  1. I'm having a hard time finding a speckled clay without manganese. Anyone have any suggestions? I've searched the SDS sheets of Standard Ceramic, Laguna, Minnesota clay co and Amaco. The best I can tell is that Amaco may not use it in their 480M and 48M with grog but their SDS sheets don't seem to list all the ingredients so I'm skeptical.

Hydrated Aluminium Silicate 10-30% HYDROUS ALUMINIUM SILICATE 10-30% Fireclay 1
  2. Hi, I have been handbuilding with clay for a couple of years now. I bought a slab roller which is wonderful! Now I'm getting more into the science of glazing.

It has manganese in it and the glazes respond in unusual ways. I have a new piece to glaze which on the underside I practiced burnishing and lots of texture on the inside. My desire is to learn how to work with the beauty of the inherent qualitie
  3. Cheers! I thank you very much if anyone can consult. I don't know why in the black or red ceramic paste (which I have high temperature), my faldespatico base enamels do not cover this clay. The enamels come out with bubbles.., although in white clay they work well for me. I understand that black clays contain ox iron and manganese..
