Steuben Glass is an American art glass manufacturer, founded in the summer of 1903 by Frederick Carder and Thomas G. Hawkes in Corning, New York, which is in Steuben County, from which the company name was derived.
The glass floats on the tin, and levels out as it spreads along the bath, giving a smooth face to both sides. The glass cools and slowly solidifies as it travels over the molten tin and leaves the tin bath in a continuous ribbon. The glass is then annealed by cooling in an oven called a lehr. The finished product has near-perfect parallel surfaces.
These were used to stretch glass to make tubes for the six faceted cut and polished seed beads then in demand. On 6 March 1849, Josef Riedel bought a new glassworks, with his own money, from Ignaz Friedrich, a textile entrepreneur and glass trader. The new glassworks was based in Polaun near Klein Iser and had a wood-burning furnace.
[4] [5] Some gold and silver coins were reeded to discourage clipping, i.e. scraping off the precious metals from the edge of the coin, to maintain its stated value in precious metal. [4] This practice was made more difficult through the implementation of reeding by Isaac Newton in 1698, [ 6 ] during his time as warden of the Royal Mint .
Pressed glass (or pattern glass) [1] is a form of glass made by pressing molten glass into a mold using a plunger. [2] Although hand pressed glass has existed for over 1,000 years, the use of a machine for pressing was first patented by Pittsburgh glass man John P. Bakewell in 1825 to make knobs for furniture.
Glass can be "double rolled", which means it is passed through two cylinders at once (similar to the clothes wringers on older washing machines) to yield glass of a specified thickness (typically about 1/8" or 3mm). The glass is then annealed. Rolled glass was first commercially produced around the mid-1830s and is widely used today.
Alto and tenor saxophone reeds.. A reed (or lamella) is a thin strip of material that vibrates to produce a sound on a musical instrument.Most woodwind instrument reeds are made from Arundo donax ("Giant cane") or synthetic material.
A double reed [1] is a type of reed used to produce sound in various wind instruments.In contrast with a single reed instrument, where the instrument is played by channeling air against one piece of cane which vibrates against the mouthpiece and creates a sound, a double reed features two pieces of cane vibrating against each other.
