Fixing devit with powder -- lessons learned

- THIS IS BASED IN MY OWN EXPERIENCE - do your own testing!
I've seen a paid tutorial by a very well-known expert that uses and recommends crystal clear powder (BE 1401-0008) on his original firings -- first time a project goes into the kiln. But in my case when I was trying to FIX DEVIT (could this be the difference?), crystal clear powder gave me very frustrating results. I was doing the same thing I had always done. Was it me or the powder?
I turned to the awesome Bullseye Glass Community on Facebook, and the commentary from others I received there was not to use crystal clear, but instead just "plain" clear, BE 1101-0008. Here's the post: / 1076699992846684
I switched and it worked perfectly! Here's the original BE tip on this, too. (Which can be confusing because the recommended products featured on this page include crystal clear... so maybe both work?)

I think more testing is in order... I won’t give up on crystal clear but the clear worked in a snap.
Here are other details in the video
Other BE glass used: Peacock (1176); Clear 3 mm tekta
Firing schedules:
First full fuse:
300-1100-30
100-1225-90
600-1490-15
9999-900-90
100-600-0
Subsequent attempts to add powder and fix devit:
300-1225-30
600-1490-15
9999-900-90
100-600-0
Slump (unknown platter mold -- bought it used, no maker markings)
150-1200-60 (slow ramp just because I wanted to be conservative)
9999-900-120 (two hours, again, just being conservative)
100-600-0
Thankyou so much for this amazing video, I have struggled with Crystal clear, why sell something that doesn't do what it's name suggests? I've ruined so many pieces with that powder....THANK YOU AGAIN.X
I think there are some who still swear by it. I just swear ABOUT it.
Another great video, Jamison! I love that you take us through the entire process and show the problems you encounter along the way. We’ve all been there. It is helpful and strangely comforting to see someone else experience issues which ultimately lead to success. Keep up the good work and thanks for all you do!
I feel your pain, I did almost the exact same thing 15 years ago. Yes, my piece is still to this day sitting on the shelf waiting for me to sand it and re-fire it once again. I admire your pushing through it and getting it done. Maybe that will give me motivation to tackle my piece again. Nah, it can sit there for a while longer..... lol
😂
Awesome vid! Beautiful piece, well worth the journey. Thanks for sharing your problems and solutions. YOU ROCK!
Haven't fully watched this video myself yet, but I've just noticed that someone in a big glass group has asked about precisely this problem. I'll link you there in hopes that it help.
Thanks for all of these greatly informative videos and projects, Jamaison! I've been following you for a while now, and always love your posts.
I only use Bullseye crystal clear powder to correct a devit problem and have never had a problem. As Bullseye points out in one of its videos, if the power is laid down too thick, it can trap small bubbles and result in a cloudy appearance, that applies to both clear and crystal clear.
Beautiful piece and thanks for the info on the powder. I wanted to use crystal clear powder yesterday on a project and couldn't find it so used clear. Maybe that is a good thing.
I’ve not totally given up on crystal clear and will do some more testing. But on this particular project, switching to clear saved my sanity.
That’s absolutely gorgeous! I’d always tried using crystal clear and got the same results, but this never even occurred to me! Good lesson! Now I’m wondering if the same might be true about OGT icicle clear vs clear.
It’s funny, because there are others who swear crystal clear is just fine and that I was doing something wrong? 🤷🏻♂️ But I’ve heard from more like you who have also had frustrating experience...
I have a piece I recently made which came out with some davit. I used Bullseye's tech sheet refusing it with the 2 grains of clear powder. The davit is still there. I did NOT rough it up beforehand, but see that you have. I can take this piece to D&L to use their sandblaster to start with a fresh surface. But before I do that and spend a fair amount of $$, do you think I should try to rough up the surface as you did and then add the clear powder? I think in your video you said you used a 400 grit pad. Thanks for any help. I don't want to lose this piece. Did you fire polish or do a full fuse? My full fuse is at 1480 in my Skutt kiln. Thank you.
My firing schedules are in my video notes… I went to 1490 on those redo attempts. I liked trying to sand off the devit myself because I just thought that would help with more of a fresh start? Not sure if it really made a difference but at least I felt like I was accomplishing something. 🤷🏻♂️
Oh my gosh! This platter turned out perfect and of course, beautiful. Your client is going to be so happy! I hope some day to be as good at this as you are.
So, I'm wondering what is crystal clear powder good for?
🤷🏻♂️
Thanks for sharing! 🐢👍
Thanks for sharing
I just ran into an entire batch of pieces that formed a scum. I have sanded them with diamond block and was not sure what to do next. how much powder did you put on the surface?
A few grains thick. I linked to this in the video notes: www.bullseyeglass.com/methods-ideas/quicktip-use-bullseye-clear-powder-to-fix-surface-flaws.html
What firing schedule did you use after adding the clear powder?
This detail is in the video notes on TH-cam. If you are watching in the app on your phone, you probably just click the headline under the video. If on your computer, I think it’s usually in a gray box with “show more” under the video headline or try to click the headline itself. Thanks!!!
👏👏👏🙏
Great piece of art.
Thanks!
Hi Jamaison, that is just a beautiful piece! I have a similar piece that I will have to sand and redo. My question is - when you dust the powder over the piece, how thick do you dust? Is it just a very thin coating or is it thick enough so you can’t see the color beneath the dust? Thanks!
Kind of in between? I can see some color through. I think Bullseye says “3 grains of powder” or something like that! 😂
@@JamaisonSchuler - Thanks for the help!
Oh! Jamaison. After all your frustration. It turned out beautiful. Well done and thank you for showing
So happy to have watched this, I too have had this problem and thought crystal clear was the fix. A misnomer for sure!
Thank you Jameson, I so appreciate learning your process and taking us on your journey. Today I learned about clear vs. crystal clear powder. Point taken! Mahalo
I love it! What a beautiful piece it turned out to be! Thanks again for your wealth of information!
I wish the manufacturers of the molds would sell them with a template. Often times if they are not exactly square or rounded etc mine droop over the edge as well. It’s hard to cut them to fit exactly sometimes.
Nice platter, I love that color as well.
Great video, thanks for sharing. Glad it turned out well in the end.
I feel for you. Such a frustrating process sometimes
Thank you-- I had the same thing happen to me with Crystal clear powder-- I won't let that happen again... Thank you for taking the time to share your experiences to help fellow fusers.
Sorry that happened to you too!
Thanks!! Great info and nice lunch date😊
Spray A works well for me.
Interesting ..Do you use the spray A when needed or on all your projects with clear /crystal glass? I have only used it on float glass which I’ve been very pleased with the results
Thanks for another great video! I have had the same problem, thanks for giving us the scoop on how to fix it!
I’m not totally giving up on crystal clear and will try some more tests. But on this particular piece, the change to clear saved my sanity!
Thank you! This is exactly what I needed for the same issue. Do you sign your art in any way?
Hi there! I’m not totally giving up on crystal clear and will try some more tests. But on this particular piece, the change to clear saved my sanity! I have an inexpensive engraver pen I bought from Amazon which is enough to etch a subtle date and my initials (just like the video intro!).

Nice!
Stunning platter. Yes, my glass art teacher says to always use Bullseye Clear (not too thick) over all glass before it's put into a kiln for a full fuse to prevent devitrification. Sadly I forgot to do this this arvo in my home kiln so fingers crossed I don't have to do a fire polish to get rid of this annoying cloudiness. 😊🤞🐨🦘
