I am having a terrible time mixing a dry glaze. I ordered a white dry satin glaze that should be fired to cone 5-6. I mixed 11oz of distilled water per pound of dry glaze (as recommended by the company that made the glaze), let sit overnight and sieved with an 80 mesh screen. Then when I was dipping pieces the glaze seemed a little too thick and was cracking as it dried, so I added water a little at a time until the cracking stopped. The specific gravity was in range and the viscosity seemed good. I let sit overnight again and the glaze is now super thick, like the consistency of yogurt. Do you know why this happened? Did I add to much water and somehow ruin the glaze? Is there a way to fix it? I contacted the maker of the glaze and they said to "just add more water" and that they did a test batch and it worked perfectly when adding the recommend amount of water. So, in my frustration I took 8oz of the glaze and added almost 8oz of water to it to get it thin enough to dip, and fired it and its crawling like crazy. What am I doing wrong here?
