Kenneth Poe was asking about copper sulfide:

>sulfide. So far I have run into a wall finding it.

Hardware stores carry a liquid septic tank root killer that is 99% copper
sulfate pentahydrate. I thought it might be interesting next pitfiring/raku

Warning: The label strongly discourages use as digestif, skin treatment or
aroma therapy. Probably not so hot in a glaze batch.

I would appreciate hearing about anybody else's experience with and/or
chemical understanding of this substance. Anybody?
