Hello! This is my first post after reading so much fabulous and useful advice on these forums the last couple of years. I'm still a bit of a newbie potter and I've been selling for just over a year. So far I've been really pleased and no complaints or negative comments (exception: why don't you make in blue?) LOL. So I sent off a pair of mugs (Etsy sale) and the new owner is really happy with them, except that he just tried to microwave one to reheat his beverage, and he heard some "pinging" noises. He was alarmed and took the mug out and didn't try again; he's just wondering if I know what is going on. The details: I use Tuckers Pottery 6-50 cone 6 porcelain clay. I fire to cone 6 based on witness cones. (I use cone 7 in the kiln sitter to get there). Glaze: I am making my own glazes. The liner glaze in these mugs was an Assad Opalescent (basic high percentage frit based glaze with no added oxides). Outside was a floating blue glaze (from John Britt's book of Cone 6 glazes: Floating Blue #2) I've used both of these before and have been very happy, and I've personally have had no problems with anything in my home. Unfortunately, I have sold everything at this moment that has this exact glaze combo. Also not sure if a mug done the same isn't necessarily going to be a perfect "test" as glaze thicknesses, exact kiln position, exact top temp, etc may be slightly different? Any advice would be really appreciated! Mostly I'd like to know if in *your* opinion I should tell this buyer not to try to nuke these mugs? I know I've been a bit "reckless" in claiming my things are microwave safe and I'm sorry now I did without being more sure. I've read the forums about the astm standards and I plan to at least test more carefully than just a few things I have at home. Thanks in advance! Cheers, Lorraine.

I know that high fire stone ware is oven safe and dishwasher safe, but is it microwave safe?
