I was given a silver birch log about a year ago it was about 3ft long and about 4" thick so today I cut a few bits off to discover it had spalted and the bugs had chomped away at it but not being one to give in I turned some of it into two vases 7" and 8" tall the first one the bugs had chewed away at the edge the second one has a few holes in the foot purely ornamental with a polish finish enjoy
