Whilst perusing this page, I learned something new. I quoteth -
"After pulling about twenty or thirty castings, you will want to recondition your molds. You do this by baking them at a low temperature. Place some foil on a cookie sheet and then place your molds on the foil. Bake them for about four hours at 250 degrees. This will help redistribute the lubricants in the rubber to help retain its flexibility. "
It's interesting to me that this guy also uses a two-pour technique to preserve detail.

Well, 2 hours at 225 Farenheit didn't seem to help much. Didn't hurt, either, except for the waste heat from the oven.
