For example, the pottery industry might require a product whose size lies between 55 and 65 pm, and the pendulum mill is capable of achieving this. A comparison between the Lopulco and pendulum mills has shown that, whereas the Lopulco mill would give a product 98 per cent of which was below 50 ptm in size, the pendulum mill would give 100 per cent below this size in the latter case, however, the power consumption is considerably higher. 

This process offers a route for the manufacture of complex shapes and, in the traditional pottery industry, is the accepted method for the production of teapots, milk jugs, figurines and large articles such as wash-hand basins. It may be necessary for the mould to be made up of a number of pieces so that the cast article can be removed. 

One universal type of concentrate was manufactured in Pug Mills of the type typically used to mix clay in the pottery industry. No one manufacturing method works for all polymers and generally the more versatile the process the less optimized it is for any one product. 

In Capital /, p. 270, note 2, there is a reference lo a petition for legislative enactment by 26 firms in the pottery industry. This, however, occurred in 1863, and is irrelevant for the explanation of the Factory Acts. 

Kaolins.— The first class of materials, usually of geologically primary origin, consists, in the purified state, of white clayey matter, containing both the crystalline and amorphous varieties of clay base. In some of these clays the crystalline constituents predominate, as in the North Carolina kaolins. The plasticity of these clays is but feebly developed, though where the granular matter has been broken down by the action of water or other agencies to the amorphous condition, a fair working quality may result. These clays, on account of their whiteness, are used in the pottery industries. 

Fuel Oil 1. Fuel oil 1 is a petroleum distillate that is one of the most widely used of the fuel oil types. It is used in atomizing burners that spray fuel into a combustion chamber where the tiny droplets burn while in suspension. It is also used as a carrier for pesticides, as a weed killer, as a mold release agent in the ceramic and pottery industry, and in the cleaning industry. It is found in asphalt coatings, enamels, paints, thinners, and varnishes. 

The economic life of the county was transformed by the industrial revolution—in the south, by the emergence of a new, primary iron industry based on coal instead of charcoal, and in the north, by the rapid growth of the pottery industry. Essential to this change was the construction of the network of trunk and local canals. By 1777, the Staffordshire and Worcestershire Canal and the Grand Trunk Canal linked the three estuaries of Humber, Mersey, and Severn, and by the early nineteenth century, Staffordshire had become the pivot of England s waterway system. 

Although probably the earliest ceramic articles were made entirely from clay, from very early times additions to it of other materials are known to have been made. At the present time in the pottery industry the chief raw materials used in conjunction with clay are the various fluxes and silica. In the refractories industry, increasing demand for specialized refractories has resulted in products containing little or no clay, such as alumina, magnesite and chrome such products are also classed as ceramics because in general they are shaped whilst wet and then fired in order to be hardened. 

In general, slip consists of fine (<10 xm) ceramic-powder particles that are suspended in a fluid. In the pottery industry, the liquid is usually water. The suspension can have a solid content up to -60 vol%. Defloccu-lents are added to the slip to modify the electrical environment of each particle so that the particles repel each other. 

In the early days of the pottery industry in England, transport of raw materials in and product out was inefficient. The costs of transportation had to be included in the...

Contact allergy to cobalt is common and is often associated with concomitant allergy to nickel or chromate (Chaps. 66, 67). This is interpreted as simultaneous sensitization due to combined exposure, because nickel is often contaminated with cobalt, and cement contains chromium as well as cobalt. Solitary cobalt allergy is seen mainly among hard-metal workers (Chap. 68) and in the glass and pottery industries. 

Decorators do develop irritant contact dermatitis from turpentine, as it is still used widely in the pottery industry because it less inflammable than white spirit or turpentine substitutes. There was an epidemic reported in the Stoke-on-Trent pottery industry of allergic contact dermatitis from Indonesian turpentine (Lear et al. 1996).

Mercaptobenzothiazole is a rubber chemical, an accelerant of vulcanization. It is contained in the mercapto mix . The most frequent occupational categories are metal industry, homemakers, health services and laboratories, building industries, and shoemakers. It is also used as a corrosion inhibitor in cutting fluids or in releasing fluids used in the pottery industry. 

This rubber vulcanization accelerator is used as a chemical in the rubber industry, especially in the production of synthetic rubber articles. Is contained in the mercapto mix . As a corrosion inhibitor, it can be found in cutting fluids or in releasing fluids in the pottery industry. It induces mainly delayed-type hypersensitivity, but a case of immediate-type hypersensitivity was reported in a dental assistant. 

China clay (kaolin) A white powdery clay obtained from the natural decomposition of granites. It is used as a filler in paints and paper-making, in the pottery industries, and in pharmaceuticals. See kaoli-nite.
