rmerrell Posted December 4, 2011 Report Share Posted December 4, 2011 I am a beginning potter with lots to learn. I recently purchased an Iron Red glaze from Standard Ceramics but I have not been able to get it to fire to an iron red color. It is has always turned out a very dark, almost black, brown. My question is for any of you out there who have used this glaze with some success. How did you do it? Link to comment Share on other sites More sharing options...
bciskepottery Posted December 4, 2011 Report Share Posted December 4, 2011 I've not used that glaze. However, from your description, it might be the glaze application was on the thin side. Try a thicker glaze application. Make a couple of test tiles and apply glaze in various thicknesses and see which one looks best. I do use a commercial iron red from another source and they recommend firing to a "hot" cone 6. In looking at the Standard Ceramics website, it appears the glaze breaks to black on edges -- where it would be thinner. Also, the suggested specific gravity is 1.47 -- which is a bit thicker than other glazes. Iron reds also benefit from a slow cooling -- and some potters program in a hold during cooling to promote growth of the iron crystals. Link to comment Share on other sites More sharing options...
