Frankly, I wouldnt worry about it JUST because it is from Japan. If this is something you lay awake at night thinking about, you should test all of your ceramics. Lead glaze is NOT outlawed here in the United States. Not that I have ever done this, but there isnt anything stopping me from making a bowl with lead glaze and selling it. Everyone knows and I hope agrees. not to do it, even the Japanese.

Lead is used as a flux, to lower the firing point of the glaze. Its only a problem if underfired, and left with an acidic food inside, say overnight, which you then eat. The Japanese and Chinese were making pottery before the United States existed.

I know this, it doesnt mean they knew about lead poisoning before the US existed. Thanks for the other info.

A quick, easy test put a freshly cut lemon slice on the surface of the bowl for a few hours if it leaches out any color, something is a little fishy. I would still use it, just not let any food sit in it very long. Thats just me, though, and since Im already a potter and going to get all sorts of nasty diseases from my profession, mayhap Im a bit foolhardy. . .

On the up side, if you DO get lead poisoning, youll be real good looking for a while bright eyes, pale skin, red lips. The young women who painted the pots made in places like StokeonTrent regularly died from lead poisoning, but they sure did look pretty for a while. I dont mean recently, more like a few centuries ago.

If your bowl is high fire porcelain/stone ware you dont have worries, if it is low fire lusterware/earthenware, glazed in bright colors then,best test for lead.
