Those of porcelain is the most common. It is a tea pot purple sand was a famous in China in particular has been made ​​in Jiangsu Yixing kilns (Murasakidoro).its because the clay to produce here turned out to contain a lot of iron, it exhibits a black or purple red brown, this was called Shudoro, and Murasakidoro after firing at bake pottery unglazed. The same is also made Wedgwood kiln of England Yorozu old grilled Japan, and Tokoname posterity, Shudoro of these products Murasakidoro is the mainstream of the teapot in Japan.

Porcelain Imari, Kutani, Setoyaki, such as Satsuma many in Japan. In addition, and bake pottery such as Tamba and Bizen ware, such as those made ​​of earthenware Mino, such as Hagi-sho, many types have been produced very. I also seen this other, such as those made ​​of iron, stainless steel, aluminum, glass, made ​​of stone.

Those made ​​of stoneware or porcelain, is overwhelming teapot of tea, silver also many, those of pottery made ​​relatively small. Including stoneware Jasper ware of Wedgwood, porcelain teapot is made in the name of many of the kiln Western Europe.

Plastic, helical, nylon, phenolic resin is used handle, knob. There are things of screwing and which are integrated.

Metric Display

It is a notation that can be seen widely in automobile tires today. it was with "205/55 R16 91W", R = tire structure 55 = aspect ratio width of 205 = tire (mm), (%), (radial), 16 = rim diameter (inches), 91 = is the tire it is indicated (270km / h) maximum speed index showing the load to be supported (load index), W = is guaranteed by the tire. Numerical units are in inches rim diameter, the width of the tire are displayed in millimeters. A flat rate, (written as flat rate for tire. It. Different meaning to be written as flat rate) are expressed in percentage of the tire width the width of the side wall portion.

In addition, grip performance steering stability, braking performance, at high speeds can be improved (the height is lower than the width) flat rate as low as things, limit speed, such as cornering ing time is improved, and safety even at high speeds traveling tend to be run to the. On the other hand, the ride comfort becomes hard, running sound becomes large to easily pick up the coarseness of the road surface, when the passenger car, and a high aspect ratio, if economy-oriented comfort and to select - (60% 30) having a low aspect ratio, if sports driving performance-oriented, - (82% 65) things. Because it is also apply mutatis mutandis to the bias tire, this metric standard notation is represented by the condition, such as "180 / 60-17" cases, such as motorcycles.

Inch display

The notation is often seen in the bias tire, but it may also be used for radial tires. If it was with "3.50 S 18 4PR", which represents the maximum speed at which the width of the tire = 3.50, S = is guaranteed in the tire, the inner diameter of 18 = tire, the tire 4PR = strength. Display here is an inch all. Flat rate, have become 80 in 5.10 and 100,3.60 usually.

It is expressed as and "5.00-10 8PR" In the case of automobile tires, and thus the representation between the inner diameter of the tire and the width of the tire represents a tire structure. In this case, - it shows the bias tire = (D or hyphen). Is represented R next to the "5.00R10 8PR" In the case of radial tire. B is appended in the case of a bias belted tire, represented as "5.00B10 8PR".

Letter Display

Notation that was seen in the tire to be used in American cars to medium-term the 1960s and 1970s, aspect ratio and the outer diameter of the tire, that describes the form in order rim diameter, but I sorted by alphabet outer diameter of the tire thing is a feature of the maximum. If it was with "A78-15", A = the outer diameter of the tire, 78 = aspect ratio (%), - = represents the (inch) tire construction (bias), 15 = rim diameter, the alphabet A to Z in principle The progresses, the outer diameter of the tire is going to increase.

Notation which is not used only one time very well in America, automotive rim diameter corresponding to only 15 inches and 14 inches. (Which is also a flat rate does not exist only in the letter display) 78 flat also flat rate, three 70 flat, 60 flat there are only. Most of which are also bias tire tire structure, Lazear Rutaiya letter display was also present in the medium around the 1970s.
