Organ pipe

RoUed-zinc products in the form of strip, sheet, wire, and rod have many and varied commercial appUcations. Strip is formed into dry-ceU battery cans, mason jar covers, organ pipes, grommets, eyelets, and many other objects, some of which are subsequentiy brass or chromium plated (jewelry, medaUions, bathroom accessories, etc) (132). The zinc—carbon dry-ceU appUcation accounts for about one half the roUed-zinc consumption in the United States (see Batteries). Sheet zinc is used in photoengraving and also in the constmction of roofing and other architectural uses. Special high grade zinc with a...

In this mode, acoustic-pressure oscillations are similar to those established in a closed organ pipe. The resulting pressure oscillations then couple with the pressure-sensitive combustion processes to further excite the oscillating pressure and thus produce the high-pressure amplitudes.

Tin has many uses, including coating (tins/cans for food), alloys such as bronze, organ pipes, solder, and the float glass process. It is also important in laboratory syntheses, in spite of the well-known toxicity problems. 

Lead is also used in organ pipes, of course. Other uses include the lead-acid battery, radiation shielding, ceramic glazes, and in lead glass. It is a toxic element, and its organic derivatives are also toxic. Tetraethyllead was used for many years as an anti-knock agent in petrol.

Organ pipes today are made of a variety of woods (e.g., mahogany) and metal alloys, depending on the desired tonal quality, appearance, and cost. Most pipes are made of a varying mixture of tin and lead called spotted metal, but pipes with copper and zinc are also common.M It is widely believed that the higher the tin content, the brighter the tone and the shinier the appearance. Historically, tin was the preferred material for an organ pipe, yet the expense of the metal was always a consideration and a limitation. 

Pure tin exhibits two common forms in the solid state — a gray tin and a white tin. At temperatures above 13°C or 55°F, the more stable form of tin is the denser white tin. At lower temperatures, the white tin is slowly converted to the gray form, a more powdery substance. Prolonged exposure to the cold winter temperatures of northern Europe contributed to the loss of integrity and disintegration of many cathedral organ pipes. As a consequence of the progressive nature of the structural transformation, as the white tin metallic surface becomes covered with...

When I was at Organ Pipe Cactus N.M. I had been planning to smoke Salvinorin the following day while I was tripping on mescaline. However, the following day s journey entailed much extreme physical discomfort, as the temperature reached 120 and was over 100 throughout the day. 

It is also possible for a pure material to have several different solid phases. Hn, a material that was once used for organ pipes, can change from a uniformly solid white tin to a powdery gray tin at low temperatures. This phase transition has been termed tin disease, or tin pest Ice can solidify into several distinct forms, including ice IX. Reportedly, Kurt Vonnegut, a chemist by training, was unaware of the actual existence of ice IX when he used the name in the plot for his novel Cat s Cradle ...
