Tablespoon made of rowan, finished with flaxseed oil.
The spoon is decorated by means of kohlrosing. This is an old technique that was already known to the Vikings. A knife has been used to cut the desired pattern into the wood. A coloured powder has been rubbed into those cuts. Originally charcoal was used, which explains the name of the technique. Because of the toxicity of coal powder, extra finely ground coffee powder has been used here. The cuts are then closed and the spoon is oiled with flaxseed oil. This ensures that the powder remains well trapped in the cuts.
