Workability

Generally easy to work with both hand and machine tools, though it has a moderate blunting effect on cutters; glues, stains, and finishes well

Finish Recommendations

Takes stains, oils, polyurethane, and lacquer exceptionally well; shellac is also effective, but care should be taken with iron fasteners due to tannin reactivity

Notable Features

Contains tyloses which plug the pores making it water-resistant; high tannin content which can react with iron to cause black/blue discoloration
