Famous Welding Quotes

The Ancient Britons’ secret weapon? Woad could be mixed with yellow from the meadow plant weld, or from another native plant, dyer’s greenweed (genista tinctoria; despite its English name it dyed yellow), to give the green that Robin Hood and his merry men famously wore. Red, another favourite medieval colour, could be obtained from the roots of another native plant, madder. Mixed with woad it produced a soft purple. A deeper purple came from a lichen, orchil, imported from Norway, or ‘brasil’, a wood imported from the East Indies and correspondingly expensive. The deepest purple came from kermes, derived from insects from the Mediterranean basin called by the Italians ‘vermilium’ (‘little worms’, hence vermilion) and by the English ‘grains’. Its cost limited it to the most luxurious textiles. A good pink could be had from the resin of dragon’s blood trees, although some medieval authorities traced it to the product of a battle between elephants and dragons in which both protagonists died. Most of these dyestuffs needed a mordant to give some degree of light-fastness – usually alum, imported from Turkey and Greece.

Stainless steel might have seemed an extravagantly expensive material for architectural decoration at first glance, but it was touted as being durable and worth the expense, which it proved to be. It has a tensile quality, which was ideal for covering large expanses, and it could be easily worked at the factory and welded at the site. Since it is alloyed with chromium, it resists abrasion and corrosion, and, when combined with nickel, it achieves an even shinier finish. Its use in the Empire State Building for the mullions that race up the sides is one of the great secrets of the building’s subtlety and aesthetic satisfaction. Perhaps its most famous use in New York is the crown of the Chrysler Building.
