How to temper porcelain and Pyrex for steaming

Fill a large pot with 5-6 cups of cold water. Place a cake rack inside and stack the dishes to be tempered on the rack, making certain they are completely covered by the cold water. Cover the pot and bring the water to a boil. Let the water boil for 10 minutes, turn off the heat, and allow the pot to cool to room temperature. The dishes can now be placed in steamers without fer that they will crack.

Once tempered, the dishes will remain so for their lifetime. They need not be tempered again.
