## Questions & Answers

**Q: Is it safe to use for dental impressions for forensic analysis in a high school lab?**
A: I do not believe that this product is a dental grade alginate which is what you will need. Try this http://www.amazon.com/Hollywood-Impressions-Molding-Powder-Alginate/dp/B000KI6W5Y/ref=sr_1_1?ie=UTF8&qid=1398300899&sr=8-1&keywords=dental+impression+kit

**Q: How many whole adult hand casts could you make with one box?**
A: Most probably three or four possibly more, depending upon how closely the casting container is made and how far up the arm the casting is to be made. You have to be a bit careful of having the alginate too thin particularly at the edges where you transition from the casting to air. it can and will tear if it is too thin.  You might be able to make a dozen or so casting if you simply paint the alginate onto The hand and then reinforce the cast with plaster of paris. I've heard of this method, but, have not tried it.

**Q: I want to make a mold of 16 different 4 year old's hands.  How much of this stuff will I need if I'm using 1/2 gallon containers for each one?**
A: Well if your using 1/2 gallon containers. Your mixture rate is 1:1 . that is 1 cup alja safe 1 cup water. So you need to probably use for each cast 3 to 4 cups alja safe and 3 to 4 cups water. 16 casts you would probably need about 9 pounds of alja safe.

**Q: How much heat alija safe can tolerate when casting?**
A: If casting material reaches the boiling point of water, the moisture in the Alja Safe will convert to steam, causing bubbles in your casting.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Ignore the nay sayers. This product is easy and fun to use.
*by I***U on June 4, 2017*

Great product for making molds of any thing you want. Ive used it for making molds of different lure designs and they have all come out great.I see several reviews saying the product is crap and others saying do not buy it. All I can say is that your doing it WRONG! If you use warm water, you already screwed up. The water at 80 degrees actually feels slightly cold to the touch. The warmer the water, the faster it sets up. 50/50 mixing ratio is a bit off for my liking but that's my opinion. I like to add an extra ounce or so of water to thin it down a bit which produces excellent details and pouring ability. Ive done several molds from this package including hands, feet and a face and still have some left over to play with.The trick is to find a water proof container just slightly larger than what your casting so you use less product.I use old lures melted down in an old microwave for my lures. This product hold up very well. If you cast a larger piece, you will see steaming and bubbling of the melted lures but in the end, when its cool, you still get excellent results and very few bubbles.Please, do not be put off by the negative reviews. Not every one can read and comprehend the instructions. Some people do not even try something small to see how the product works before trying the actual project. Ive yet to screw up one single project.

good stuff!!

### ⭐⭐⭐⭐⭐ It Works
*by D***N on September 17, 2025*

Worked perfectly as expected, I need a little more practice with it. I wish the instructions were simply 1 cup of this with 3/4 cup of that and not convoluted but if I was a bit more patient maybe it wouldn't matter
