Is this a "chrysal"?

(1/3) > >>

FlintWalker:
This is on the belly of a hickory bow i've been experimenting with lately.  I roasted the belly over the stove. It picked up quiet a bit of speed and it's not showing the string follow it was but now it has these tiny little diagonal cracks.
  It won't hurt my feelings if it breaks but i'm just curious as to what these are and what caused them.  The bow had been shot before I toasted it and was a total dud. After toasting it, it shoots better than the first two I made. Scary how much better it shoots. I know it's gonna go south, just wouldn't be mine if it didn't.  What are these and how bad for a bow are they?   Thanks, Saw Filer

Yes, those are chrysals, but they are not bad. The bow could last a long time. If you are worried, you could apply a path of rawhide on the belly side and wrap with serving or silk - that will prevent them from getting any worse.

Pat B:
Yes, that is a fret, chrysal or compression fracture. What ever you want to call it.   Never try to remove a chrysal by scraping it off. You will have to reduce wood from either side of the fret to reduce the chance of more.   Pat

yes those are chrysals. I assume that the developed, because there might be a weak spot on the limb there. I could tell this from the wood grain showing in the pic. Right after the cryshals the grain or growthring gets wider, which means that there is more wood there.

jkekoni:
Is that round belly? It looks like one.

Hickory it not a wood for round bellies. Most woods are not.
