Σελίδα 8 - TAKE a gallon of crude stinking oil, and mix with it a quarter of an ounce of powdered chalk, a quarter of an ounce of lime slaked in the air, and half a pint of water; stir them together, and, when they have stood some hours, add a pint of water and two ounces of...
Σελίδα 24 - A good Indian ink may be made from the fine soot from the flame of a lamp or candle received and collected by holding a plate over it. Mix this with the size of parchment, and it will be found to give a good deep color.
Σελίδα 83 - The universal architectural scale is, and is called, a diameter, being the diameter of the lowest or largest part of the column ; and, unlike the foot, inch or yard, is as various as the size of columns. By the diameter, of course, is meant that of the circle which forms the bottom of the column. Half of this diameter, or the length of the radius which forms the circle, is called a module, and is used, as well as the diameter, as a primary standard of mensuration, by some writers upon architecture....
Σελίδα 39 - The addition of the oxide of lead, or antimony, produces a yellow enamel ; but a more beautiful yellow may be obtained from the oxide of silver. Reds are formed by an intermixture of the oxides of gold and iron, that composed of the former being the most beautiful and permanent. Greens, violets and blues are formed from the oxides of copper, cobalt and iron ; and these, when intermixed in different proportions, afford a great variety of intermediate colors.
Σελίδα 7 - The distinctive characters of oil are inflammability, insolubility in water, and fluidity, at least in a moderate temperature. Oils are distinguished into fixed or fat oils, which do not rise in distillation at the temperature of boiling water ; and volatile or essential oils, which do rise at that temperature.
Σελίδα 3 - Tobacco-pipe clay from Dorsetshire is beaten much in water : by this process, the finer parts of the clay remain suspended in the water, while the coarser sand and other impurities fall to the bottom. The thick liquid, consisting of water and the finer parts of the clay, is further purified by passing it through hair and lawn sieves of different degrees of fineness. After this, the...
Σελίδα 8 - J of the whole, is poured off. Twelve gallons of linseed oil, and two of oil of turpentine, are then added to the clear part; and this, being well shaken together, is left to settle for two or three days, when it will be fit to grind white lead and all fine colours in. These, however, are to be thinned for use with linseed oil and oil of turpentine.
Σελίδα 3 - The yellow or queen's-ware is made' of the same materials as the flint-ware ; but the proportion in which the materials are mixed is not the same, nor is the ware glazed in the same way. The flint-ware is generally made of four measures of liquid flint, and of eighteen of liquid clay. The yellow ware has a greater proportion of clay in it. In some manufactories they mix twenty, and in others twenty-four, measures of clay, with four of flint. These proportions, if estimated by the weight of the materials,...
Σελίδα 3 - The salt is thrown into the furnace, through holes in the upper part of it, by the heat of which it is instantly converted into a thick vapour ; which, circulating through the furnace, enters the seggar through holes made in its side (the top being covered, to prevent the...
Σελίδα 39 - The principal quality of good enamel, and that which renders it fit for being applied on baked earthen ware, or on metals, is the facility with which it acquires lustre by a moderate heat, or cherry-red heat, more or less, according to the nature of the enamel, without entering into complete fusion. Enamels applied to earthen ware and metals possess this quality.
