I made this clock out of quarter sawn white oak. My daughter and I took a day trip to Motawi Tile in Ann Arbor to buy the tile. We also got to take a tour of the factory. The finish was achieved by fumigating with household ammonia for 2 days followed with Danish Oil and then a couple of coats of wipe on polyurethane. I tried the danish oil without fumigating and just didn't like the result as much.
