Apple, pear, and walnut woods,
especially the fine-grained sorts, may be satisfactorily ebonized by
first boiling in a glazed vessel, with water, 4 ounces of gallnuts,
1 ounce of logwood chips, 0.5 ounce of green vitriol, and 0.5 ounce
of crystallized verdigris, these being filtered while warm and the
wood brushed a number of times with the hot solution.
Thus stained black, the wood is then
coated two or three times (being allowed to dry completely after
each coating) with a solution of one ounce of iron filings in a
quart of good wine vinegar. This to be prepared hot and allowed to
cool before it is used.
