Hmmm, Well, this is just a guess, but I have seen very similar pieces before, just not in those colors. I think these are 1950 - 1970 US made, late depression era bowls. The color is "Stained" that is not in the glass, but fired on color, right?
There was a similar pattern called "Petal" but I've forgotten the maker. Start there and see if that helps you. You may find them in a clear iridescent color, so just look for shape instead.
