VINTAGE Artisanal Covered Casserole Dish

This off-white casserole has sparkling gold trim. It appears to be hand-glazed, and maybe even hand molded. On the bottom there is a signature and the date '78. Because I don't know anything about the materials or finishes, I am selling this item "for decorative use only," as I can't certify that it's food safe. It measure 12" across from handle to handle!
