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!
Review: The Perfect Product for Artists and Engineers - 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 desertcart, 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.

## 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

### ⭐⭐⭐⭐⭐ Great for quality molds
*by J***R on September 29, 2025*

This has been a go to for me for quite a while. It's somewhat thicker, so helps with leaking through the smallest spaces. Very easy to use, and I've had great luck getting a high level of detail in my molds. I really haven't had much trouble regarding quality and durability of molds I've made. I can usually get a very reasonable amount of castings before the molds start to show wear. I'm sure there is better stuff out there, but I'm very satisfied with the quality I get out of mold star.
