Molds made with Mold Star will last a long time in your mold library and are good for casting wax, gypsum, resins, and other materials. Cured Mold Star rubber is heat resistant up to 450°F (232°C) and is suitable for casting low-temperature melt metal alloys. One to One Mix Ratio Mold Star rubbers are mixed 1A:1B by volume (no weighing scale necessary) for precise measurements even at a very low mass and cure at room temperature with negligible shrinkage. No Vacuum Degassing Mold Star silicones feature relatively low viscosities making vacuum degassing optional and is not required for most applications. A uniform flow will help minimize entrapped air. Mold Star Translucent Series 14T, 19T, 20T, and 31T fast curing silicones for making molds or casting into alginate molds. They offer an infinite number of color effects achieved by adding Silc Pig silicone pigments or Cast Magic effects powders.

With a 6 minute pot life and 30 minute cure time It can even be used in forensics to capture evidence impressions in the field. Review: Survived my chaos and still made a perfect mold - I bought this for a “quick little project” which somehow turned into me panicking, spilling silicone everywhere, trapping objects in glass containers, and questioning my life choices at 2 AM. And honestly? This silicone still performed beautifully. The mix ratio was easy enough that even a sleep-deprived beginner could handle it, the bubbles were minimal, and the cured mold came out flexible, strong, and super detailed. I used it for casting decorative pieces and it picked up every tiny texture perfectly. Biggest surprise: it actually gives you enough working time before curing, so you’re not fighting the clock like in some other products. Demolding was also way easier than expected. A few helpful notes for beginners: * Mix slowly if you want fewer bubbles * Don’t underestimate how well this stuff sticks around once spilled * Use gloves unless you want “mysterious silicone fingerprints” on everything you own for 3 days Overall, excellent product. My project survived, my sanity mostly survived, and now I want to mold everything in my apartment. Review: Amazing - ⭐️⭐️⭐️⭐️⭐️ Excellent Quality Silicone for Molds!. Silicone is fantastic! It’s easy to mix and pour, and it captures every fine detail perfectly. The curing time is very reasonable, and once set, the mold is strong, flexible, and durable — perfect for resin, clay work. releases cleanly, making the whole process so much easier. This silicone gives professional-quality results every time. I’ll definitely keep using it for all my future projects! ## Features - Mold Star silicones cure to soft, strong rubbers which are tear resistant and exhibit very low long term shrinkage - Molds made with Mold Star will last a long time in your mold library and are good for casting wax, gypsum, resins, and other materials - Easy to use platinum silicone mold mix - Cures to a soft, stong, tear resistant rubber ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ETAY8RI | | Best Sellers Rank | #15,377 in Arts, Crafts & Sewing ( See Top 100 in Arts, Crafts & Sewing ) #147 in Sculpture Molding & Casting Products | | Brand | Smooth-On | | Brand Name | Smooth-On | | Color | Blue | | Customer Reviews | 4.6 out of 5 stars 740 Reviews | | Item Dimensions | 7.52 x 5.98 x 2.99 inches | | Item Weight | 0.59 Kilograms | | Item dimensions L x W x H | 7.52 x 5.98 x 2.99 inches | | Manufacturer | Smooth-On, Inc. | | Manufacturer Part Number | moldstar30 | | Material | Silicone | | Material Type | Silicone | | Model Number | COMINHKR067156 | | Number of Pieces | 1 | | Shape | Star | | UPC | 751635227415 | | Unit Count | 1.0 Count | | Warranty Description | No Warranty | ## Product Details - **Brand:** Smooth-On - **Color:** Blue - **Item dimensions L x W x H:** 7.52 x 5.98 x 2.99 inches - **Material:** Silicone - **Shape:** Star ## Images ![Smooth-On Mold Star 30 Silicone Mold Making Kit - Easy to Use & Long-Lasting Silicone Mold (2-Pound) - Image 1](https://m.media-amazon.com/images/I/81MxIlm4+KL.jpg) ![Smooth-On Mold Star 30 Silicone Mold Making Kit - Easy to Use & Long-Lasting Silicone Mold (2-Pound) - Image 2](https://m.media-amazon.com/images/I/71MKTOvqFRL.jpg) ![Smooth-On Mold Star 30 Silicone Mold Making Kit - Easy to Use & Long-Lasting Silicone Mold (2-Pound) - Image 3](https://m.media-amazon.com/images/I/719AiOp-2JL.jpg) ![Smooth-On Mold Star 30 Silicone Mold Making Kit - Easy to Use & Long-Lasting Silicone Mold (2-Pound) - Image 4](https://m.media-amazon.com/images/I/810O9OZWSoL.jpg) ![Smooth-On Mold Star 30 Silicone Mold Making Kit - Easy to Use & Long-Lasting Silicone Mold (2-Pound) - Image 5](https://m.media-amazon.com/images/I/71wzkM3noYL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: whats the difference between oomo 30 and moldstar ?** A: OOMOO 30 has a Shore hardness rating of 00-30, which is about as squishy as a gel shoe insert. Moldstar 30 is a hardness of Shore A-30, which is closer to pencil eraser hardness. It’s confusing, but there are 2 Shore hardness scales and a 30 on one is very different from a 30 on the other. In the description when it talks about hardness, pay attention to whether it says Shore A or Shore 00. **Q: What color is this silicone? Can I use mica powders to color it** A: It is blue when mixed, and very opaque, so I doubt powders will be able to color it much if at all. If you're looking to label your molds, I've 3D printed mirrored text using a raft, and set it into the mixed material. It floats, and pulls away cleanly once the material is cured. If you want a platinum cure 2 part silicone around shore-A 30 you can color, I might suggest DragonSkin 30 or Platsil Gel-25. **Q: Hi. i've made a wax mold of a small animal bone using this silicone method. i'm curious if i can use clay as well. i'm looking to make jewelry..** A: On Smooth On's website it states that this line of mold will not work with modeling clays that contain sulfur. Their website was very helpful and has lots of information: http://www.smooth-on.com/Silicone-Rubber-an/c2_1115_1341/index.html **Q: Is this food safe?** A: No. Smooth On does however make a food safe silicone called Smooth -Sil 940 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Survived my chaos and still made a perfect mold *by İ***A on May 18, 2026* I bought this for a “quick little project” which somehow turned into me panicking, spilling silicone everywhere, trapping objects in glass containers, and questioning my life choices at 2 AM.

