I would like to make a beach scene pendant. My concept is to have a sandy look on the bottom (as it is worn) with blue sky above. I would add shell inclusions and a clear doming layer. Is it possible to divide the first pour in a rectangular pendant mold to get blue on one half and sand on the other? Can I pour one color and "dam" up the mold somehow, let it cure and then pour the other side?
Thanks so much,
