got some at Ikea on sale rack. different sizes and shades of brown glass shaped nearly egg shaped but more like floats but no holes in them. They are a beautiful swirly pattern....but only can tell whenthey are wet. When dry they have a frosted coating. Is there any way I can 'polish' them. I do not want to tumble them cause there are no rough edges. They came in a bag that was woven like a net.
