How much does clay weigh?
Although different clays have different densities a good estimate is 90 pounds
per cubic foot. Chavant also produces a lightweight sulfur free clay called
Y2 Klay (approximately 65pounds per cubic foot).
Can I mix different clays together?
Concerns with mixing different clays are color, reactions to rubber, hard/soft
areas and cohesion. A user may hit firm areas and then soft areas when moving
tools through the clay. Proceed with caution.
How do I smooth the surface?
Try water, Avon Skin-So-Soft, WD-40, Goof-Off, turpentine, lighter fluid
and multipurpose oil/wax solvents by brush or hand. Some of the new "citrus"
based cleaning fluids will work well.
Why is sulphur used in some of the clays?
Sulphur is an inexpensive, non-toxic, filler that enhances the surface texture
of the clay.
Why is sulphur removed from some of your clays?
Sulphur free formulas are generally easier to make silicone or urethane rubber
Odor Reduction for Clay
Heating some Chavant clays in clay warming devices, often required to soften
the material, can produce a distinct non-harmful odor. Many clients have
successfully reduced odor emissions from clay ovens by attaching activated
charcoal filters to an exhaust vent often found on ovens.
Activated Charcoal (aka Activated Carbon) Filters are available from various
manufacturers. Check the Thomas Register under Filters: Activated Carbon.
