Caring for Cookware and Foodware
Although Stoneware is very durable, here are some tips on how to care for your stoneware to ensure your favorite pieces last as long as possible.
NEVER PUT STONEWARE ON THE RANGE TOP! It is stoneware, not pyrex or corningware, and direct heat will kill it. Alas, modern corningware can’t go on the range top either, it too is now made of stoneware. (Hang onto those old corningware pieces!)
GENERAL CARE GUIDELINES:
Stoneware can go right into the dishwasher. Of course, you can also wash it by hand. Stuck-on food particles usually release easily, and a soaking in hot water will release even the most stubborn spots. Avoid abrasive pads and powders, as they will scratch and dull the glazes.
THERMAL SHOCK AND STRESS CRACKS:
The molecules in stoneware expand and contract when heated and cooled. If a piece is heated or cooled too rapidly, a crack can form, usually at a point of stress such as where walls meet bottoms. Potters do try to design pieces to minimize this, but it can still happen. Take care to heat and cool your piece as slowly as possible. Never put a hot piece on an icy counter and never plunge a cold piece into scalding hot water.
SURFACE CRAZING:
Sometimes glazes develop a web of fine surface cracks. Some glazes are more prone to this than others, and sometimes potters purposely use glazes which craze as it can be attractive on a decorative piece. Repeated use with hot liquids can cause this as well. If it is very deep it may render a piece unsuitable for use with food.
CHIPPING AND BREAKAGE:
Stoneware is much more resistant to chipping than earthenware, but it can still chip and break if subjected to rough treatment. You can try to glue a decorative piece back together, but do not attempt to cook in a glued or cracked piece, as it will probably fall apart.
GREASE STAINS:
Surfaces covered in matte (non-shiny) glazes can absorb oils. Generally this type of glaze is not used on cookware, but a bowl or plate might have some areas of matte glazes. If possible, try not to put oily foods into these pieces. To remove oil stains, wash the piece in hot soapy water.
