I know that these Cobalt Pyrex dishes are modern Pyrex items but they’re still pretty cool. This is a set of 4 6-ounce Pyrex Prepware Cobalt Dessert dishes for making / serving individual treats like ice cream, custards, baked apples or eggs. I think they also say you can use them as ingredient bowls when you’re cooking.

These vibrant oven-safe glass bowls are a deep clear cobalt blue in color. You could probably use them just for decorating as well. They also have other glass dishes like baking ware and pie plates in this Pyrex cobalt glass.
