Spraying Glazes

[LinR]

Is there any way to make a glaze sprayer out of ordinary spray bottles (spot removers, water sprayers, etc)?  I understand that most of these have a bore which is too small to take the particulates of glaze.  But it also seems reasonable that there should be a similar item which would spray glaze.

I've never used one so can't say how they work but there are these things:

I tried using a horticultural sprayer upon advice that it would work, but had poor results. The way the spray tip is configured was the problem. I have one of the sprayers shown in the Bridges Pottery video, and it works okay with human power making large droplets and spatter, but works much better with air from an air compressor directed down the mouth tube. Much better atomization.

 

I use spray guns from Harbor Freight along with one of their air compressors. One can get the whole setup for just over a hundred dollars by watching the prices of each component and/or using the 20 & 25% coupons. And, you can inflate your car tires too!

I use a Badger airbrush as used by model makers, for sorting dilute underglazes & gaze on small pieces, or in small areas. Never blocks up, inexpensive, compact. It suspect wouldn't be so good for larger pieces as the bottles are only about 75ml capacity, but I haven't actually tried.

Thanks for these tips.  I have a very small working space and was hoping for something I could store easily.

If someone has a small compressor or even a larger compressor with a regulator consider this one.

For spraying Glazes the 0.8 mm tip is advised compared to the 0.35 tip that is more common on air brushes.  With the o.35 tip you end up thinning even enamels and laquers considerably to flow smoothly.  Most Glazes are thicker than these so the 0.8mm  tip would be advised.  I believe this is the largest tip they make for most airbrushes.

 

Dependent on the settings and thickness of the glaze you should be get anything from the splatter effect seen in the video to a very smooth fine spray that creates a fading effect from one color to another.  While i had not worked with spraying glazes I had used air brushes with other medea and will say for smooth transition between colors they are the only way to go.
