Terra Cotta slip powder was our second ceramic powder tested in our lab. It has OK damp strength, good green strength, and has interesting behavior in the kiln cycle.
SPS Redart Terracotta Slip – 1000 units
Powdered Sugar ———– 250 units
Maltodextrin ————- 250 units
If you can’t find Maltodextrin, then use Benefiber (it is no longer maltodextrin but rather a wheat dextrin).
We are like the nature of Terra Cotta as it changes color and strength depending on how high you fire it.
Terra Cotta test firings. Notice that there is more shrinkage and the color gets darker as temperature goes up.