The curing time is very reasonable, and once set, the mold is strong, flexible, and durable — perfect for resin, clay work. releases cleanly, making the whole process so much easier.

I’ll definitely keep using it for all my future projects! ### ⭐⭐⭐⭐⭐ The Perfect Product for Artists and Engineers *by K***S on June 26, 2022* I've been following this company for quite a while and I've used some of their other products such as Body Double and the level of quality in the final molds are breathtaking. What drew me to using Mold Star 30 is not only it's easy mix ratio of 1:1 by volume (you can also mix by weight, which I did for my current project in the pictures), its low viscosity makes cast complex parts and 3d prints easy. When you get these, stir each jar VIGOROUSLY with SEPARATE mixing sticks (I used a silicone stir stick or a drill with a mixing paddle, just drill slowly)! Not using separate sticks will cause cross contamination and you'll ruin the material. I also love the colours which helps with knowing when it's mixed, you don't want streaks in it. Now, prepping your part for molding takes some planning on your part and having sulfur free plastilina clay is HIGHLY RECOMMENDED and IMPORTANT, especially on wood mold boxes. Once the two parts are mixed in a cup you have 45 minutes to pour it into the mold. And I like that because I'm not rushing to pour and 45 minutes is PLENTY of time to stir the material and ensure a proper mix. In that time, you check your dry mold, fix a few things, and even take time degassing the silicone (the vacuum pot is optional). After pouring, you'll have to wait 6 hours until it cures. I ended up sitting the mold outside overnight to cure and doing this on a hot summer night helps immensely, especially when using the cups to check on curing. It was 97°F when I poured the silicone and the leftover material was already fully cured 3 hours later! Wow. The only knock I have on this product is the pricing for a pint and the price kept fluctuating here on Amazon, but you get what you pay for. This stuff is high quality and having a few pints actually is a good thing too, so you'll actually use it. Overall, this is easy to use but the learning curve mainly hinges on how well you plan your design and your mold boxes. Also, doing this outdoors helps with odors depending on what region you're in, especially where the air is drier. Once the price falls back to normal, I'll be getting more of these. ADDENDUM: My masters are done in PLA. For those of you who are using resin printed models, make sure the resin is COMPLETELY UV CURED before using this. ## Frequently Bought Together - Smooth-On Mold Star 30-1A:1B Mix by Volume Platinum Silicone Rubber - Pint Unit - Smooth-On Universal Mold Release - 14 Fluid Ounce Aerosol Can - Smooth-Cast™ 300: Bright White, Low Viscosity, Liquid Plastic Casting Resin - Pint Unit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/5665350-smooth-on-mold-star-30-silicone-mold-making-kit-easy](https://www.desertcart.ph/products/5665350-smooth-on-mold-star-30-silicone-mold-making-kit-easy) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-29*
