FIRE & ART GLASS SET OF 2 - 7” ROUND SAUCE BOWLS 1” DEEP

I do not have any knowledge of these bowls. I have done a search and have found nothing that is similar. No chips, no cracks or marks. These bowls are not perfectly round so I do not believe they were manufactured. The last 4 photos are one flaw I see, not a chip but just a tiny fraction where the yellow of the glass is off on front and back of bowl.
