I love these clear polymer stamps, but it seems like the lye "eaten" the stamp, making the stamp opaque when the soap gel is hot. I don't care if the stamp is transparent or not, I just worry about anything toxin there. I know the stamp is safe itself, but I don't know if it is still safe with the hot lye and oil. Does lye(NaOH) or oil have chemical reaction with the stamp? when the soap gel is not hot, the stamp looks OK.
I really like these stamps, they are much less expensive than those soap stamps. If it is safe, I'm going to keep using it. But if it is not safe...
