Thanks FM! I'll hafta start checking out suppliers here in east TX and see what kinda cost difference I'm looking at. The lower gel point for the glycerine would make it much easier to work with - I could leave a batch in the processor and not worry about things getting too thick to work with.

I also appreciate your input on the PVC stuff. My storage barrels are on the other side of the shop, so I'm running pipe from my drying/blending barrel to the storage drums I'm using. 3/4 inch PVC would be a LOT cheaper than black iron pipe!
