The Joy of Metal Clay – Activated Carbon?

What is Activated Carbon? As promised, I decided to investigate for more information about carbons that are used in firing many base metal clays. I must say there isn’t a lot of understandable information. Activated is carbon that has been processed so that the carbon is more porous allowing a greater surface areas for the absorption of chemicals. The process used to activate carbon can be varied sometimes oxygen is used and in other cases a various of chemicals are used. The idea is to create a much more porous surface to allow better adsorption. There are several complicated ways …
