Hi Tamara, I have a set of cupboard craft Japanese stoneware – the flower design being similar to this Statestone. It’s in pristine condition, I bought it for my daughters hope chest recently. Now I’m wondering whether it’s safe for her to use one day. Do you know anything about the Cupboard Craft Brown sugar design made in Japan?
Hi Lindy – with similar age and similar patterns from the same manufacturer, lead-levels are likely to be similar. Here’s how to send something in for testing if that is of interest:
