A seventeenth century wheelock

Hullo Fernando
For the most part the gilding is contained roughly within engraved lines but in some areas , such as the top of the flashpan cover it isn't. It appears the amalgam was simply painted onto the steel with a brush to enhance , rather than simply to fill in the engraved design. Where engraving is present within a gilded area the gilding is only on the flat surface , and does not fill the engraved lines.

The Royal Armouries research department claims to have found traces of copper as well as mercury in fire gilding as applied to blued armour and suggests that a wash of copper ( malachite ? ) may have been applied to help the mercury gold amalgam to adhere. Because the mercury volatises at a relatively low temperature the precipitation of the gold and the colour treatment of the steel can occur at a similar temperature. Obviously , as you know the quality of the blue depends on the carbon content of the steel so we can assume the lockplate has previously been case hardened.

Best wishes

The first most probably Munich, Bavaria, ca. 1550-55, belonging to a small saddle arquebus (76 cm overall), and preserved in near-mint, pristine and unbelievably crisp condition.
I will soon post the arquebus comprehensively in a thread of its own; I refrain from labeling it as a long pistol as the square tubular backsight, as well as the gun's length and weight, clearly denote that it was aimed with both hands, the butt rested on the cheek.

The second sample in the Augsburg/Bavaria style, ca. 1565-1570, now detached but originally made for the same type of small arquebus as before. Though in fine condition as well, the state of perfect conservation does not quite match that of the foregoing mechanism.


Both samples formerly in the author's collection. Author's photographs.



Best,
Michael
