for a few hours, flipped it over and let it sunbath on the other side for another few hours. It became the most beautiful purple bowl that you could imagine. Such a shame that someone dropped it and split it in 2.
Bottom line, Purple Heart responds positively to ultraviolet light.
Oh no! Having something you worked on so hard get damaged like that is a terrible shame, Doug. Sorry that happened to you! I appreciate the information, my friend. Thanks for watching!
…..Gord
Just made a bowl from purpleheart. Want to keep it from turning brown. Checked wikipedia for purpleheart info and found this:
"The trees are prized for their beautiful heartwood which, when cut, quickly turns from a light brown to a rich purple color. Exposure to ultraviolet (UV) light darkens the wood to a brown color with a slight hue of the original purple. This effect can be minimized with a finish containing a UV inhibitor. The dry timber is very hard, stiff, and dense with a specific gravity of 0.86 (860 kg/m3 or 54 lb/cu ft). Purpleheart is correspondingly difficult to work with. It is very durable and water-resistant."
So it looks as if the experts disagree with you. Wonder if they've ever tried your experiment. Looks like I'll have to try it myself to know what to believe.
Well, Alan, at least you didn't call me an expert. I'm definitely not an expert on anything. Just another guy who is passionate about woodturning and all the facets related to it. I don't expect anyone to take my meager attempts at experimenting with things like this as definitive proof. I just do these things for my own pleasure and like to share them with others. The only way to decide for yourself is to do your own experiment. I would be interested in knowing what you come up with, Alan. 😃😃👍👍
Happy turning,
.....Gord
Gord waow you come up with some great ideas and tips thanks have you any tips on how to keep the purple colour in Yew or does it always go brown and white 👍👍👍
I’m sorry, Gavin. I have never had occasion to turn Yew so I really don’t know very much about it. I would think that the same is true as it is of Purpleheart. I suppose the only way to know for sure is to try it. I wish you luck with it!
Take care,
…..Gord
I've used a heat gun to bring back the purple color in pen blanks. Works very well.
Thank you, Brent. I appreciate the input. 👍👍👍 Thanks for watching!
I really enjoy watching your videos. Keep up the good work!
Cool experiment and it does seem to work. I have heard that some wood change colour when put in sunlight. Cherry does turn colour as it ages. However I have never done any real tests on other woods to see if it does turn in sunlight..
Take care both of you and stay safe and well
Cheers
Harold
There sure seem to be a lot of different opinions on this, Harold. I’m not sure I will ever come up with the definitive answer. Might need to do some more experimenting. Stay well, my friend. Thanks for watching!
All the best,
…..Gord
I think if you warm the wood slightly with a low flame it also reinstates the colour,
Regards etc..
I guess that gives me another thing to try, Frederick. Thanks for the input. Much appreciated.
Hi Gord...I've heard that going over ph lightly with a torch will bring out the colour too...stay safe...press on 😎 Joe
I assume the keyword is “lightly”, Joe. Letting me get close to wood with a torch just seems like a bad idea. I might need to do some more experimenting, my friend. Thanks for watching!
…..Gord
Hi Gord, Great video and I have put purple Heart Pen Blanks in the sun for a few hours with great results.
I have also use a blow torch, on low, to rejuvenate the purple in the wood as well with great results.
I think any form of heat will normally get good results in varying times.
The only time I have failed to get the Purple to come back out was on my last video when the Purple Heart had been used for flood defence gates for over 200 years so were under water and I wasn't really hopeful of success in the first place but I had to try.
Great explanation Gord and I hope others will not give up on "Brown" Purple Heart as it is such am amazing wood to turn that can easily be brought back to its colourful life.
Take care my friend.
Cheers, Huw
I saw that 200 year old purple heart that you used for that pen, Huw. The fact that it was so old and that you did such a good job with it really made it beautiful in spite of the color. I wish we could all have results that spectacular, my friend. Thanks for watching!
All the best,
…..Gord
Placing Purpleheart in the oven at 325 degrees for 8-10 minutes (maybe longer depending on the size of the wood) will make the Purpleheart purple a deeper darker purple.
I don't think SWMBO would be amused if I was to put wood of any kind in her oven. In fact, I know she wouldn't!! So, that not a test I'm likely to ever perform, Cary. I'm not ready to test my mortality just yet!! Thanks for watching! 😃😃😃
Interesting video Gord, I have known for years that purpleheart would get its color back if exposed to sunlight as I had a friend do it, but I have never tried it because I do not use that much of the stuff because of the price! Thanks!
Cheers Al
Thank you, Al. Much appreciated, my friend. 👍👍😃
I turned my first Purpleheart platter about 9 months ago. Boy was I disappointed with the brownish color so, I did some homework. What I discovered was that UV light is what brings the purple color back, but the longer it is exposed to UV light, it will start to turn brown. I have found that mineral oil and bee’s wax helps bring out the purple.
