what size flask will 10 pounds fill?

Hello, 10 lbs of Petrobond can be compacted into a 6" x 6" x 6" box. Thank you!

Will this hold up to the temps of melted Silver? 1,763°F

Yes, I’ve melted silver and brass with it. It does char the sand so some of it is not reusable but it keeps its shape at high temps

would 10lbs be enough to cast the size of a hand?

Yeah. You don't need a very thick amount around the void if using a steel frame. For heavier metals like copper I would pack a little extra. It sucks together and insulates quite well.
