Hello, I am wanting to use a silver bowl as a mold for a project in my ceramics class, but I want to make sure first that having clay in the bowl overnight to set won't damage the bowl in any way or have a negative affect on the clay. Im using reclaimed clay so its a mixture of a couple types of clay, I can find out what kinds if that matters. I hope this is an okay place to ask, I haven't used this forum before. I tried researching my question but all I found was Information on silver clay lol.
