At the MakerFaire in San Mateo, May 21-22
there was a booth selling colorful garlic graters.
I tested the glaze at home with a lead kit
(you can buy it at stores selling paint for about $ 6
for 2 test tubes). It tested positive = detected lead.
I've contacted the seller and suggest you do the same.
Don't rub your food on lead!
