Norway Maple Bowl
This Norway maple partially closed bowl is from the same tree as bowl #51 in this section. The chatoyance or cat's eye gem appearance is due to the grain which is curled rather than straight.
This tends to happen in crotch areas and stump areas of the tree where gravitational stresses deform the grain pattern. Wood from elsewhere in this tree was straight grained and showed none of this appearance.
The only reason I was able to get this piece of wood is because the owner could not split it. The straight-grained-easy-to-split logs ended up as firewood. So he got the wood he wanted and I wanted the wood that he had no use for. Each thought they had the better part of the arrangement.
