so i've been digging around the internet for some, and brands i found were:
pebeo 150 or 160, found on www.dickblick.com. there's a line that you paint on, and a line of the same in marker form. you just bake them at 300* for 30 minutes. it's safe for glass, porcelain, and metal, so long as you can heat it. they have a special line for glass, also.
Vitrea glass paints.after reading more closely, they're the pebeo brand. they also have to bake about 40 minutes. (project here:

also, i found some stuff called Klenk's Epoxy that's supposed to be water and bacteria-proof and comes in 4 colors, but i haven't looked into it to much yet.
i hope that helps some other people who were also looking for food safe paints.
also, while i was looking, i saw that on the carol duvall show they used sculpey to make a faux glass plate, but didn't mention if that was food safe or not. i thought scupley was not food safe?
[edit]and, just in case someone would want to know, there's a brand of wood varnish that is food safe at www.calistawood.com
