Autoclaves, in which the materials are boiled under pressure, are also employed for certain soaps.
Suppose that a pure soap without resin is to be made - a product little seen in the market - the spent lye is run off, steam is again turned on, pure water or very weak lye run in, and the contents boiled up till the whole is thin, close and clear.
The spent lye of the washing being drained off, the soap is now " boiled for strength."
The solution is filtered off, boiled till free of sulphuretted hydrogen, and ammonium chloride and ammonia added.
In this case, the precipitate is dissolved in as little as possible hydrochloric acid and boiled with ammonium acetate, acetic acid and ferric chloride.
The white precipitate formed by cold hydrochloric acid is boiled with water, and the solution filtered while hot.
The solution is boiled till free from sulphuretted hydrogen and treated with excess of sodium hydrate.
Of nitrogen liberated; (2) by Will and Varrentrapp's method, in which the substance is heated with soda-lime, and the ammonia evolved is absorbed in hydrochloric acid, and thence precipitated as ammonium chlorplatinate or estimated volumetrically; or (3) by Kjeldahl's method, in which the substance is dissolved in concentrated sulphuric acid, potassium permanganate added, the liquid diluted and boiled with caustic soda, and the evolved ammonia absorbed in hydrochloric acid and estimated as in Will and Varrentrapp's method.
When boiled with calcium chloride and ammonia, salicylic acid gives a precipitate of insoluble basic calcium salicylate, C 6 H 4 ‹ 0 2 i Ca, a reaction which serves to distinguish it from the isomeric metaand para-hydroxybenzoic acids.
When boiled with aniline it gives methylaniline and phenol.
It is a pleasantsmelling liquid which boils at 233° C. It is practically unchanged when boiled with aniline.
In the Deuteronomist the lamb is to be sodden or boiled, whereas in the Priestly Code this is expressly forbidden.
A remarkable change occurs when many albumins are boiled with water, or treated with certain acids, their solubility and general characters being entirely altered, and the fluid becoming coagulated.
The juice, when not boiled down to form sugar, is either drunk fresh, or fermented and distilled to form arrack.
O, which, in turn, when boiled with a solution of boric acid, gives PbB407.4H20.
The filtrate, on being boiled down, yields a second crop of uranate.
One part of cream of tartar, two of alum and two of common salt are dissolved in boiling water, and the solution is boiled with granulated metallic tin (or, better, mixed with a little stannous chloride) to produce a tin solution; and into this the articles are put at a boiling heat.
The food of the people consists as a rule of boiled rice with salted fresh or dried fish, salt, sessamum-oil, chillies, onions, turmeric, boiled vegetables, and occasionally meat of some sort from elephant flesh down to smaller animals, fowls and almost everything except snakes, by way of condiment.
Salted fish forms, along with boiled rice, one of the chief articles of food among the Burmese; and as the price of salted fish is gradually rising along with the prosperity and purchasing power of the population, this industry is on a very sound basis.
By a change of temperature and pressure combined, a substance can in general be made to pass from one state into another; thus by gradually increasing the temperature a solid piece of ice can be melted into the liquid state of water, and the water again can be boiled off into the gaseous state as steam.
We may notice that the pentoses differ from other sugars by yielding furfurol when boiled with hydrochloric acid.
After the juice has been obtained, the leaves are sometimes boiled, so as to yield an inferior kind of aloes.
Another process consists in treating a mixture of the residue with one-quarter of its weight of calcined sodium sulphate with sulphuric acid, the residue being finally boiled with a large quantity of acid.

Evidently the idea of the great Yokoya experts, the originators of the style, was to break away from the somewhat formal monotony of ordinary engraving, where each line performs exactly the same function, and to convert the chisel into an artists i It is first boiled in a lye obtained by lixiviating wood ashes; it is next polished with charcoal powder; then immersed in plum vinegar and salt; then washed with weak lye and placed in a, tub of water to remove all traces of alkali, the final step being to digest in a boiling solution of copper sulphate, verdigris and water.
When boiled with alkaline carbonates it is converted into strontium carbonate.
The solution, if boiled, deposits its titanic oxide as a hydrate called metatitanic acid, TiO(OH) 21 because it differs in its properties from orthotitanic acid, Ti(OH) 4, obtained by decomposing a solution of the chloride in cold water with alkalis.
The solution when boiled deposits most of its oxide in the meta-hydrate form.
