The application of the principles of jewellery to the smaller as well as the larger blocks, will suggest to us another reason for the method of incrustation adopted in the walls.
After a time this matter hardens and forms a thick incrustation over the sores.
The salts usually responsible for such incrustation are the carbonates and sulphates of lime and magnesia, and boiler feed treatment in general deals with the getting rid of these salts more or less completely.
On the other hand, the decrease in capacity and efficiency accompanying an increased incrustation of boilers in use has been too generally discussed to need repetition here.
Circulation of water will not prevent incrustation altogether, but it lessens the amount in all waters, and almost entirely so in some, thus adding greatly to the efficiency of the surface.
It is said that an incrustation of only one-eighth inch will cause a loss of 25 per cent in efficiency, and this is probably within the truth in many cases.
This incrustation becomes very serious sometimes, so much so as to almost entirely prevent the transmission of heat from the metal to the water.
This exudation and the incrustation are especially common where the hairs are long, thick, and numerous, as in the region of the pastern of heavy draft horses.
I have shown specimens of this incrustation to several geologists, and they all thought that they were of volcanic or igneous origin!
I looked at it for some moments, for it was certainly a beautiful piece of work, with a wealth of inlay and incrustation little short of marvellous.
An incrustation on the interior of wine bottles, the result of the ripening of the wine; a deposit of tartar, etc.
There are just two distinct views under which we may consider all stalactical concretions formed; these are the incrustation of the calcareous substance concreting upon a foreign body, and the incrustation of the same substance upon itself.
Chilled through, with my clothing thoroughly saturated, I lay down under a tree upon the heated incrustation until completely warmed.
The approach to them was unsafe, theincrustation surrounding them bending in many places beneath our weight,--and from the fractures thus created would ooze a sulphury slime of the consistency of mucilage.
At the base of the turret lies a large petrified pine log, covered with a brilliantincrustation several inches thick.
As one of our company was unconcernedly passing near the brink, the incrustation suddenly sloughed off beneath his feet.
Besides the injury arising from the deposition of salt and the incrustation on the inner surface of boilers, an evil of a formidable kind attends the accumulation of soot mixed with salt in the flues, which proceeds from the leaks.
One of the remedies proposed for the evil consequences arising from incrustation is the substitution of copper for iron boilers.
The coating of the inner surface of a boiler by incrustation and the collection of salt sediment in its lower parts, are attended with effects highly injurious to the materials of the boiler.
This incrustation has all the characters of shell, displaying a highly polished surface, beautifully iridescent, and, when broken, a foliated texture.
Such an incrustation takes place on both the outside and inside of the wheel in a bleaching establishment, in which cotton cloth is rinsed free of the lime employed in its purification.
Borax is valuable, but occurring as it does as an incrustation upon the ground over large areas, a detailed description would be superfluous, as the explorer will surely recognize it should he find it.
Treat the suspected lead ore the same way, and you will get a yellow incrustation on the coal and a button of malleable lead.
A white incrustationon the coal, and a brittle button of antimony should be the result.
A globule of metal should result, and perhaps an incrustation on the coal.
Proceed as above, and after blowing for a few seconds moisten the incrustation with a drop of nitrate of cobalt.
Decorative pilasters flush with the wall are employed in the marble incrustation of S.
This, known as theIncrustation Style, aimed to imitate in stucco the appearance of a wall veneered with colored marbles.
The Incrustation Style, as previously remarked, left no place for paintings upon the walls.
In view of all the circumstances, we are probably safe in concluding that the Incrustation Style originated in Alexandria, in the third century B.
The dado in the Incrustation Style is generally treated as a separate member; in rare instances the imitation of marble blocks is extended to the floor.
Delos, remains ofIncrustation Style on island of, 461.
A metallic globule with or without an incrustation may be obtained.
A warm thick solution of glue should be spread upon the incrustation covering the bronze.
The eyes should be protected when using the hammer, whether on the incrustation or on the glue.
Various attempts have been made to remove the incrustation by raising the bronze to a red heat.
The first in this category represents the ultimate stage of decomposition of bronze and forms the outer incrustation of the statuettes.
The frequent use of these reagents is, however, strongly to be deprecated, for it is impossible to remove the acid by simple washing with water after the incrustation has been removed.
Large iron objects with a strong and firmly attached incrustation of rust will require a repetition of the process.
I found an abundance of the salineincrustation of which you have spoken, and at the time of my first visit there was a little pond hole just east of the point named that was in the act of drying up.
Common on pebbles, often covering their whole surface with a lace-like incrustation of very small oblong cells having a three-lobed aperture.
The layers are thin, but eventually overlap one another, and the incrustation sometimes becomes an inch thick and resembles coral.
