This clay is fusible at a strong heat, in consequence of the iron and lime which it contains.
This may be accomplished by filling them with fusible metal, and dissolving the substance of the shell by muriatic acid; thus a metallic solid will remain which exactly filled all the cavities.

We have also the description of a smaller furnace, which is perhaps that in which the more fusible glass for enamels and minor objects of verroterie was melted.
The Romans and the Byzantine Greeks, it is true, decorated their glass at times with thin washes of opaque paints, but we have no definite proof that they ever applied fusible lead enamels in this way.
But this was an enameller's process, and the coating must have consisted of a somewhat fusible glass, perhaps containing lead.
Greeks decorate the glass cups made from 'sapphire stones' with gold and silver leaf, covering the foil with a layer of very fusible colourless enamel.

The smoke thus produced reduces the red ferric oxide to blue-green ferrous oxide, or to metallic iron, which combines with the silica present to form a fusible ferrous silicate.
The product obtained by adding tin to copper is more fusible than copper and thus better suited for casting; it is also harder and less malleable.
Although fusible plugs may be used, in addition to other means of insuring safety, they ought not to be exclusively relied on at the ordinary working pressure of the boiler.
The fusibleplug ought to be capable of more than resisting the pressure; but if it be so, its point of fusion would be one at which the steam would have a pressure of at least two atmospheres above its working pressure.
Various alloys of metal are fusible at temperatures sufficiently low for this purpose.
The paste of which they are made is very fine and homogeneous, coated with a peculiar glassy lustre, which is thin but tenacious, red or black, and formed of silica rendered fusible by an alkali.
All this caused me such labour and heaviness of spirit, that before I could render my enamels fusible at the same degrees of heat, I verily thought I should be at the door of my sepulchre.
To determine the actual temperature of the calcium carbide itself, he scattered amongst the carbide charge fragments of different fusible metallic alloys which were known to melt or soften at certain different temperatures.
This may be ascertained by placing short lengths of wire, drawn from fusible metal, in those parts of the apparatus in which heat is liable to be generated.

By sub-dividing the metal, increased radiating surface is obtained which permits a reduction in the volume offusible metal necessary, and the metal vapor formed when the fuse blows on heavy overload is more readily dissipated.

Generally, a spelter of different composition is required for iron, copper, and brass work, that for the latter being required more readily fusible than that for the former.
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.
