Logwood


(Bois de Campeche, Campeachy Wood)



Logwood is a dye wood from Central America, used for producing blues

and purples on wool, black on cotton and wool, and black and violet on

silk. It is called by old dyers one of the Lesser Dyes, because the

colour was said to lose all its brightness when exposed to the air.

But with proper mordants and with careful dyeing this dye can produce

fast and good colours. Queen Elizabeth's government issued an

enactment entirely forbidding the use of logwood. The person so

offending was liable to imprisonment and the pillory. The principal

use for logwood is in making blacks. The logwood chips should be put

in a bag and boiled for 20 minutes to 1/2 an hour, just before using.
