You'll want to have the right ratio of powder to water based on your form/mold **Q: Can I use this for Lost Wax casting?** A: I can not positively answer yes or no, but from what I do know, I really think the answer would be, yes. I have not used it for that, but I have viewed someone cast a piece of metal jewelry at a festival. The mold looked just like the plaster ceramics molds I make from this plaster. I didn't ask him. You can only use the mold once as it is shattered when it is thrown into a bucket of water to quench the heat from casting. It would be imperative that you have the proper centrifugal cast equipment / set up to make sure the metal reaches the very bottom while still liquid. Good luck. **Q: Is this the same as hydro cal gypsum?** A: No. Hydrocal is a different mix. Same manufacturer though. **Q: Could this be used for pouring into a mold and then firing in a Kiln?** A: No this is not for a kiln firing. In a mold usage it is fine, but only to be air dried. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Plaster that’s sensitive to clay molds. *by S***R on January 26, 2026* The plaster was great!

Works very well kids did not complain about dust. Strong and durable when dry. ### ⭐⭐⭐⭐⭐ plaster craft products *by M***L on March 18, 2023* the 50lb bags came in 2 boxes of 25lbs each which made it easier for me to carry and work with. I make plaster craft items so the smaller bags are easier to handle. I have used this brand for many years and prefer it over others for its consistency in quality. ## Frequently Bought Together - AMACO Pottery Plaster, 50 lbs. - Edward Tools Paint and Mud Mixer for Drill - Mixes 1 to 3 Gallons - 15 3/4" Length - 5/16" Hex Shaft - Zinc Plated Steel - Reinforced Weld - Non Slip Hex Head - Easy Clean - Paint Mixer Attachment - QEP 7-1/2" x 5-1/2" Extra Large Grouting, Cleaning and Washing Sponge 3 Count (Pack of 1) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/48815949-amaco-pottery-plaster-50-lbs](https://www.desertcart.pt/products/48815949-amaco-pottery-plaster-50-lbs) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-05*
