I see these little Glasbake handled bowls at thrift stores fairly often — usually in plain white milk glass, with slight variations in the shape of the handle. They are frequently referred to as chili bowls or soup bowls, but I think their size is better suited to ice cream. Either way, they were originally sold as “French Casseroles,” intended for individual baked sides.
I was thrilled to find this beautiful set of four colors, complete with original lids, on the Goodwill online auction site. I believe they were part of a “Patioware” set that included square serving tiles — don’t think I’ll ever find those. But the colors are so cheery, I hardly mind. These rank pretty high on my list of favorite pieces!
