    Stuff looks great

    I use for alge control in rain water barrles and swimming pool. Only takes a tiny amount to keep the water perfectly clear. Very fine grained powder, easy to grab a pinch when needed.

    Copper Sulphate to wheat paste

    I've read that copper sulphate added to home made wheat paste for bookbinding will discourage moths from eating the binding. But the source didn't say how much to add. I will probably make one-half cup at a time. Do you know how much I should add?
