Blowpipe   Listen
noun
Blowpipe  n.  
1.
A tube for directing a jet of air into a fire or into the flame of a lamp or candle, so as to concentrate the heat on some object. Note: It is called a mouth blowpipe when used with the mouth; but for both chemical and industrial purposes, it is often worked by a bellows or other contrivance. The common mouth blowpipe is a tapering tube with a very small orifice at the end to be inserted in the flame. The oxyhydrogen blowpipe, invented by Dr. Hare in 1801, is an instrument in which oxygen and hydrogen, taken from separate reservoirs, in the proportions of two volumes of hydrogen to one of oxygen, are burned in a jet, under pressure. It gives a heat that will consume the diamond, fuse platinum, and dissipate in vapor, or in gaseous forms, most known substances.
2.
A blowgun; a blowtube.
Blowpipe analysis (Chem.), analysis by means of the blowpipe.
Blowpipe reaction (Chem.), the characteristic behavior of a substance subjected to a test by means of the blowpipe.

... published results counter to those announced by Needham in 1748, and obtained by methods so precise as to completely overthrow the convictions based upon the labours of his predecessor. Charging his flasks with organic infusions, he sealed their necks with the blowpipe, subjected them in this condition to the heat of boiling water, and subsequently exposed them to temperatures favourable to the development of life. The infusions continued unchanged for months, and when the flasks were subsequently ...

... safe," she pointed out brightly. "It is not only proof against explosives, but between the plates is a lining that is proof against thermit and even that oxy-acetylene blowpipe by which you rescued me from the old boiler. It has a time lock, too, that will prevent its being opened at night, even if ...

... tribesmen were hunters and fishers. The majority were given to paint their bodies and to pierce their ears, noses, and lower lips, in order to insert reeds, feathers, and similar savage ornaments. In the more tropical forest regions the blowpipe constituted one of the most formidable weapons. Bows and arrows were in general use, the points of these latter being of bone or hardened wood. The barbs of the spears were similarly contrived, many of these weapons being beautifully decorated ...

... seldom a sixpence-worth of copper. Doctor Cacaphodel, the alchemist, returned to his laboratory with a prodigious fragment of granite, which he ground to powder, dissolved in acids, melted in the crucible and burnt with the blowpipe, and published the result of his experiments in one of the heaviest folios of the day. And for all these purposes the gem itself could not have answered better than the granite. The poet, by a somewhat similar mistake, made ...

In their preparation three articles are essential; first a three-square hard-steel file or preferably a glass-worker's knife of hard Thuringian steel for cutting glass tubes etc.; next a blowpipe flame, for although much can be done with the ordinary Bunsen burner, a blowpipe flame makes for rapid work; and lastly a ...

... devised for effecting a change of state in almost every known substance. Platinum, alumina, and rock crystal, it is true, cannot be liquified by the most intense heat of our furnaces, but they melt like wax before the flame of the oxy-hydrogen blowpipe. On the other hand, of the twenty-eight gaseous bodies with which we are acquainted, twenty-five may be reduced to a liquid state, and one into a solid. Probably, ere long, similar changes of condition will be extended to every form ...

... air, by measuring the proportion of oxygen, was discovered by Dr. Priestley. He lived and died in my native town, universally beloved as a man, and greatly admired as a philosopher. Chemistry has actively advanced among us during the present century. Hare's compound blowpipe came from his hand so perfect, in 1802, that all succeeding attempts of Dr. Clark, of England, and of all others, in Europe and America, to improve upon it or go beyond the effects produced, have wholly failed. His mode of mixing oxygen and hydrogen gases, the instant ...

The methods of chemical analysis may be classified according to the type of reaction: (1) dry or blowpipe analysis, which consists in an examination of the substance in the dry condition; this includes such tests as ignition in a tube, ignition on charcoal in the blowpipe flame, fusion with borax, microcosmic salt or fluxes, and flame colorations (in quantitative work the dry methods are sometimes termed "dry assaying"); (2) wet analysis, in which a solution of the substance is treated ...

It is infusible before the blowpipe. It becomes electrical by rubbing, and retains its electricity for several hours; but does not become electrical by heating. It occurs in alluvial soil, in the vicinity of rocks belonging to the secondary or floetz-trap formation, and imbedded in gneiss. ...

The natives brought me daily a few insects obtained at the Sagueir palms, including some fine Cetonias and stag-beetles. Two little boys were very expert with the blowpipe, and brought me a good many small birds, which they shot with pellets of clay. Among these was a pretty little flower-pecker of a new species (Prionochilus aureolimbatus), and several of the loveliest honeysuckers I had yet seen. ...

It was composed, in the usual way, by a mixture of sand or silex with alkalis, and, like the Egyptian, appears to have been first rudely fashioned into shape by the blowpipe. It was then more carefully shaped, and, where necessary, hollowed out by a turning machine, the Marks of which are sometimes still visible. The principal specimens which have been discovered are small bottles and bowls, the former not more than three or four inches high, the latter from ...

The point is then ground on a copper wheel of emery.
