So thickening up the mix has definately helped with the overall strength of the castings. The problem I am having now is that I am having trouble getting the plaster to fill all the details and release some of the air pockets. I believe once I get the vibration table working this weekend that this will help. Also I might try thinning out the mix just a bit and seeing if it remains strong when demolding.
