Review: Cool new hobby! - It's great stuff! If used wisely you can make quite a few molds for small items. One pound is plenty enough for jewelrymakers and most hobbyists. It's easy to mix, easy to shape, and easy to mash onto items to mold them. It's a very forgiving material that allows mold-making to be a casual hobby. It doesn't stick to skin very much, and it's easy to scrape and clean up even with bare hands. After mixing the putty, you get about 3 minutes of normal working time and then maybe 5-8 minutes to fix mistakes. You can also use a nonstick material like burnished wood to flatten areas and fix edges when necessary. Today is my first day using it and I've made 5 molds throughout the day. I found that an exacto or scalpel knife blade is outstanding for trimming the excess material from these molds. Use your thumb to push/roll the excess away from the mold cavity, then slice it off. This thin, folded rubber won't resist your blade at all so you can make amazingly precise cuts. In my photo I showed how many grams it took to make each mold. (I found that a good rule of thumb is to make the backing have 2-3x as much mass as the initial layer. Use pinches to blend the layers into one solid mass.) Since taking the photo, I've filled every mold with more of the silvery epoxy. Can't wait to see the results! The first two molds, I poured epoxy into them within 20 minutes of demolding the original items. Through time, I will research this material more and try to answer the following: 1. How much heat can it take? 2. How does it work with mold release spray? Overall, it's super fun and well worth trying! UPDATE: A few days later, I have an answer for the 2nd question. Mold release spray hardly seems to make any difference. But I also have some advice. You should wash and dry these molds before using them for the first time. If you don't, the oils from the silicone putty might get into your epoxy. This is especially noticeable for small or thin items. The epoxy items cast in these molds were flexible like a gummy. After a few days they did fully harden, but it was a bit nerve-wracking to wiggle them out of the mold without bending or breaking them. I imagine this leftover silicone oil is also why people have problems with UV Resin. So, wash the molds!
Review: Good product, mix bare handed, works as intended! - EDIT: !! I AM CHANGING MY ORIGINAL REVIEW!! After doing research on different types of silicone base and catalyst, I found a study of the effects of nitrile, vinyl, and latex gloves. To summarize, this putty does not interact well with nitrile gloves. I used it bare handed and found that it would set up as expected and is genuinely a good product especially for the cost. I apologize for my original review and I guarantee I will be using this product again in the future. I recommend just using your bare hands to mix this putty due to there also being no residue left on your hands after mixing. Again, I am sorry and I hope this is helpful! Packaging says that the working time is 3mins and the curing time is 15-20mins. However, this putty almost never sets up or cures, even with prolonged vigorous mixing. When it does finally harden in the slightest, the putty easily falls apart. Please stay away from this product and look elsewhere.

*by W***E on May 14, 2026*

I almost gave this a 1 star and a bad review, BUT turns out I was the PROBLEM!!!! The first time I mixed it, I mixed more than what was needed. This made it hard to get out what I was trying to copy. It also created some very unwanted air bubbles and not to mention WASTE!!!! I retried it and used a much thinner covering. This did away with the air bubbles and made removing the casting a lot easier!!! I say if you want to try it, maybe mix a small amount and see how it works!!!!
