What else can be done to achieve faster curing of the investment?
A heating cabinet can be constructed where flasks (molds) can be placed after the water of top of the flask has been removed. However, provision must be made to remove the moisture laden air in the cabinet by exhaust continuously. Feeding cooler air with less moisture and removing the moisture laden from within the cabinet and maintaining cabinet at about 82 to 85 degrees would appear to be the best answer.
