Casting Keepsakes (1.4kg) - Create-A-Mould Alginate Moulding Powder Life Impression Material

Product just as described and works amazing for casting with the color changing powder that allows you to know when to cast is amazing

I just used this to cast my hand and it worked fantastically. I mixed a full 1 pound bag into 7 cups of 80 degree water. It turned pink right away. I stirred it quickly and almost didn't have time to get it into the casting box. Then I plunged my hand into it. After a few minutes it turned gray/white and I was able to wiggle my hand free. After 20 minutes I filled it with plaster of Paris. I let that sit for two hours and then removed the mold. It came off easily. The plaster of Paris cast has great detail. I will use this stuff again. Some hints: 1. I made a form to hold the casting by taping together cardboard to make a tube. Then I put a plastic supermarket bag inside of that. The alginate is pretty thick so it was not a problem. 2. I should have been more careful to position my hand in the middle of the form; the alginate was thin on one side. Still, it held up to the plaster casting. 3. One pound was just enough to do my big hand up to just beyond my wrist. 4. I oiled my hand and arm with vegetable oil. I think that was unnecessary. I don't think the alginate would have pulled out my hair. 5. Next time I will mix it in an even bigger bowl. Really big bowl. I might do it with a bit more water; the alginate will take longer to set. 6. When adding the plaster I banged the mold several times to release air bubbles, but there were still some big ones. I should have put in just a bit of plaster to begin with and rotated the mold to get air out of the ends of my fingers. 7. Demolding was done with a small paring knife. At one point I broke the casting because I was pulling too hard. I should have taken my time. In the end I used some dental picks to get out the last little bits of alginate. Overall this is great stuff and very easy to use. I highly recommend it.

Purchased this various times

This Luna Bean Alginate Molding Powder works really well for capturing detailed hand molds, and the final result comes out impressively realistic. The material is non-toxic and skin-safe, which is great for couples, families, or even pet paw prints. Just be prepared to work quickly, because once mixed, it starts setting fast. If you’re not familiar with the process, I’d recommend doing a test batch first to get the timing right. We screwed up our first time. Overall, it’s a high-quality molding powder that delivers amazing detail when used correctly.

Excellent for one time use. Does what I expected and worked well but must use, as many times as you can, within 24 hours. After that it begins to break down.
