Help identifying this shard!

This very frosted piece appears to be part of a bottle or jar bottom. There is a B in a circle (but font different from Brockway) and I think it says Tempera. I've been searching paint jars etc with no luck. Does anyone have any idea?

It's Brockway Glass "Temperglas". Their "B in a circle" trademark may not always look EXACTLY the same from one bottle to another.

Thx so much
