    I have a redwood burl top that I'm filling in the voids in with CA glue. Not sure why, but I believe kryptonite is growing in the wood... Question is why?

    Did you use garnet sandpaper?

    That is really weird. Interested to see if you find out whats causing that. Almost looks like you did it intentionally.

    So, no garnet. The green appears to be a cupric green and my guess is that impurities reacted with the CA.

    Maybe the tree grew close to a toxic waste dump. Or a bigfoot used to crap on the sapling. Or it might be a new hybrid redwood.
     
  11. It could be that the sap in the wood has had some sort of chemical reation with the CA glue...

    I think your on to something here. At least it makes sense as to the cause.
    I was going to dremel and fill with black ca glue, but after seeing some of the positive reactions to this effect, I'll "go green" and keep it. Besides, it's kinda growing on me... :)

    cool, I like it!

    maybe the CA is what goes green at the end of my frets?
    I thought it was the fret itself.

    CA is clear. Always. Any color will come from impurities. The green of your frets will be from the oxidation of the metal that is coincidentally trapped by any CA. Without seeing the green my guess would be nickelous oxide.
