This Cobalt serving dish might be used for a myriad of purposes. Butter dish, Cheese dish, candy dish or simply anything your imagination might decide on. We love just looking at it~! Honestly, our pictures don't do justice to the beauty of this piece. The bottom has a gorgeous star pattern stamped into inner portion of the lid and on the bottom of the dish.  The overall piece has got some real heft to it, not being overly heavy, but substantial.  We suppose that the technical name for this type of glass ware is pattern glass, but we just call it awesome-ly beautiful glass.  What do you think?
