## Description

This product is Made with High quality of material, It is easy to use. Gives best result. Grab it as soon as possible.

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.

## 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

### ⭐⭐⭐⭐⭐ Easy to use, strong, excellent detail capture
*by M***L on 27 April 2021*

Easy to use, great working time and strong upon curing. It's also well worth mentioning that the level of detail you can capture with this product is mind blowing. Work as advertised, and intended which is ideally what you want for any product at the end of the day.
