WebHi, So over the past 7 years I have been working extremely hard in researching and trying to synthesize opal. It’s been hard because there was relatively no sources on opal synthesis at all. But I was able to figure out a process. So I was able to make the opal. Only problem is, that it lacks hardness. And when dried is a chalk like consistency.
