I bought a bag of brick-red silicone washers. Since additive free silicone is clear, there must be something that's been added to their formulation. Does anyone know what might have been added, if anything will leach out, and if so, whether it's safe?
Thanks
Edit: This is a different company than the one that made my washers. According to this website, a tin additive imparts a red color. I wonder if I can assume that all red silicone washers have had tin added.
