I have quite a few old bottles that have "opal coloring" on the outside. I'm not sure if that is the correct term. It looks sort of like a rainbow effect on the bottle. Are there any ways to remove this?

The iridescence and scaling of the glass is actually the product of the decomposition of the glass. It is typically the result of submersion in acidic ground-water for a long period.Adena_man said:I have quite a few old bottles that have "opal coloring" on the outside.
