Casting Keepsakes Luna Bean Alginate Molding Powder Refill for Hand Casting Kit - Non-Toxic, Fast Setting - 3 lb (1,350g) - Anniversaries, Birthdays, Family Activities, Couples

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.

Used this alginate to make molds for my infants feet and hands. Works like a charm and is easy to clean up. Try and get them while they are sleeping and they will never know what happened lol.

Follow the directions and it works great, it does dry extremely fast without warning

It was my first time working with alginate and I'm pretty happy with the results. This brand is easy to use as long as you follow the directions. Since I didn't have a scale or measuring cup on hand, I had to eye ball the measurement. To my surprise, it worked and came out pretty nicely. I really like the berry scent and the color changing feature as it allows me to know when to put my hand into the mixture. The only issue I had was that the mixture sets a bit faster than what was written on the packaging. Despite using ice cold water, the mixture started to turn solid before 5 minutes which leaves little room to mess around. I also had some issues with air bubbles but that might be a skill issue. Still a great product though.

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.

Used for Clone A Willy, worked well, easier to use because of the color change.

Update: The seller reached out to me to provide assistance with this product and due to their efforts of making sure I was taken care of, I increased my review to 3 stars. Having a seller behind their product is important to me. At first I thought this would be a great option to make a mold out of a body part. The reviews seemed amazing and the value showed promise. However, I attempted to make a mold about 5 times but came up with a bad mold everytime. I mixed it as the directions asked and thought I would be able to create a mold in under 10 minutes using warm water. However, nothing seemed to work, which could have been user error but it was one issue after another. From drying too fast before I could create the mold, to not holding its structure/falling apart, to not being able to remove the body part without destroying the mold. Overall, after 5 attempts it felt like a waste of money and time.

for 2-3 minute time I used 90 ish * F water, which is not very warm. Not sure the ratio, but It was a lot of power, have to mix well though. Enough for me to get 5-6 tries out of what I needed to make.
