I'm turning a slightly spalted birch bowl, and found about a 1" crack about midway down the outside of the bowl. It isn't visible from the inside. I dribbled some thin and then medium CA to fill it, noticed that it sucked it up pretty fast. When I looked inside, the glue had penetrated all the way through and showed as darker than the surrounding wood (it was in the end grain).
My question is, once the bowl is given a final turn and a finish is applied, will the area treated with CA still be darker than the surrounding wood?
Thanks,
Dan
