    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?

    Copper Sulfate

    Our water fountain has been green for years. Even when we bleached it. In less than eight hours of using two tablespoons of copper sulfate and we had clear water, and all of the moss and green slime were cleared sway.
