Hi, I've asked about this bowl on the ebay PGP board, and it was suggested that it might be Sklo, and that someone here may be able to help with identification. Thanks in advance for any assistance.
The bowl is about 5 inches tall and 9 inches wide. It is heavy, a little over 5 pounds, and good quality with a nice ring. The glass is a smoky brown color, and the pleated design reminds me of origami folded paper. Top edge and base edge are polished. The little triangles on the base edge have quite a bit of wear.
