paint help needed!

[ex-grammargi983.livejournal.com]

i'm planning a mad tea party. i want to take old teapots from thrift stores and paint them wild colors/designs. any suggestions for what type of paint to use? i'm a little worried that waterbased paints will run if any tea is spilled. i don't need my guests drinking tempura or acryllic!

what about waterbased paint first, then use a clear coat of glaze? spray paint? or do you think oil based would be better? i don't want to spend a lot of money and the paint job only has to last one night.

thanks in advance!!