Heat will also bring out the purple, but if you over heat it, it will become brittle. I did read that the purple color comes from the oil that is in the wood so, I took a small piece of Purpleheart and put in a baby food jar with some denatured alcohol and set out. After a couple of days the denatured alcohol started to turn purple.
I also read that if you apply a finish that has a UV inhibitor, the purple color will not fade.
So far I’ve turned two large platters 11”x2” and one smaller. Last week I used a 7”x2” blank to make a cigar ashtray. I love the color of Purpleheart, but boy is it hard.

Thank you for the information, Gunny. I really appreciate it. It looks like I need to do some more research on this but I sure do appreciate your help. 👍👍👍 Thanks for watching!
…..Gord
I have had experience with cherry, when I take it down from being stickerd to dry the places where the sticks were is almost white and te rest of the board is darker redish brown. I've same goes for cherry furniture, it will darken over time.
I appreciate the information, Dennis. I have a lot to learn about this so I do appreciate the input. Thanks for watching!
Great video Gord. I don't have any Purple Heart. So if possible it would be nice to know how long the purple color lasted on your boards before it reverts back to that chocolaty brown...Thanks, V
I will try to monitor the colour of the boards, Mike. I might try putting a number of boards in different rooms with different lighting to see what happens. Thanks for watching!
I always thought that sunlight would turn most colored wood brown. Interesting experiment you conducted. On a similar note someone (I don't remember who) told me you can preserve the purple color by wiping it with Armor All which is used to clean call finises and brighten tires. I never tried it but maybe you can expend your experiment to see if the color remains.
That was the impression I was under as well, Tom. Just when you start to think you know it all something like this comes along. 😃🤣😂 Thanks for watching, buddy!
Thanks for the info. Yes I was told the sunlight will dull purple heart. I know the truth now.
My pleasure, Dwight. 😃😃👍👍
Seems to me, Vinegar brings out the Purpleheart. Worth a try. Good shot - long term goes gray to silver.
That certainly does seem worth checking out, Martin. Thanks for the tip. I’ve had a lot of suggestions to try so I guess my experimenting is not finished. Thanks for watching!
Leave one in the window for six months or a year and see what happens.
When a purple heart log is first milled into lumber it is grayish or brown tinged with hints of purple. As the extractives react with light and air they begin to turn purple. Continued exposure will degrade the color to brown and eventually grayish. By sanding, you have exposed extractives which have yet to react with light and air which turns them purple - and will also degrade to brown and eventually gray. You should have put a piece in the window that had not been freshly milled, as a control subject, to see if it reacquired its purpleness.
Experiment with acetone which will pull extractives up to the surface available for the reaction. Unfortunately, this color is fleeting as well. 😞
Cheers,
-- Joe
That’s the best explanation I’ve heard yet, Joe. This certainly gives me a lot to think about, my friend. Thanks for your input. It is much appreciated, as always. Thanks for watching! 😃😃😃👍👍
…..Gord
Well Gord it does seem we have number of things in common. Today I learned 2 more.
One is I always heard that direct sunlight will turn Purple Heart brown. So all my turnings with Purple Heart are out of direct sunlight and they are still purple.
The other is I am also a bit color blind so maybe I do not even know what purple looks like! LOL
But I sure struggle with some browns and greens. Many a battle has started when I insist that no that is not GREEN! Well she ends up wining because I have not glue.
I wonder if having finish on the piece makes a difference. I do have a nice slab of 2" thick Purple Heart that started out 6 feet long and 1 foot wide. It was brown when I bought it at a garage sale and had no idea what kind of wood it was till I turned a piece. Then all the purple showed up nicely.
Great experiment my friend, now if we could get some sun light down here in Oregon I will try it.
Take care,
Gary
Gary, one thing I never argue with SWMBO about is color. She seems to be able to see 6,000 different shades of white. That’s just ridiculous! I don’t know what kind of finish you could put on a piece of Purple Heart to maintain the colour and still see the colour through the finish. I’m hoping to get answers to some of these questions from other viewers. Take care, my friend. Thanks for watching! 👍👍😃😃
…..Gord
I mostly use lacquer on Purple Heart.
I have one that sits on our old piano and the sun does not hit it.
Speaking of the old piano I hope this is the year I take it apart and use the wood for turnings LOL. No joke...you can not give away a upright piano built in 1904. And no I did not buy it new LOL
😂🤣😂🤣
Now only if I had some sunshine! ( soggy, wet spring here with too much rain and very overcast skies). Sigh!
Sounds to me like you might be a West Coast girl, Valerie. I have friends who live on Vancouver Island and as beautiful as it is in the summertime I don’t think I could stand the rest of the year there. Way too much rain and cloud for this prairie boy. I hope there is a lot of sunshine in your future, Valerie.
