So I just read a review of a product made of TPR Silicone. The reviewer said that TPR has a safety rating of 7 and is slightly porous (which is correct). Then they said that Silicone has a safety rating of 6 and is more porous than TPR. In truth, TPR Silicone does have a rating of 6, I think she just got mixed up. I left a comment politely correcting the reviewer, letting her know that Silicone by itself is rated 10 and non-porous, and I hope she does not take it the wrong way. I also linked her to the materials page. So I wanted to take this opportunity to point out that maybe we aren't being as aware of our materials as we should. Just in case anyone has trouble finding the materials safety page, it is here link. Also, when looking at an item's main page, you can click on the name of the material and it will take you straight to that material's info page. Does anyone else have any information resources, or at least some suggestions on staying up to date on safety info and utilizing it correctly?
