Daniel Swarovski (October 24, 1862 – January 23, 1956), formerly Daniel Swartz, was born in northern Bohemia (now the Czech Republic). His father was a glass cutter who owned a small glass factory. It was there that a young Swarovski served an apprenticeship, becoming skilled in the art of glass-cutting. In 1892 he patented an electric cutting China machine that facilitated the production of crystal glass.
In 1895, Swarovski financier Armand Kosman and Franz Weis founded the Swarovski company, originally known as A. Kosmann, Daniel Swartz & Co., which was later shortened to K.S. & Co. The company established a crystal cutting China factory in Wattens, Tyrol (Austria), to take advantage of local hydroelectricity for the energy-intensive grinding processes Daniel Swarovski patented. The Swarovski Crystal range includes crystal glass sculptures and miniatures, jewelry and couture, home decor, and chandeliers.
All sculptures are marked with a logo. The original Swarovski logo was an edelweiss flower, which was replaced by an S.A.L. logo, which was finally replaced with the current swan logo in 1988. To create crystal glass that lets light refract in a rainbow spectrum, Swarovski coats some of its products with special metallic chemical coatings. For example, Aurora Borealis, or "AB", gives the surface a rainbow appearance.[8] Other coatings are named by the company, including Crystal Transmission, Volcano, Aurum, and Dorado. Coatings may be applied to only part of an object; others are coated twice, and thus are designated AB 2X, Dorado 2X etc.
In 2004 Swarovski released Xilion, a copyrighted cut designed to optimise the brilliance of Roses (components with flat backs) and Chatons (diamond cut). The Swarovski Group also includes Tyrolit (makers of abrasive and cutting China tools); Swareflex (reflective and luminous road markings); Signity (synthetic and natural gemstones); and Swarovski Optik (optical instruments such as binoculars and rifle scopes).
The company runs a crystal-themed museum, Swarovski Kristallwelten (Crystal Worlds) at its original Wattens site (near Innsbruck, Tyrol, Austria). The Crystal Worlds centre is fronted by a glass-covered head, the mouth of which is a fountain. The glass-covered Crystal Worlds houses exhibitions related to, or inspired by, the crystals – but do not include explanations of how the famous designs are made, produced or finished. Swarovski work was recently exhibited at Asia’s Fashion Jewellery & Accessories Fair based on the concept of a single continuous beam of fragmented light travelling through a crystal. (Wikipedia)

Relay Contact Cleaning

I find the best way to clean such contacts is to soak a strip of paper in propan-2-ol and run in between the contacts. It’s abrasive enough to shift dirt but not to damage the plating on the contacts.
