Review: FAR Better than any cheaper plasters I've tried - After your sticker shock, just don't even think about trying wall plaster (yes, I did). Now-a-days it's so full of 'easy sand' and 'lighter than the other guy' additives that it just can't be used for any kind of molding that involves heat. Plaster-of-Paris has it's own tradeoffs you can read about elsewhere. Compared to either, this stuff requires about 1/4 the water while still being very pourable. Moreover it doesn't take on air bubbles unless you are VERY aggressive with the stirring. You don't want (or need) to use a high speed drill - use a variable speed and keep RPM rather low. It does set fairly quickly. You want to be done pouring and de-gassing your mold within 10 minutes of adding water but unless the object has a troublesome crevasse I rarely get more than a bubble or 2 during de-gassing and the surface itself never rises a bit (like some plasters do). Surface rise indicates fine bubbles that will never come out. So even if you don't have a vacuum chamber, very few products have any hope of giving results even close to this and if you have one (recommended) this should easily stack up to any similarly priced products. For planning purposes I wish they told you what volume to expect. I only used it twice so far and estimate I'll get somewhere around 50-55 cu.in from a 5 lb. bag. That's something short of 900cc or 30 fl. oz. My casting flask is 3"x4" and I expect to be able to fill it 3 times. 4 if I measure really carefully and don't need it completely full every time. You may not have time to scrape the dregs from your mixing bowl before setting prevents de-gassing so expect a little waste unless you are dexterous. Update. Since my molds are typically 3d prints, I've converted to metric. To calculate use: 5lbs = 2268g. You need1.37g of powder per cc of volume so my 70mm ID x 95mm high flask takes 365cc to fill times 1.37 = 500g powder. Water = powder x .39 or 195g. So all measurements are perfect and easy by knowing these 2 numbers. A 5lb bag yields 1658cc or 101.2 cubic inches.

This works better than any R&R I've used. I cast with Siraya Tech Blue, and have a 10 hour burnout. Primarily silver, but have used it with 10/14K Gold and Brass. It get very fine details.
