Where can I buy a Glaze Sprayer. I am in Australia, New South Wales, and would like to know of a distributor. I have just recently subscribed to Ceramics Monthly and most of the sales are only done in the USA. I am a bit dissapointed that they don't do international shipments. Can someone help please??

technically, you can use an automotive paint spray gun -- it doesn't have the ideal aperture size for large particles/glaze, but they definitely work if you sieve well and water down your glaze slightly. our studio has been using a $10 paint spray set a student bought at an auto parts store, and it's been in use for several years without any issues as long as it gets cleaned out each use. personally, i like to use the Critter spray gun. I can't imagine it will be that difficult to find a spray gun in Australia. If you can't find one, look for online vendor - they will ship international unless they don't accept money...

Thanks for your reply, I have thought about a spray gun, however, thought the glaze would clog the nozzle. Will give it a try, you do mean one without a compressor, don't you?

clogging the sprayer is a big concern when dealing with suspended minerals needing to go through a tiny hole Posted Image you will most likely have to do a combination of watering down, sieving multiple times, or even ball milling a glaze in order to avoid issues. not all glazes can be sprayed - like a glaze with larger granular particles in the recipe, like some ilmenite, borax, cornwall, pumice, etc etc.
yes, I mean the type you need an air compressor to run - either the siphon or gravity feed versions like below:

i have used an HVLP sprayer but never tried it with spraying glaze, only lacquer. it's possible that these might work, but not sure for glaze

there is also this type of airless sprayer that have a pump in the handle, not sure how these would work either

this is the Critter sprayer that i personally prefer. I found that materials didn't need to be watered down as much - such a simple design with a huge siphon aperture...it's basically a glorified atomizer. I like them because the design is stupidly simple, easy to clean, and doesn't have many parts to fail aside from maybe needing to replace the brass tip if a groove is worn into it (glaze materials are abrasive). Reservoir can also be changed out for pretty much any jar that has a mason-jar's mouth size/thread pattern. I use Best Foods Mayo jars since they are plastic and the lids seal very well for holding glaze when used just as a container. I'm sure this sprayer could be used as a media blaster if I wanted to...

I have anew HVLP compressor and spray gun and it is great. I did getto much coming out the first time I tried it. I will get the adjustment on the nozzle to be where I want it.
I also have used an EZsprayer that I got from Archie Bray. It is similar to the Critter. hassle free.
It needs about 25 pounds pressure on the compressor.

Marcia, good luck with your HVLP sprayer. I had one but found it very complicated to clean when changing colors. I have two EZ sprayers and like using them now that I filed down the tip so the spray goes out properly instead of gumming up. the problem I have is with their plastic bottles. I have about 20 of them and found that one shipment came in a box that was too small. the plastic was crushed down so that the threads were too far inside the neck of the bottle. one was even an oval. I have looked at two pottery supply houses and their bottles seem to be the same. and expensive for what you get. each of these 12 bottles leaks. I wish I could find a different supplier of bottles that would fit the threads on the EZ sprayer. does anyone know of a supply?

have never had to adjust a glaze to spray it except adding a little water. the glaze dries so quickly that handling is easy, no finger marks from dipping to try to cover. cleaning is simple, I just spray out some water from the bucket used for cleaning and change colors.
