Not to be a disagreeable type, but... technically this is not a rose bowl. Rose bowls are designs that have a folded or rolled in lip, so that they are more globular. From what I've read, rose bowls were designed to hold rose petals or potpourri. To be more agreeable... the vase in this post does look like it may be made for a frog. It is hard to say. I've seen vases like this with and without frogs. The glass looks familiar, but I can't place it.
