Manufacturer and builder 8 tai 9, 1869

Dr. Stoltzel adds another to the many recipes already given for staining wood of a brown color. He first of all paints over the wood with a solution made by boiling one part of catechu (cutch or gambier) with thirty parts of water and a litt le soda. This is allowed to dry in the air, and then the wood is painted over with another solution made of one part of bichromate of potash and thirty parts of water. By a little difference in the mode of treatment and by varying the strength of the solutions; various shades of color may be given with these materials, which will be permanent and tend to preserve the wood.
