My experiences is with small, shallow casting between 1/2 to 1 inch thick. The casting will remain wet for up to 24 hours, depending on room temperature, so be gentle in removing the mold. **Q: Anyone know the difference between this and the high strength 20 plaster made by the same company?** A: No **Q: Can low temperature metals (pewter) be cast in this plaster?** A: Probably not.... **Q: Can this be used for making molds for pouring porcelain? The molds would be placed in a kiln and fired at a high temperature for the porcelain to cure** A: I don't see why not? I made bats to dry out my recycled clay, so I haven't put them in the kiln, but it's just regular plaster used in ceramics as far as I can tell. You might want to test one before you commit to putting your work at risk. You could also buy plaster from a clay vendor whom you can ask to make sure it is kiln-worthy. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It hardend well *by A***T on 21 May 2018* ### ⭐⭐⭐⭐⭐ Great product *by K***S on 8 June 2021* ### ⭐⭐⭐⭐ It works *by C***1 on 20 August 2022* ## Frequently Bought Together - High Strength 20 Plaster for Scenery, Dioramas, Dentistry and Mold Casting 5 lb Pack Resealable Bag Great for Model Railroads & Gaming by Capital Ceramics - Practicon 7085610 Cavex ColorChange Alginate, 500 Gram --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/579617082-high-strength-20-plaster-for-scenery-dioramas-dentistry-and-mold](https://www.desertcart.jp/products/579617082-high-strength-20-plaster-for-scenery-dioramas-dentistry-and-mold) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-07*
