The muffle being charged, its mouth is closed with a fire-tile well luted round its edges.
When the muffle has attained to a white-red heat, the sheet iron tray, bearing its enamel plate, is to be introduced with a pair of pincers into the front of the muffle, and gradually advanced towards its further end.
Great care must be taken that the heat thus applied by the muffle furnace be very equable, for otherwise wreathes might be very readily re-produced in the discs.
The muffle must be made of very refractory fire-clay, flat at its bottom, and only 5 or 6 inches high, with such an arched top as may make the roof strong, and so close on all sides as to exclude entirely the smoke and flame.
Soon after the fire is lighted, the flame, which communicates laterally from one furnace to another, envelopes the muffle on all sides, and thence rises up the chimney.
With this view the air must have free entrance, and the front aperture of the muffle must be left quite open.
The muffle is made of earthenware, and as thin as possible.
The mouth of the muffle is to be then closed with two pieces of charcoal only, between which the artist may see the progress of the operation.
It is then to be passed through the muffle kiln; but it requires a second application of the platinum to have a sufficient body of lustre.
In front of this opening, is the table or shelf, upon which the door of the muffle is made to advance or recede; the letter q, fig.
The articles which are printed or painted upon the glaze are placed in the muffle without saggers, upon tripods, or movable supports furnished with feet.
George reported that we had the outlaws located, and the Lieutenant gave orders for the soldiers to muffletheir spurs and sabres and to be quick about it.
He then gave orders for all of the men to muffle their spurs, and he asked me to take my four men and as soon as the charge was made to make a dash for the horses, cut them off and stampede them.
The glaze and the enamel colours were both melted by the heat in the muffle kiln, but the body was not affected.
The decoration was often fixed in the "petit feu," ormuffle kiln.
More delicate enamel colours were applied for firing in the "petit feu" or muffle kiln.
The muffle furnace is used for hardening dies, taps, cutters and similar tools of either carbon or high-speed steel.
The heating for forging should be done preferably in a pipe or muffle furnace, but if this is not convenient use a good clean fire with plenty of fuel between the blast pipe and the tool.
The heating for forging should be done preferably in a pipe or muffle furnace but if this is not convenient use a good clean fire with plenty of fuel between the blast pipe and the tool.
Hold the steel at this temperature until the heat has thoroughly saturated through the metal, then allow the muffle box and tools to cool very slowly in a dying furnace or remove the muffle with its charge and bury in hot ashes or lime.
Until the temperature of the muffle reaches about 1,300°F.
The ordinary hardening room equipment should consist of: Gas or oil muffle furnace for hardening.
If a forge is not at hand and heating must be done, use a muffle furnace and cover small shanks with a paste from fire clay or ground asbestos.
The muffle furnace is for spring hardening, enameling, assaying and work where the gases of combustion may have an injurious effect on the material.
The dried glass is finally heated to a temperature of dull redness in a muffle furnace.

Outside, in a well-built lean-to, was the muffle kiln for onglaze and lustre decoration.
Small muffle kiln--oil or gas--for over-glaze and lustres.
An ideal muffle of this kind would be one with flues all round, gradual access of flame on all sides, spy holes each end, and the top to lift off, for placing.
Any crack in the muffle should be well stopped and lime may be used to neutralize the effects of any sulphur that may enter.
This renders the muffle less liable to absorb glaze from the pots in glost firing.
In firing with a muffle kiln the introduction of coal-gas free from sulphur is a matter attended with some risk at the necessarily low temperatures required by the lustres.
Trials are always useful but they must be small and easily hooked out, as constant poking about at the spy hole lowers the temperature of the muffle at the front, just where it is most difficult to get it up.
Colour will begin to show inside the muffle about the fifth or sixth hour, and the top dampers can come out a little, the front one more than the back, to draw the flame towards the door.
The muffle construction and the burner arrangements are ingenious and practical, and need little manipulation to insure even distribution of heat.
When the eight burners have been on about one and one half hours the muffle will probably show a dull red inside and all danger of blowing will be passed.
The flames play all round the muffle or fire-clay box during the firing, but no flame or fume is allowed access to the inside.
The flames strike the bottom of the muffle and pass up through fire-clay pipes, which project into the muffle, then pass off through a twin flue regulated by dampers.
Extinguish the gas, and when the mufflehas become quite cold remove the filter candles, and store them (without removing the asbestos wrappings) in sterile metal boxes.
Light the gas and raise the contents of the muffle to a white heat; maintain this temperature for five minutes.
Muffle furnace (for the sterilisation of filter candles, and for the destruction of morbid tissues).
Then let it cool, beat it very fine, and roast it a second time, keeping it under themuffle till it emit no more smell.
Break into small bits the Black Copper you intend to purify; mix therewith a third part in weight of granulated Lead, and put the whole into a cupel set under the muffle in a cupelling furnace, and previously heated quite red.
The Muffle must be placed on these bars in the fire-place in such a manner that its open end shall stand next to, and directly against the door of the fire-place, and may be joined to it with lute.
Take a cupel capable of containing one third more matter than you have to put into it: set it under the muffle of a furnace, like that described in our Theoretical Elements, as peculiarly appropriated to this sort of operation.
Pound into a coarse powder the martial stones or earths out of which you design to extract the Iron: roast this powder in a test under the muffle for some minutes, and let your fire be brisk.
The Muffle being thus constructed, and then well baked, is fit for use.
If you desire to separate it entirely therefrom, you must put it into a cupel, and expose it under the muffle to such a degree of fire as may convert all the Lead into litharge.
Place the test thus loaded under the further end of the muffle in a cupelling furnace.

Upper lip cleft; the muffle small and naked; tail cylindrical, sometimes hairy, but commonly covered with scales arranged in rings.
Toward eleven o’clock he was so much worse that it was found necessary to muffle the stable knocker.
The shape of the bore of the muffle should always conform to that of the article tempered; for round work, a round muffle; for square work, a square one; and so on.
It is obvious that if the muffle is heated evenly the steel will temper most evenly by being held in the centre of the muffle, or the piece may be revolved and moved endways in the muffle in order that the steel may heat evenly.
Where tempering is carried on continuously the muffle is kept in the fire, although it is claimed by many that better results are obtained by removing it from the fire when heated.
A muffle is a tube or cylinder receiving its heat from the outside and open at the end or ends to receive the steel.
The muffle should be shorter than the work, so that the tempering of either end of the work may be retarded, if it is proceeding too fast, by allowing that end to protrude through the muffle.
The muffle should therefore bear such a proportion in size that when heated to a blood red, and taken from the fire, its temperature will be reduced to nearly that of the steel when it has acquired its proper degree of temper.
The muffle is not naked for the greater part, though the shortness of the hairs gives that effect.
A muffle furnace, employed for annealing, hardening and tempering is shown in fig.
This passes into the furnace through the two holes, C, C, and plays under and up around the muffle D, standing on a fireclay slab.
