Sheet iron and sheets made from alloy iron coated with spelter have been extensively used and seem to be durable, especially when laid deep enough to eliminate possibility of damage from heavy loads.
When I got back to my shanty after taking in my traps, I found that two men had been there stealing my spelter that I have worked hard for.
Then I will pack my spelter on my horse and go to the nighest post--it is just a jump from here--and trade it off for provisions.
The molten spelter will penetrate between surfaces that water will flow between when the work and spelter have both been brought to the proper heat.
The heat should be continued only long enough to cause the spelter to flow into place and no longer.
The hardest grade of spelter is made from three-fourths copper with one-fourth zinc and is used for working on malleable and cast iron and for steel.
By distributing the spelter at the proper points along the rod it may be placed at the right points by turning the rod over after inserting into the recess.
In case it is necessary to braze on the inside of a tube or any deep recess, the spelter may be placed on a flat rod long enough to reach to the farthest point.
This hard spelter melts at about 1650° and is correspondingly difficult to handle.
Brazing is done by clamping the work in the jaws and heating until the flux, then the spelterhas melted and run into the joint.
Spelter is variously composed of alloys containing copper, zinc, tin and antimony, the mixture employed depending on the work to be done.
Spelter is then placed in such a position that it will run into the joint and the heat is continued or increased until the spelter melts and flows in between the two surfaces.
If the spelter melts into small globules in place of flowing, it may be caused to spread and run into the joint by lightly tapping the work.
If the cleaning and distribution of flux has been successful, the spelter will "run" along the joint very freely, and the work should be tapped gently to make sure that the spelter has really run into the joint.
Soldering at a red heat by means of spelter is called brazing.
Spelter tends to run very freely when it melts, and if the brass surface in the neighbourhood of the joint is at all clean, may run where it is not wanted.
Care must be taken to place the spelter on those parts only which are intended to receive it, and when this is done, the joint may be lightly powdered over with the dry borax, and will then be ready for heating.
In the first place, spelter is merely rather soft brass, and consequently it often cannot be fused without endangering the rest of the work.
The next step is to prepare the spelter, and this is easily done by mixing it with the cream, taking care to stir thoroughly with a flattened iron wire till each particle ofspelter is perfectly covered with the borax.
In fact all the processes there described may be applied equally to the case under discussion, the substitution of silver for spelter being the only variation.
The heating may be interrupted when the spelter is observed to have melted into a continuous mass.
The temperature is gradually raised to a bright red heat, when the spelter will be observed to fuse or "run," as it is technically said to do.
This process resembles that last described, but instead of spelter an alloy of silver, copper, and zinc is employed.
Of course some control may be exercised by "soiling" with fireclay or using an oxidising flame; but the erratic behaviour of spelter in this respect is the greatest drawback to its use in apparatus construction.
Spelter is soft brass, and is generally made from zinc one part, copper one part; an alloy easily granulated at a red heat; it is purchased in the granular form.
Spelter or zinc is employed by jewellers in the manufacture of bright gold alloys, as it gives liveliness of colour to their wares not to be equalled by any other metal.
We have used copper and spelter in our silver solders, because we have found from experience that the fewer number of times a solder is melted the better it is for all purposes.
I will not give Mrs. Whiston's admirable reply; for Mr. Spelter informs me that you will not accept an article, if it should make more than seventy or eighty printed pages.
Mr. Spelter told me that his State exchanges showed that there had been difficulties of the same kind in all the other counties.
The hard solders are the spelterand the silver solders.
For brazed joints, spelter or powdered brass is employed, and the flux is usually borax.
The fused borax works its way in by capillary action, and the spelter follows.
The pipe is suspended vertically, flange downwards, and the spelter run in from the back of the flange.
Soft spelter solder is composed of equal parts of copper and zinc, melted and granulated and passed through a sieve.
They were first of iron and afterwards were generally of spelter or aluminium.
This, however, can only be taken advantage of when the particular variety of machine, with spelter male and female blocks, was available.
Zinc ore, from which spelter is obtained, reached the price of $112 a ton.
A suitable spelterfor ironwork is one composed of 2 parts copper and 1 part zinc; a spelter for copper consists of 3 parts copper and 2 parts zinc; while equal parts of copper and zinc make a suitable spelter for ordinary brass work.
Also, when a deep, wide joint is being dealt with, he finds it an advantage to smear on a little clay underneath and the side, as should the joint get slightly hotter in one part the spelter will run through and make an unsound joint.
Gently heat the article by some suitable means, such as foot bellows and blowpipe, so that it will expand equally, and not disarrange the seam; increase the temperature until the metal is a dull red, and the spelter runs.
Brazing is hard-soldering with spelter (brass), and a forge or a heavy blowlamp or a powerful blowpipe must be employed to provide the heat.
The heat required to braze cast-iron varies somewhat with thespelter used.
Then apply the flux andspelter and increase the heat.
A mixture of borax and water and spelter should now be applied to the joint, which should rest on a small heap of broken coke, the coke being also built round it.
A hard spelter should be used in preference to a readily fusible one, otherwise the spelter would be fused much too soon, and before the casting is raised to a sufficiently high temperature.
Spelter is in the form of filings, a thin stick, or wire.
In brazing, one of the conditions essential to success is that the metal to be brazed and the spelter should unite to form an alloy just where the brazing occurs, and that this should take place spontaneously.
A mixture of borax and water and spelter should now be applied where the brazing is required, and gentle heat then brought to bear on it until the water is evaporated.
After applying flux and spelter to the previously cleaned metal, direct the flame of the lamp on it, gently at first, until the spelter fuses and makes the joint.
She threw back her shawl from her head, and under the low-burning gas-light held aloft by the spelter statuette in the newel post, she confronted Mr. Dickerson.
A scarf, knotted and held by a spelter vase to one of the marble mantles, for there were two, recorded a moment of the æsthetic craze which had ceased before it got farther amidst the earlier and honester ugliness of the room.
It war no light load them hosses had to carry, fur our spelter war a'most as heavy as we war.
We had better shoulder our spelter an' be off to onct.
Thar war five of us in the party, an' as every man knowed his own bisness, by the time spring come we had as much spelter as four hosses could pack away.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "spelter" in a variety of sentences. We hope that you will now be able to make sentences using this word.
