Can someone tell me what the number dictates in the product name OOMOO 30? I've recently used OOMOO 25 to make a texture stamp. But I'm not sure what the difference is between the numbers since I'm still new at this. Does the number tell you the level of harness or cure time?

[SmoothOnInc]

@Narcomics In the case of OOMOO, the '25' or '30' is the hardness. The OOMOO 25 also cures faster (75 minutes vs. 4 hours)

is it safe for kitchen wares?

[SmoothOnInc]

@MrMt1600 It does not have a food safety rating.

HAVE YOU EVER MADE THEM IN CLEAR RESIN

[SmoothOnInc]

@niquil454 You can use clear resin in a silicone mold, our Crystal Clear resin is a UV resistant material.

he i was wanting to get one of these kits and was wondering does it tell you the how much of each i need to use make the rubber and is there something bad that happens if it sits for more than 6 hours also can you measure by cups and ounces or do you have to use a scale?

[Narcomics]

@SmoothOnInc Ahhh ok, I see I see. Thank you so much for clearing that up. I'm assuming the higher the number, the harder the rubber? Or is that the other way around? Thank you for helping me out here.

@Narcomics harness = hardness* sorry typo.
