[QUOTE="tyromeo55, post: 1461859, member: 1719"] UPDATE.. Well, with much effort I found the Bentonite here locally but had to buy a 100 pound bag of it of which I have only used about a half pound of. I made batches of greensand from blasting media (silica based) and filter sand. Both do pretty well. My only issue at the moment is the parting powder. It needs to repel moisture and the powdered limestone I am using just does an okay job. I have heard that black chalk box chalk made by Stanley works very well but it just sounds too messy. The moisture is not a problem at all unless you get the sand too wet. Id say that 1 cup of water for 2 1/2 gallons of sand is too much. Some people use ND 30w motor oil instead of the water because it does not steam so I might try that. Once I get good with Lead I'm going to give brass and Aluminum a go but I'll have to make a crucible to get the metal that hot If anyone wants to give it a try let me know an I'll give you some Bentonite which is the only hard thing to find [/QUOTE]
