Table 3 Protocol for preparing an iron acetate solution for ebonizing wood

From: Iron acetate solution prepared from steel wool and vinegar for ebonizing wood

Step #

Protocol

 

Collect steel wool (#0000, super/extra fine); no need for washing the wool

1

A) Rhodes steel wool pad (old/aged is better than newly purchased)

Unravel pad to reveal 6 segments

Collect 4.0 g or 2 segments

(B) BriWax steel wool roll (newly purchased is fine to use)

Unroll and cut

Collect 4.0 g or 3.8 cm (1.5 in)

2

Add steel wool to a 1-pint glass canning jar or similar non-metallic, wide-mouthed vessel

3

Add 340 mL or 1.5 cups of Distilled White vinegar to the same vessel

4

Stir the mixture with a glass or plastic rod (e.g., plastic knife) and repeat every 24 h. Leave the mixture uncovered

5

After 3 days filter the mixture (through a coffee filter or fine cloth) to remove any remaining steel wool and other solids

6

Collect the liquid and store it in a glass or plastic bottle with cap. The liquid is colorless to orange at first and then becomes red to red–brown with time
