## 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
