Review: Amazing for beginner mold makers- and some tips! - I am a doll sculptor teaching myself how to make replica parts of my pieces to expedite production, and I've experimented with a few different products for casting parts and replicating them: none of them beat out the results I got with Smooth-On! The 1:1 ratio is very simple and while you will waste some product in your first couple of rounds, you very quickly begin to be able to eyeball the measurements per mold; I've made 5 now and I can pour without weighing the pieces, without wasting product. I began with using foam core and hot glue to create the vessels in which to pour the silicone onto the pieces, but it was very messy and time consuming; I now swear by using Lego bricks instead and wrapping the edges of them with Frog Tape to avoid leakage. I haven't had any issues with curing, perhaps because every time I pour I mix each part in their respective pots for about 30 seconds before I pour to mix them. I'll then use wooden skewers to mix them together for about a minute before preparing to pour. I use a small spatula to help get the silicone off the sides of the mixing cup as I pour, ensuring I use as much product as possible per batch. Two-part molds have been easy and amazing with this. Just be sure to use sulphur-free clay and make keys in the clay before making your first mold part. As for the second part, I have the best results with simple Vaseline; I use a cheap paintbrush to apply the Vaseline to the mold and get into every crevice. I've had molds ruined with mold release spray not working well enough, but never had a single issue separating my mold parts with Vaseline. Smooth-On also makes my favorite material to cast my molds: their Liquid Plastic! The drying time is very fast and I can easily sand off the seams with fine grit sandpaper and buff it with a polisher. If I need to patch anything up, I can use air dry epoxy clay. Overall, Smooth-On is by far the brand I trust and have had the best results with as a self-taught mold maker and sculptor!
Review: Quality product but read this before buying. - I buy these pretty frequently for work and it's currently my favorite silicone for making molds. I've bought about 40 so far and would say about 15% arrive unusable, either from leaking or one of the components being completely coagulated (not the fault of the shipper by any means), but it's desertcart so getting replacements isn't difficult, especially since here in the US they typically arrive within a few days of ordering. If you are going to do a large pour with multiple sets, make sure to give each container a shake to make sure they're all ready to use. I've had no issues with thick pours (3-4 inches thick), just make sure you shake both containers REALLY well before use and make sure it's very well mixed and it is on solid colour without streaks or spots before pouring. It cleans up very easy, if it is mixed and spills, it peals off so satisfyingly after curing. After opening, I would recommend using it all within a week. It will cure while in contact with many things other silicones won't, like wood, polymer clay, and cured silicon of the same type(I like to use previously made molds as filler to save on material, just make sure it's cleaned very well with soapy water then let dry). I mix by weight, not by volume and typically end up with extra part B After having use all that I need from a set, I like to let the remanence of part A drip into a cup until there are no drips left, then mix with the proportionate part B and let set, then that can later be used as filler material on a later mold. I RECOMEND USING A SILICON TO RESIN RELESE SPRAY IF CASTING RESIN INTO YOUR MOLD. Definitely a fan of the quality and it's pretty easy to use. Definitely recommend vacuuming after pouring to get rid of air bubbles, not always 100% necessary but it helps. I've never had a batch not turn out so if it's sticky or doesn't set, it's most likely user error. I always let it set for 24 hours, longer shouldn't be necessary. The company doesn't like giving refunds in the event of the product arriving unusable so if a return must be made, do it 100% through desertcart and not the seller. That's about all I can think of to say about it.

## Questions & Answers

**Q: How large of a mold will this usually make? One large one? a few small ones? or is there a specified size reccommended?**
A: I molded an object with a volume of 37 ounces but it took a set and 1/4 of another set of these bottles. Safe bet that if you have a model with a displacement greater than the one I did, you need two sets. Some find the simplest way is to pour rice around your model then pour the rice into measuring cups to get a better idea of how much. The hollow mold that I made was about 11.5 inches high and 4 inches in diameter with a width of 1 inch on the sides and bottom of the mold. So.. to encapsulate a volume of 37 ounces with enough material so that the mold was free standing it was a set and 1/4 of silicone at the least. My mold did not have a top though, with a top, it would have been a set and a half, no question about it.

**Q: is this heat resistant?**
A: Not positive but aren't all silicones heat resistant. Great product.

**Q: How many ounces is each bottle?**
A: It is sold and labeled in Lbs.Part A is 1.2lbs and Part B is 1.6lbs and I can't find any label that provides info regarding ounces.  The dimensions are almost the same size as a 16 oz bottle so it's close to 16oz per bottle but that it an estimate.  Sorry I can't provide more info.

**Q: Is it enough liquid to make a 12" vinyl record mold?**
A: One would probably be enough, but it would be a thin coat. If you want the mold to be more durable, might go for a second just to hold the shape better.

### ⭐⭐⭐⭐⭐ Worth every cent
*by L***Z on March 23, 2016*

I tried a variety of mold making putties and rubbers available through big box craft stores, facing disappointment every time. I was hesitant to try something like this, since I had no experience working with silicone, but it's been a fantastic experience, and the only issues I've encountered were due to my negligence. While the silicone was much thicker than I expected, it takes to details beautifully, letting me replicate the tiny features of dollhouse miniatures perfectly. I haven't had issues with bubbles forming, save for my own mistake of creating a mold of a resin piece too freshly cast. The resin continued to outgas after it was covered in silicone, resulting in tiny bubbles that made that particular pour of silicone useless. It goes farther than I expected as well, and after creating 4 or 5 molds in the bottom of a cracker box, I still have 3/4ths of the containers remaining. I was concerned about one mold curing correctly because I failed to mix the bottom of the cup as thoroughly as I thought, resulting in a streaky mix of marbled blue and pink. Though it took longer for that mold to cure, it did cure properly, and I've not had any issues in the dozens of castings I've already made with it. Though the silicone mix is low-odor, I have chemical sensitivities and use an OV/P95-rated respirator when mixing and pouring, as the smell of a curing mold in my workshop did give me a headache after only a few minutes of exposure. Always make sure your work space is properly vented. Use of a respirator is encouraged in the instructions, but as many crafters overlook respiratory protection in their projects, I feel it's important to mention that it can make you sick if proper precautions are not taken! In all, I'm completely satisfied with this purchase and look forward to using it a great deal more in the future. I could have saved a great deal of time money by investing in this first, instead of being put off by a product I'd never used and considered too advanced for my uses!
