About this motif
Before explosives were used, miners loosened hard rock with fire: they heated the rock until it cracked. This method was called fire-setting.
Peters' etching "Fire-setting at the coal face around 1700" shows a cross-section of a gallery with fires and miners underground, with trees and a meadow above. Image about 9 x 9 cm on an 18 x 24 cm sheet, black and white or hand-coloured, framed on request.
