Abstract

A method of quality improvement of wooden articles, such as improved preservation of wood through impregnation thereof. The impregnation is carried out by immersing the wooden articles in a bath of hot linseed oil or similar vegetable oil heated to at least 110 DEG C, whereby the water present in the wood evaporates and diffuses through the wood and the oil while the hot oil simultaneously penetrates into the pores and cavities of the wood. The wooden articles are then taken out of the bath and the oil oozed in is made to cure and thereby to stiffen the wood. During the immersion of the wooden articles, the linseed oil bath has a temperature of up to 250 DEG C, preferably near 250 DEG C. An insecticide and/or fungicide has been added to the linseed oil. As a result, the finished wooden articles do not warp or display cracks or crevices and the wooden articles are resistant to insect or fungus attacks.
