Review on 🔬 Advanced 1.5lb Mold Making Material for Precision Molds by Michelle Langley

First there are a lot of negative reviews complaining about the mold not holding up or leaking water, to which I have to say: it's alginate; what did you think you bought This product is water activated and intended for very short term use. Most forms of alginate in the medical field are designed for ten minutes, after which they are discarded. It is not an alternative to silicone or urethane and you cannot cast multiple positives from it. After curing, you have 20 to 30 minutes to pour in casting material before the mold starts to crack. In most cases you will have to break apart and remove the mold to take an impression. This is a disposable product. Nonetheless, If you're looking for something skin-safe that reproduces great detail and don't want to spend money on platinum-cured silicone, this is a good option. I found that I had to use a little more alginate in my mix than recommended to get the right consistency and it took a little longer than stated on the packet, but my casting results were satisfactory and showed very good results. Detail. I still prefer silicone for larger projects, but it's a lot cheaper for something smaller, like the custom glove molds I made. It can also be done by one person working alone, while applying the silicone paste and creating the mother molds with one hand can be difficult. Just mix well. If possible, remove clumps and watch out for bubbles clinging to your positive original (this can be reduced by dipping your hand or mold a few times in the alginate to coat it before letting it mold ). Although it is possible to cast plaster of paris in alginate form. (and this is actually what comes with most hand cast kits) I have found that if left in the mold for too long the plaster tends to absorb water from the alginate and can become wet and brittle , which can make it difficult to disassemble without damage. I ended up getting better results with a fast-curing resin like Smooth-On's Smooth Cast 300, which heats up quickly enough to compensate for the low temperature and short pot life of the alginate library. If you use resin, you must pour it as soon as possible after the alginate has hardened. You need to make sure the inside of your mold is *completely* dry (moisture will prevent the resin from setting); and I recommend heating the mold first with a heat gun or high temperature blow dryer so the cold alginate doesn't exhaust the heat of the resin which will slow or stop the curing process. The photos I've attached show a resin mold cast in a perfect alginate mold. Container Note: Like silicone, alginate is self-cleaning, meaning it will stick and peel to most smooth, non-porous surfaces. That is, instead of everything
