Expert carvers don’t need to sand. They are skilled enough to tool finish their work. I’m not that good and find I do need to sand most of the stuff I’ve carved to make it look decent.
Recently, I saw a photo on the spoon carving FB site where the carver used the Japanese technique of Shou-sugi-ban to finish his piece. I knew something about this method as our nephew charred the siding on the house he is currently building. The idea behind scorching the wood is to create a long lasting and low maintenance finish. It can also be quite beautiful.
This video demonstrates the technique used on siding.
I recently carved a bowl from birch. It had some hidden knots and imperfections that made finishing the concave part of bowl difficult. Then, I dried it too quickly and it developed a big check (split). I decided this was a candidate for Shou-sugi-ban. Subsequently, I carved a spoon out of a left over piece of cypress and wasn’t happy with some of the detail. The cypress spoon became a second candidate for “The Art of Charred Cedar”. A running mate, if you will.
I made an executive decision that it didn’t have to be cedar for me to put it to the torch. Holding a hissing propane burner to wood takes a bit of bravery when you don’t know what you are doing. It went pretty well, however. Only a few flames which I was able to stamp out with my foot without doing more damage to the piece. I didn’t char the inside of the bowl, just the outer edge and the bottom.
I am happy with the result. There is also linseed oil on the bowl and spoon but I would like to give both more of a glossy aspect so will keep working on finishes. The trick, I discovered, is keeping the torch moving so the piece doesn’t burst into flames. I got a bit carried away and did some serious charring of a couple of edges.
I expect I will experiment with this on other pieces. Here’s a business that specializes on shou-sugi-ban.
