I'm not sure I follow ... Hardened as in become brittle? Or as in "not gooey anymore" ?
It has the usual consistency of cured silicone ... soft but not gooey. Hmmm, don't know how to really describe that texture.
I had a batch of silicone that was either old or maybe got too cold in storage, and it never really fully cured. After a couple of days of sitting you could still smoosh your finger through it.. Is that what you mean? Anyhow it's not like that, it did fully cure.
