It provided a safe alternative to the hazardous use of mercury in gilding metals, which was banned c1799.
c1660 – calendar movements were introduced to English longcase clocks.
The first longcase clocks in England, where the form was born, were produced about 1660.
Spring-wound table clocks and weight-driven wall clocks had been made for a couple of centuries prior to this, but they were not particularly reliable timekeepers and it was the invention of the long pendulum in 1657 (requiring a long case) that created a breakthrough in accuracy, and coincidentally introduced a new and unique form of furniture.
The construction of various parts can and will help in dating your antique clock.
Specifically the style and type of clock hand and the dial, both of which have varied over time.

Laprade has started threads involving a look at cases and dial scripts. I'm certainly not qualified in any way at offering insights but I know many of you are.So I'll start by posting what I think are some very nice hands from a Scottish long-case with round dial dating to about 1810.the seconds hand and calender hand are an exact match. I know they are probably not but has it ever been known to use gold when crafting long-case hands?Painted longcase and grandfather clock dials are found in many different sizes and styles, English clock dials are generally square or arched top, usually makers did apply their name to the dials of clocks they made, however Painted dial do deteriorate over time with sunlight, fires, and smoking, detail fades and can be rubbed away with cleaning and making it difficult to identify a maker.With Help from improving forensic technology and careful restoration techniques it is usually possible to identify information missing from a painted dial so they can be restored to their original condition using originally used materials carried out by an experienced qualified restorer.
