Bill in OKC-
I would like to see the finish for the HDepot sand+bentonite- Looking to get a first pour done within Sept.... and I have almost all materials... and am trying to cast a wheel for a bandsaw as a prep/first project.
Group- I had posted a question for "Western Sodium Bentonite" earlier on another casting forum- and was directed to Wiki- Trying to do my due diligence before asking stupid questions so sorry if I missed it in the archives- but I was actually looking for prep info and if this item need any tweaks like the kitty litter or other clay forms- the bag says Nitrate free, Sodium 1% by weight... so I dont know if I need to pre-wash this stuff to remove anything or use it straight. Its sold as pond liner and I think its a decent buy- less than 20 bucks a bag (50 lbs per bag).
Any thoughts?

Randy, I've done castings with play sand. Chris Bailey uses it, and I used his. I've got the materials to make my own, just need to that round 'tuit.
Works well. I can post a pic of the items I've cast with it, if you'd like, or PM them to you. Decent but not spectacularly good surface finish.

It's a fine mesh, so the resultant sand has a pretty small, even particle size. Mixed with bentonite and water, it looks like it ought to do it. I just built the flask for the lathe bed casting, and haven't made a pattern for it yet. I'll post my results. Meanwhile, has anyone else tried play sand?
