Review: Plaster that’s sensitive to clay molds. - The plaster was great! Very strong, no are bubbles. And, it absorbs water well to use with clay.
Review: Fast drying and easy to use - First time every doing this but I needed to make a slab to recycle my giant bin of clay. I did this on my one hour lunch break and it even dried within that time frame. I’m gonna give it a few more days to dry before testing it out with my clay. I have high hopes. It arrived in 2 separate deliveries in 12.5 pound bags (50 pounds total). I actually enjoy that they are separately packaged. I used one bag in a tub of water to make my board. I didn’t use exact measurements or anything kinda just eyeballed it cuz that’s how I roll. It’s been a few hours and it’s pretty dry. I think it’s worth the endeavor!

## Features

- When mixed with water @ 70% water by weight, and allowed to slake for one minute, then mixed energetically till lump free, it will set up in 30 minutes.

## Questions & Answers

**Q: does it break easy? for example if I want to do trinket trays**
A: This is stronger than plaster of Paris. 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.

### ⭐⭐⭐⭐⭐ 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.
