Spraying glaze on pottery usually requires special tools such as an air compressor, spray gun, and if you are doing airbrushing you’ll need all the little do-dads that go along with it. If you take the simple route of a mouth sprayer, you can get random applications.
Sometimes I’m just a lazy potter, if it takes too much time, I’ll happily let it pass on by ;P Spraying is one of those adventures.
So, I was browsing through Amazon, for nothing in particular, and a product called Preval Spraying System popped up as a suggestion! It wasn’t intentionally made for ceramics, but it looked like it could work for spraying underglazes…and the setup looked pretty simple…which is something I’ve been thinking a lot about lately.
It basically is a can of compressed air and a jar. Since I had used compressed air in the 365 Cup Project, I knew this had huge potential to give the results I’ve been wanting to play with and would love to hear about your experiences with spraying glazes/underglazes 😀Â
I figured I’d give it the Tammy Jo test so added it to my cart and away we go!  HOPE YOU ENJOY!

What is the dilution ratio for slip/glaze? You looked like you only used an ounce or so????
Hi Jack! Thanks for your question. Here is a link to the PDF Preval has with their instructions on rations.
I’ve only used underglaze in my sprayer, but when looking at the ratio be about 3 to 2. It was thin, but what I was more worried about was the granuals that may be in the underglaze clogging up the works. Its trial and error, but I will be trying again soon as I’ve gotten some liquid slip I’d like to spray on mugs at the greenware stage.
