Where does your opal come from. There should be no need to add anything to your opal to prevent it cracking. (crazing) I have been working opals for many years. Some opal will craze when it dries out. However our opal comes from places with extremes of temperature and they never loose their moisture. Usually once polished the opal needs no other treatment. If yo9u just want to look at it. Place it in a jar of water and change it every once in a while. The water fills the pores or scratch marks and makes the opal shine as though polished.
