When the French Gospel Singers came to Staunton, we had an Ice Cream Social for them. One of the women taught me how to make an ice bowl for the ice cream. Today, I finished two bowls for the Menu #18393 . For the first one, I used two glass bowls. You have to be careful about "warming" up the bowls to take them apart... (you don't want to shock and crack them). For the second ice bowl, I used two nesting stainless steel bowls. The inner bowl warped on the bottom when water that I added went between the two bowls. It forced the inner bowl up from the bottom. Ice is strong!
