                                        Special Precautions

WARNING!  Although the free silica content is < 2%, repeated and prolonged exposure to any dust can cause lung damage and this product is no exception. The hazards can be virtually eliminated by good housekeeping and following the rules below:

    1.Since the wet form of the clay is dustless, flood areas to be cleaned gently with water and either wet broom, squeegee, or wet vacuum the water away. Clean often.

    2. Aprons and towels should be changed frequently during the day since the clay dries on them and when they are used, they flex causing the clay to then become airborne.

    3. Keep clay and glaze mixing areas separate from the rest of the studio and provide good ventilation to the clay and glaze mixing areas.

    4. Institute a regular cleaning schedule for the rest of the studio areas so that shelves and ware boards are washed outside regularly. As part of this program, place clean mirror tile sections throughout your work areas and monitor them often to see how quickly they become dusty. If they are dusty within a few days, you need to improve your houskeeping.