Take care,
…..Gord
@@GordonRock1 Directly south of Victoria, in the “sun belt”. Not our usual May weather this year. But we do grow great wood for turning!
Beautiful country, Valerie! Which side of the border are you on? You don’t have to answer if you’d rather not. I’m just curious.
@@GordonRock1 South side of the Strait of Juan de Fuca , nestled up in the foothills below Olympic National Park.
I’m in Vulcan I can get my south window to 120f already I know Red Deer is so much further north that you never really get summer but just food for thought LOL
You Southerners! Any excuse to show off, right! We actually had summer last year for about 20 minutes. It was a nice change. Enjoy your heat wave! 😎😎
Interesting experiment, Gord. I hadn't heard either way but my first instinct was that the sun would cause it to turn brow just like it makes other things fade. Who knows for sure besides you? I expected to see that little guy over there sunning himself (lol). Take care.
Bill
There seems to be some disagreement as to whether it is the light or the temperature that brings back the purple. I guess I may need to do some more experimenting, Bill. Take care of yourself, my friend.
…..Gord
I have little experience with purple heart wood however I watched a video which I believe was was thepapa1947 (Gary) who after turning a piece brought the color back with a heat gun.
Thank you for mentioning that, Tim. I appreciate it and will have to try to find that video. Thanks for watching!
@@GordonRock1 might want to give Gsry an email so he can tell you if I was right or wrong (it has been known to happen, both ways lol) and he might be able to point you to the video. Of course this was after he turned the wood which took away all the color.
Will exposure to an ultraviolet light do the same ????
I don’t know. I don’t have a UV light to test it with. Sorry!! Thanks for watching!
Try your uv light on honey suckle and see what happens!
I've wanted to try more than a pen in purpleheart, but haven't seen any around when I've been in stores. Might have to include it in an order I'm planning for fall.
So, maintaining the colour. I'm assuming it UV or some other quality of the light brings it back, I imagine any finish without UV blockers would allow the colour to return. Have you any information about purpleheart once it is a finished piece? I wonder if anyone has tried ferric oxide solution on it. Would it darken, or go black? Sound like I need to get my hands on a piece of purpleheart.
Thanks for the experiment, Gord.
Good questions, Jay. I wish I could answer them for you. Sounds like there might be an experiment in your future, as well. 😃😃
Take care,
…..Gord
So Gord, how can you lock the color in once you get it back? Seal with a build up surface finish? I always felt like the flame red in box elder, Manitoba maple, diminished in sun light? Curios? Stay well.
I don’t know what would lock the colour in, Dick. I have never had any luck with maintaining the colour. It always seems to turn brown or some other rather unattractive color. The colour in any exotic wood always seems to fade or change to some other less attractive color. I’m hoping someone else will have a comment on this fact.
Take care,
…..Gord
Heat will bring the color back as well
I think I may have to test that. Thanks for your input. I appreciate it very much.
Howdy Gord, been a long time since being able to get on and just surf for a while. That nice purple color draining out of a project is sure sad when first experienced! Here's a little experiment I did a few years ago with some cheap Ultra-Violet LED strips from Amazon. th-cam.com/video/DYxGaFJGqqE/w-d-xo.html Possible to purple the wood back up quickly by oxidizing it. As others have mentioned, time will continue to affect it so once there, you want a finish with a UV inhibitor. Good to see you're still Rocking it! And that your videography skills are an order of magnitude better than mine :) Take care!!
Hello Bill,
Wow, that is a lot of LEDs. Thanks for the link and the information. Much appreciated. Glad you stopped in for a visit. 😃👍 Thanks for watching!
Take care,
…..Gord
Lol I actually belonged to the central Alberta guild until I moved we just never met
That’s amazing, Ron. I can’t believe we never met! If you still come back to Central Alberta for visits please give me a call next time you’re up here. Maybe we can spend an afternoon in my shop.
I heard that machined surfaces exposed brown wood and that oxidation returned the purple hue. I recently turned a purpleheart bowl and the purple blank did end up brown. The bowl sat on my bench for a few weeks and it turned purple. What was most interesting was that the bowl had one coat of water based sealer and two coats of water based ployurethane. I would have expected the finish to block oxidation. Maybe it was light, mostly daylight LEDs but still.
That’s awesome, David. You must’ve been very pleased to have it turned purple for you. I appreciate the information, my friend. Thanks for watching!
You can't argue with the evidence. They weren't purple now they are.
Very succinct and well put, Judith. Thanks for watching!
U.K. doesn't see the big yellow thing much so can't comment! Oh fluff,fingers on autopilot!🤣🤣🤣🤣🤣🤣🤣🤣🤪
Oh come on, Alan. I heard you guys had summer last year for close to 20 minutes so stop complaining. 😃😃😎😎🤣😂
