Re: Opal treatment?

Some opal, as it dries will loose color and many times turn white. Any liquid will revive it for a while but nothing found to be permanent. Some have used water, glycol, oil and other stuff. Some opal will gain fire as it dries also. Ther were some guys expermenting with a type of glycol that is used in oilfields with good results but eventualy found that it also is a temporary thing.
