Only food safe glazes are used in my functional work!
On occasion I am able to participate in Raku firings, the Raku pots that are produced include areas of porous un-glazed clay that is not water tight - so you should never eat off or drink from Raku-fired ceramics, these items are meant as decorative pieces only.
Except for items decorated with gold luster, everything I make is microwave safe. As with all ceramics and glass, however, take care to avoid drastic temperature changes (like plunging a hot mug in an ice bath) - the sudden thermal shock may cause the piece to crack.
Everything I make is dishwasher safe, but if your piece is decorated with gold-luster hand-washing with warm soapy water will prolong the longevity of the gold overglaze.
