Hello, I created a sculpture and I used Amaco's Palladium glaze. The piece had to be on stilts and if you know palladium it ran. Basically, it ran and crawled where the stilts were and I have 4 bare spots where the stilts were. I am looking at getting some paint to cover up those bare spots but I don't know what brand/color would look close to paladium. Does anyone know what kind of paint or nail polish I could use that would be close to this glaze? TIA I was thinking of just glazing it again but I do not want that to happen again.

Hello all, I have been recycling clay for many years now and I have come across an issue I have not seen an answer for. My recycled clay looks fine from the outside but when I cut a piece of it off the entire inside is black. There is a border of about 1/2" where the clay looks fine, but the inside is all black. When I use this clay it smells really bad. The clay itself is fine and it does not really affect the throwabliity of the clay and it fires fine. I also have a slop bucket and I try to put vinegar in the bucket but after a while it goes back to smelling badly. I am guessing I have to throughly mix the slop bucket with vinegar to eliminate the smell. I guess my question has to do with the first part of the clay being black on the inside, why does it only get black on the inside and how do I get rid of black part and the smell short of throwing it away? I also do not want to use bleach. Thanks
