## Description

Product description Safe to use Alja-Safe is the world’s first alginate molding powder that does not contain crystalline silica (a known carcinogen). Alja-Safe is perfect for making single-use molds of the face, hands and other body parts. It captures detail better than other alginates, giving you a more accurate reproduction of your original. Certified Skin Safe - Material is skin safe and certified by an independent laboratory. Alja-Safe is easy to use and cures quickly. It reproduces fine detail and makes an excellent temporary mold – good for one or two reproductions of any body part. You can then cast plaster, gypsum, platinum cure silicone rubber, or Smooth-Cast 300Q ultra-fast urethane resin into the mold to make a reproduction. For making reusable molds of any body part, use Body Double silicone rubber. Visit Smooth-on website for more information on lifecasting and what these materials can do for you. IMPORTANT: This product has not been tested for and should not be used for dental applications. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question. Refer to technical bulletin for more information available at Smooth-on website.

Review: Ignore the nay sayers. This product is easy and fun to use. - 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.
Review: Great product! I will buy again - Product was delivered on time and worked as promised. I used this along with plaster bandages (ACTIVA Rigid Wrap Plaster Cloth) to make a half cast of a models face. The half cast came out perfect. The detail it captures is amazing. As a professional special makeup effects artist, I am very pleased with this product. I've never been disappointed by any Smooth-on products. Note when using this product: -The warmer the water is the faster it will set up. I like to used cold water to give me more working time. -You need to work quickly, it goes from a creamy texture to a solid before you know it. -Cover the model's eyebrows (or any facial hair they want to keep) with vaseline. It will take your hair out. -If used on the head, cover the model's head with a bald cap (it will take your hair out) -After a few hours the alginate will start to shrink and dry out, so be ready to more whatever plaster or resin in the mold as soon as possible. -Shrinkage can be fun! I got the alginate off the plaster in one piece (yeah! that doesn't always happen) and saved it by placing some very wet paper towels in the alginate so it would shrink without cracking. I checked on it every day. After a few days the face impression was about the size of my hand and slightly warped. I poured plaster into the smaller head mold. The result is a plaster cast of a slightly "S" shaped, shrunken head. It's just a fun, weird conversation piece and it totally freaked my model out (so it was worth the time). If you have extra time and extra plaster.... and you like weird stuff. :)

## 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.

### ⭐⭐⭐⭐⭐ Great for beginners and intermediates...
*by T***R on August 15, 2017*

Update: I have now used this product for over a year and it still works great. I'm on to cold number 2 and I have made over a dozen casting from the one bag. Again it will depend on how buig your projects are as mine are infant's feet and hands. I love it as much as when I first bought it. I wanted to make body castings of our newborn baby son's feet as he grows the first year and this has worked well! The one bit of advice I would recommend is making sure to dip the body part and pull it out and then put it back in to get rid of air bubbles. Also when filling with plaster pour slowly and rotate it around to fill all the little nooks and crannies before completely filling. The instructions were very informative and helpful in guiding me in obtaining good results. There is enough material to do several pours. I have done 3 babies feel and 1 set of clasped hands and one small test mix to test at the beginning using my thumb and still have enough for several more baby feet! I keep it twisted tied closed and in the box in a dry cool place and haven't had any issues over the past 12 months.
