Victorian Slate Mantel Clock

• Victorian Period - The Victorian period of furniture and decorative arts design covers the reign of Queen Victoria from 1837 to 1901. There was not one dominant style of furniture in the Victorian period. Designers used and modified many historical styles such as Gothic, Tudor, Elizabethan, English Rococo, Neoclassical and others, although use of some styles, such as English Rococo and Gothic tended to dominate the furniture manufacture of the period.
  
  The Victorian period was preceded by the Regency and William IV periods, and followed by the Edwardian period, named for Edward VII (1841 ? 1910) who was King of the United Kingdom and the British Dominions and Emperor of India for the brief period from 1901 until his death in 1910.
• Pendulum - The pendulum was discovered around 1602 by Galileo Galilei, and was adopted for time keeping by the Dutch mathematician and natural philosopher, Christiaan Huygens, who excelled in astronomy, physics, and horology.
  
  The pendulum comprises a metal rod usually of brass or steel with a metal disk, known as a bob, at the end. The movement of the pendulum is driven by weights or a spring, and as a pendulum swings in a regular arc, it was found accuracy could be controlled to within a few seconds a week.
  
  Timekeeping can be adjusted by changing the height of the bob on the rod, making the pendulum either swing slower or faster.
  
  The disadvantage of the pendulum was that changes in temperature also changed the length of the pendulum, interfering with the accuracy of the clock, and so in the 18th century two types of mercurial pendulums were invented which countered the movement in the steel rod.
  
  The pendulum was the world's most accurate timekeeping technology until the invention of the quartz clock, regulated by a quartz crystal, in 1927.
• Brocot Escapement - The Brocot escapement was invented by the French clockmaker Achille Brocot in 1828. It is a type of escapement, which is a mechanism in a timepiece that controls the movement of the gears and regulates the timekeeping accuracy.
  
  The Brocot escapement is a variation of the detent escapement and it is used in pendulum and spring-driven clocks. It uses a pair of pallets that engage and lock the escape wheel, allowing the clock's power to be transferred to the balance wheel. The escapement also allows the clock's gears to advance in small, precise increments, which helps to improve the clock's timekeeping accuracy. The Brocot escapement was widely used in 19th century for both domestic and public clocks, also it was widely used in marine chronometers.
  
  The Brocot escapement is known for its high accuracy and stability
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Bevel / Chamfer - In furniture making, a chamfered corner refers to a technique used to create a smooth, angled edge on the corner of a piece of furniture. This is typically done by cutting away a small portion of the corner at an angle, typically 45 degrees, creating a diagonal edge, rather than a sharp 90-degree angle. This technique can be used on various parts of a piece of furniture such as table legs, drawer fronts, or door frames. Chamfering can add visual interest to a piece and can help to soften the overall look of a piece of furniture. It is often used in conjunction with other techniques, such as rounding edges or using contrasting wood species to create a more elegant, sophisticated look. Chamfering is a simple way to add a touch of elegance to a piece of furniture and it is a common technique used by furniture makers.
