Review: Tougher than plaster of Paris. - Brilliant, been trying to find a local supplier but to no avail. Cheaper to buy in bulk but shelf life dictates otherwise. Used for making pebbles to paint which is better than removing ones from our shrinking shorelines. Can remove from the mould in less than 15 minutes, makes really tough pebbles that can survive dropping unlike ordinary plaster of Paris. Will be buying again when this lot runs out.
Review: Best I've found so far. - Takes a little practice but I was getting 💯 sucess after a couple of tries. Excellent results, lovely detail.

## Questions & Answers

**Q: I have been using Jesmonite (100) and wondered if this is a suitable alternative? It’s cheaper so intrigued. I make trinket trays & plant plant pots**
A: The Crystacal R will not give as strong / durable casts as the Jesmoninte Powders, you can use the Crystacal with the Jesmonite AC100 liquid which would give better strength that the Crystacal & water, however, this would still not be as strong as the Jesmonite AC100 product.

**Q: What are the dimensions of the tub please? Wondering if it will fit in my storage cabinet. Thanks.**
A: Height 20cms, diameter 22 and a bit cms but with the sticky out bits of the handles 24cms.  Hope it fits.

**Q: How long does it last in a sealed jar.**
A: Months rather than years. I think I read somewhere 9 months. It’s an amazingly fine plaster. Avoid casting on hot days as it will start setting before you can pour and it will fail.

**Q: Can this be used for succulent plant pots and will this soak up water from soil like plaster of paris does**
A: Crystacal R is a type of plaster of paris, but is harder than basic plaster of paris. This means it is somewhat less absorbent. Plaster of Paris is not water proof and doesn't really like to come in contact with water, so it will break-down over time if continually in contact with water. Hope this helps!
