This is a glass piece about 4.5 inches across, it kind of looks like a coaster, but would be a bit tippy as it is some what convex, I would like to know what it is and where I could find more?

    It almost looks like the glass plate inside a microwave...maybe a mini microwave. I don't know why it would be convex, though, but it has the three little nubs for "feet" like microwave plates have.

    i have a candle dish that looks a lot like this. the 3 smaller dots, are those feet? you should be able to find them in any craft/big box store. (think target and k-mart)

    It could be a piece used in stained glass. I had a stained glass window made by an amazing artisan when I lived in Venice Italy that had 4" round pieces within it. They were swirled by hand and then outlined in lead to stay within the rest of the window. from @Gina Vivona

    I have no idea what it is, but it would be pretty in a plate holder sitting on a side table!

    After a little research I am thinking maybe fused glass?

    Not sure based on how large it is, but old canning jars used to have glass discs used as liners for the lids.
