Wondermold Orange Slice Crushed Glass Trivet Hot Plate Circa 1960s

Here I have a vintage 1960s circa glass hot plate. From my research this was made by Wondermold. It is not marked. I believe this is from about the 1960s or so. It has a beautiful resin crushed glass in like orange slices. The hot plate is 6 3/4 inches in diameter. It stands 1 inch tall. The bottom side of it does have some rough spots, and I believe a chip along the rim. I have given many pictures of it so please check those out. If you have any questions please ask.
