Q: whats the difference between oomo 30 and moldstar ?

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

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..

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
