A furo is a “drying cabinet”. It’s where you put urushi lacquered objects to keep them warm and humidified until the lacquer has fully cured. Depending on the type of lacquer, this could take a number of weeks. In my case “furo” is actually short for “furnace room”, which is a nice warm room in the house that also contains the hot water heater.
I’ve been working on a couple of wooden box projects, and I decided to finish them with walnut oil. Walnut oil is a drying oil (like boiled linseed oil), but it contains no chemical drying agents like BLO does and is food safe. The down side is that it takes about a month to cure, so I can’t show these boxes as finished projects for some time.
Both boxes are constructed primarily of 1/4″ cherry scants. These are off-cuts from trimming down the legs of the two cherry marudai I made. The floors of both boxes are bookmatched resawn maple. The floor of the smaller box is the result of trying to make the larger box and having it come out a little small due to lack of planning. The lid of the smaller box is more 1/4″ cherry that has been edge-glued into a single panel. The lid of the larger box is 3/4″ rough-sawn cherry salvaged from the scrap pile at Mr. Arimoto’s shop. Once the oil went on the raw surface of the cherry, the whole thing went deep and beautiful.
I’m going to try to resist the urge to peek in on them constantly. We’ll see how they look in a month.
