Cazuelas are kiln fired at 2000° and are brittle when new. They should be soaked in water for six hours prior to use for the first time. They must be immersed in water rather than filled with water as that can cause the glaze to craze. If you live in a very dry climate you may want to resoak occasionally.
Once their moisture content is restored, they can be used over direct flame (gas or electric range) on low to medium (high heat not recommended), in the oven, or in the microwave. Start them with the burner on low heat. When the rim is warm to the touch, you can turn the heat up.
They may be washed in the dishwasher if they are placed so the rims do not bang against another dish as this may cause chipping. The cazuelas are durable if given minimum care & not subjected to abrupt temperature changes.
