Shannon, if you can find a black light, try it on your bowl. After I wrote the message to you yesterday, I thought about something else -- it may be vaseline glass with something in it that gives a different color. You can buy a little black light on eBay for a few dollars. They are not so good, but they will definitely light up vaseline, custard, and uranium glass. I have one of them and they work fine -- I can pick up the pale green of old American glass.
