10 Lb Petrobond Casting Sand Ultra-Fine (190 Mesh) Delft Clay Alternaitve Molding Clay for Die Casting Replicating Pouring Highly Detailed Gold Silver Copper Pewter Brass Aluminum Brass Bronze Jewelry

This was my second purchase from these folks and they've always done right by me. The weight is always spot on and shipping was fast. This brand works better than other brands I've tried and way way better than homemade green sand. If you need high detail in your castings then this is where it's at. Works very well for all metals . It packs down rock hard with little effort and hold it's shape very well while still allowing gasses from metals, foam, wax and PLA vapors to escape. Greensand just doesn't perform near as well. I just sieved this 10lb batch in with my previous 10lbs I bought over a year ago. After about 50 uses I add 10 drops per 10lbs of any weight motor oil, mineral oil, hydraulic fluid or baby oil to rejuvenate it. All casting sands are a Little pricey in my opinion, but you get what you pay for and I'm extremely happy with this brand and so are customers. I will never switch back to any other kind and I will be buying more as needed. Thanks again!

It's fine (as in the grit)- and seems to be able to get high detail. Not sure it's *enough* detail to be considered Ultra-Fine, but it could have been my materials that caused the imperfections, so can't fully blame the sand.

Sand works great but I will say to learn what you are doing first. Im having issues with the clay falling into the mold but that is a me issue not packing the sand enough. Expensive for sand but when it is used right it is a good quality casting.

Great stuff

Utilized this 190 mesh Petrobond sand for my first fully enclosed sand casting. Followed all the proper sand compacting techniques and used foot powder for separation purposes. It just worked. No big clumps that were not manageable. No large grains. No sifting needed. This is a zinc alloy. For smaller castings the 10lb bag will last a long time.

I like this product and it purchased it several times. I think it's pretty high quality. I think you get a good amount of sand for the price. For those just getting into casting or casting really intricate parts I mix this with some delft clay to get the consistency that I prefer.

As described

If you were looking into petrobond sand. It works exactly as intended

Exactly as I expected it to be

Shipped fast and received in good packaging and as expected.

Came in an air tight bag and then boxed. Can’t wait to use it

Very clumpy, difficult to use for fine detail castings.
