In this subclass, the following terms or expressions are used with the meaning indicated:
Drying-oil | Unsaturated fatty oil, such as linseed oil, tung oil, poppy seed oil, perilla oil and walnut oil, that becomes hard, tough and elastic upon exposure to the air when spread into a thin film. |
French polishing | Wood finishing technique for wooden furniture that results in a very high gloss, deep colour and tough surface; it consists of applying many thin coats of shellac using a rubbing pad. |
Natural resin | Water-insoluble mixtures of compounds derived from trees, especially conifers, e.g. gum, tall oil rosin, pine tar, pitch, shellac. |
Siccative | Drying agent; a substance that promotes drying, e.g. linseed or flax seed oil. |
Turpentine | Resinous exudate or extract obtained from coniferous trees, particularly those of the genus Pinus. |
Voltolising | Subjecting oils to treatment with an electric discharge. |
