[TheForge] soda blasting

[Dan Rathburn]

Terry
When I worked for a company that made packaging equipment we made 
hoppers for powders like soda and had internal agitators to keep the 
powders from caking that would most likely be needed for your soda 
plaster tank. Some of the powders would setup hard if the agitators 
stopped to long.
