Want to spray unsieved glazes?

[Daniel Spruyt]

If you want to have speckled glazes where the specks are generated by particles in the glaze, you should not ball mill or sieve the glaze.
What if you want to spray these glazes anyway? The conventional spray gun will be clogged quickly!
Solution: the good old vaporizer !
Two tubes of about 1/4” at a right angle and compressed air of about 50-60 psi will do (you can even use your lungs! but you need a lot breath!)
I had an old pistol for inflating tires where the manometer was broken.
Indeed it still can be used. The attached pictures are self explanatory.
The tubes used cannot be clogged and the spray is excellent. See also the attached picture of a pot sprayed with a glaze containing rather coarse iron particles.

Wow ... thanks, exactly the information I was looking to find!

Hello! This is exactly what I was looking for! many thanks for this info. I'd like to ask if it was possible to attach a recipient for the glaze so you can move the spray gun freely. Could a small plastic base be attached to it? Thank you!!!

Yes, obviously this is more handy. I must say that this kind of adaptation is still in my mind, but so far I didn't make it. With some simple DIY skills you can use e.g. an empty jam jar, pierce the lid and with some simple plumbing accessories fix the gun on the lid.

Thanks Daniel. I wonder if this could also work for higher density glazes with iron filings, etc. I think glazes should have less water content so that the iron filings don't sink to the bottom. (Please excuse my English :-))

Hi, your English is as good as mine, it is also not my native language (Dutch or French)

The times I used my system, it was with relatively fine Iron filings. My glazes are often quite liquid (90 ml water for 100g dry glaze) and this works fine with the device. Of course, the stem of the device should not be too long ( not more than 10 cm I guess) and from time to time stir or shake the glaze recipient.

Good luck.
