Babs Posted August 30, 2014 Report Share Posted August 30, 2014 I had a bucket of totally dried out glaze. I slaked it down then ssieved it. I was left with slurry of stuff which would not pass through the sieve. I seived, watered down a number of times and still no go. So I will test the glaze, minus the gritty stuff before use. the glaze recipe is below. Which component would give this problem. The fact that I did not use this glaze for years does make it non precious to me but I am just interested as I now do work that I could use bits of glaze to layer onto pieces so saving throwing out these part buckets. If there is an identifyable chemicla I'll just not waste time with them. De Boos Mushroom.

Marcia Selsor Posted August 30, 2014 Report Share Posted August 30, 2014 Take the stubborn particles and run them in a blender for a while and then try to sieve. You should be able to break it down again. Marcia Link to comment Share on other sites More sharing options...
Mark C. Posted August 30, 2014 Report Share Posted August 30, 2014 The cheap thrift store blenders are one of my favorite shop items. They work great for zinc and other stubborn materials like your glaze. Mark Link to comment Share on other sites More sharing options...
Wyndham Posted August 30, 2014 Report Share Posted August 30, 2014 You might also put the material in hot , almost boiling water to dissolve the soluble salts from the frit plus other stuff that may have formed. Wyndham Link to comment Share on other sites More sharing options...

Wyndham That's exactly what I was thinking- 3134 has a fair amount of soluble material that has probably formed the chunks. It won't blend well.
