Rick Malmgren Letting Go
After 28 years of teaching at the college, I plan to retire in June. It is a powerful experience of consciously letting go, and looking ahead to adventures, renewal and cherishing the lines and spaces that come with change.

Can you tell me about the air extractor and filter? Is that a filter or just a grill?
It it a spray booth with a large airflow to draw the tiny air particles through the grill and out the vent. The rate of the airflow is important, and we checked it regularly.
@@rickmalmgren2368 Thanks for the reply. Do you know the air volume of air going through the extractor? And do you filter the air going outside or just let the overspray + air go outside?
@@markkeown9532the number of cubic feet per minute is specified by the spray booth. It needs to be fast enough to draw all of the glaze dust away. The metal grill that you see traps almost all of the glaze, and any small amount that makes it past the grill is exhausted to the outside.
Hello after spray did you put in the oven?
What are you using for a compressor? This looks to be exactly what we would need. A HVLP spray gun that can handle heavy ceramic glaze.
Super helpful. Thanks!
One big mistake made after you clean the gun put 1/2 cup of water in it and blow the gun out completely with clear water you'll thank me later
A good way to mask off the inside of a pot is to take a whole wad of sponges and pack them into the top of a pot that you want to mask off you can manipulate the sponges all around so they're bulging out it doesn't matter as long as they mask the inner surface of that pot you'll be good to go if it rubs some of the glaze off when you take the sponges off you can usually just rub your finger around and recoat the interior or if you have to use a brush and dab it here and there it works phenomenally. If you notice all kinds of overspray went inside the top of this pot in this video
Paper dust masks are totally 100% inadequate for spring glazes you have to be insane to wear a paper dust mask while spraying glazes I am not a very overly cautious person please make a note of that you should be wearing a respirator.
Ive been using these airguns for ceramic glazes for over 20 years. The harbor freight guns are more than adequate, just remember to wear a good mask , you DO NOT want to inhale airborne silica
This is awesome and it's so nice to learn the basics of maintenance and how to even understand the gun. I have seen on most glazes that the liquid (non-fired) form is atrociously toxic and stays in the food chain poisoning lots of wildlife. Is there something special that can be done for the rinsing process that captures the glaze for firing on material or at least safe disposal?
why not a waterwall
we learned to clean rinse and clean spray with water several times on highest "paintspray
Thank you… great instruction and tips 👍
Can I ask what size of compressor you use
Hello! what compressor do you use? Thanks!
Do you use any secondary filtration with the laguna baffle filter?
Hi Aaron, no, for the spray booth we only use the Laguna baffle filter. That worked well for us.
And what pressure should I install? In compressor? Thanks again.
Start with a low pressure - say 5-10 PSI then gradually increase it until you get a nice spray. Use the least pressure that you need.
@@Rickaacc thank you so much!
Hello for everyone. Thanks for the good video lesson. I'm a beginner in this method. Tell me please what is the best SG (specific gravity)for glaze? Thanks for your answer.
I use the same consistency of glaze that I use for dipping. Keep it simple. Try your normal consistency and adjust as needed.
@@Rickaacc Thanks!!!
Enjoyed the video. Have you had good luck spraying with brushing glazes. I assume I would Need to thin them. I like potters choice and celadon.
Hi Shane, I haven't used any brushing consistency glazes. I've only used glazes that I've mixed from scratch that are at a dipping consistency. I think you are right that you will need to thin them some. Before they would spray easily. I suggest that you also run them through a fairly fine sieve (screen) to remove any debris that might clog the gun. Good luck!
Hi, I have been searching the net like a mad man to find "the perfect gun" for glazes. Is it really so simple that "any" Gravity fed HVLP gun with a 2mm nozzle will do? Some professionals recommend a pressurized cup for high viscosity fluids. Do you have any comments on that? And thanks a lot for the video :)
Hi Kenneth, like you, I tend to be a very serious shopper. But in my experience it really has been pretty simple. The relatively inexpensive gravity fed spray gun from Harbor Freight has worked very well in my personal studio, and at the community college where I taught for almost 30 years. That is where I would start. I don't think you need to look any farther for now. Airbrushing or spraying lacquer on a car are much more demanding. Good luck!
Rick Malmgren Thanks a lot for your Quick reply Rick. Living in Denmark i don’t have access to buy stuff at Harbour Freight, as the freight and customs fees Will triple the cost of the gun, but I’ll stop looking at Devilbiss and similar guns because of your reply and your video 😊
@@BinaryClay Nice to hear back from you, and I'm honored to hear from you in Scandinavia. My family is Scandinavian by ancestry, and I lived in Stockholm, Sweden as a kid. I loved it, and would very much enjoy a trip back to Denmark, Sweden and Norway. Maybe I'll do that some day. Good luck with your work!
do sprayers work if tilted down or on its side? Thinking of spraying large bowls and platters. I seems it would be easier than trying to dip and much faster than painting on 3 coats
Yes. You can tilt the gun down and sideways a little bit. I use it for spraying bowls and vases all the time. Good luck.
Cool video I use to spray 2 part epoxy on Entergy electric transformers, and we would have to finish the job or the hoses would freeze up. It made you keep in mind not to mix to much or you will miss out on lunch.😂
I have been looking at spray guns and compressors lately. I checked out this spray gun, but it looks so cheap. If you were getting one for yourself, is there a different spray gun you would recommend? It is hard looking at them to tell what is a better quality. This is a great video, explaining the cleaning and also the best way to spray. Thank you for taking the time to educate us!
i want to know.. if i can use hand spray.. just normal spray.. if i dont have this one
Wonderful video! Is there any special way to prepare the glazes aside from straining them. Would it be "dipping glaze" consistency or thinner?
Thanks! Glad you like the video. Yes, just strain dipping consistency glazes. That works well. Try different air pressures and flow rates to find what works best.
Hello...Im having hard time what the same gun, how Many psi do i have to use?? Thanks
we generally use 15-25 lbs. of pressure.
fantastic!
oooo thank you for this, it has been a great help, I've been thinking of buying a spray gun for glazing, this has been so much help.
Thanks for your note Ian, and good luck with your glaze spraying!
My daughter and make pottery and ceramics in our garagio (studio in the garage). I played with airbrushing a million years ago, but just got into handbuilding in the past 18 months. I read about spraying glaze, but this is the first time I've watched a video. Because we are essentially working out of our home, and we don't have room for huge buckets of glaze, we use all commercial glazes: Mayco, Amaco, Coyote. It seems to me those glazes are much thicker than the glaze you used in the spray gun. Would you recommend using commercial glazes, and if so, should I thin them out? Thanks for sharing this with us.
Yes, I would recommend using a glaze the consistency that you would use to dip the glaze. We use a hydrometer reading of about 50 to measure the specific gravity. Glazes that are of a brushing consistency would probably be too thick.
What psi are you spraying with; on the gauge on the gun?
We use about 30psi.
Which HVLP gun are you using?
It is from Harbor Freight 20oz. Gravity Feed Spray gun.
