#50200 SELF HARDENING CLAY:
This is our air-dry clay or Self Hardening Clay. No Kiln/ No oven/ No firing is necessary! Our air-drying clay is a rich dark brown color. Air drying will produce a hard, durable surface. Pieces can be decorated with acrylic paints and may be coated with shellac for a glossy surface. This clay is for sculptural and decorative pieces and is not recommended for functional dinnerware. It is great for classrooms without a kiln.
Some usage tips:
You can have cracking if a thick piece
dries too quickly so cover drying pieces with plastic so that they dry
slowly.
and if the piece is stuck to a modeling
board, you want to release it from there and maybe put on a rack so that the
bottom dries too.
If part is drying quickly and part is
slowly then you will crack because the two areas are shrinking at different
rates...
this is with all clay set to
dry.
Drying time varies vastly depending on
the humidity of the air in the room, temperature etc. It is also greatly
affected by the thickness of the item.
If something is very thick, see if you can
hollow it out and or start on a form of some sort.
Paint with acrylics when dry.
keep the bags sealed with twist tie. Mist
a little water into the bag if needed.
