I'm making a few items out of Hydrostone, and I want them done and dry as quickly as possible.
The TDS says, "The maximum temperature at which HYDRO-STONE Gypsum Cement casts are safe from calcination is 120 °F (49 °C).With substantial free water in the cast piece, higher drying temperatures can be used without difficulty". I am circulating air in a box using a hair dryer on low, which never gets above 120F. It works alright- faster than room temp curing, but still requires 6+ hours of heating.
Are there any techniques to drive this number down further?
