  • Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
  • Polychrome - Made or finished in many colours. For furniture, it is used to indicated a painted finish.
  • Duplex Escapement - A duplex escapement is used in clocks and watches to control the release of energy from the mainspring to the timekeeping mechanism. The duplex escapement is a variation of the lever escapement and is characterized by the use of two pallets, or escape wheels, to control the release of energy.

    In a duplex escapement, the balance wheel, which oscillates back and forth, alternately pushes against the two pallets. This allows the energy stored in the mainspring to be transferred to the balance wheel in a controlled manner, keeping the timekeeping mechanism accurate.

    One of the advantages of the duplex escapement is its relatively low friction, which helps to maintain accurate timekeeping and prolong the life of the clock or watch. Additionally, the duplex escapement is relatively easy to maintain and repair, making it a popular choice for clockmakers.
