| From what it says, it is a coating that covers the stain on/within a nucleus and I guess essentially provides a blank canvas. Not sure why you'd want to do this process which would add cost to the nucleus. Black pearls grow happily on stained nuclei and no colouration shows through so why bother masking it? Unless it also provides some other benefits.
We have experimented (as have others) with growth hormones, etc but no definitive just yet. |
