ABSTRACT:
Freshly sawn green timber is branded with identification or grading symbols sing an aqueous acid solution of ferric ions to produce blue-black markings. A suspension of iron oxides in a solution of ferric chloride and ferric nitrate produced by dissolving iron in a mixture of hydrochloric and nitric acids gives particularly good results.
