fusibility

Fusibility is the ease with which a material will melt.

Its malleability decreases, and fusibility increases, with an increase in carbon.

On the other hand, firebricks used for furnace linings only melt at very high temperatures and so have low fusibility.

Further trials discover fusibility and fixedness.

Another adds to those qualities fusibility: and then the word gold signifies to him a body, bright, yellow, fusible, and very heavy.

My uncle Hardwigg was once known to classify six hundred different geological specimens by their weight, hardness, fusibility, sound, taste, and smell.

Other simple tools include the blowpipe (to test the fusibility of detached crystals), the goniometer, the magnet, the magnifying glass and the specific gravity balance.

For by what right is it that fusibility comes to be a part of the essence signified by the word gold, and solubility but a property of it?

This valuable metal possesses the whiteness of silver, the indestructibility of gold, the tenacity of iron, the fusibility of copper, the lightness of glass.

The location of the volcanism is governed by the stress field in the plate and the amount of melt is governed by the fusibility of the mantle beneath.

But yet it is its colour, weight, fusibility, fixedness, &c., which makes it to be gold, or gives it a right to that name, which is therefore its nominal essence.

Afterwards, with the spread of tin glazes, lead gradually became the principal background in tin glazes, though a small proportion of alkali was still introduced in order to increase the fusibility.

The idea of a triangle is made up from the ideas of being a closed figure, and having three straight sides; the idea of gold from those of yellowness, malleability, and fusibility.

Materials such as solder require a low melting point so that when heat is applied to a joint, the solder will melt before the materials being soldered melt, i.e. high fusibility.

Salt was the principle of fixity (non-action) and in-combustibility; mercury was the principle of fusibility (ability to melt and flow) and volatility; and sulfur was the principle of inflammability."

Because it is no consequence one way or the other from my complex idea: the necessity or inconsistence of malleability hath no visible connexion with the combination of that colour, weight, and fusibility in any body.

He would refer any mineral to its proper place among the six hundred [l] elementary substances now enumerated, by its fracture, its appearance, its hardness, its fusibility, its sonorousness, its smell, and its taste.

Because of their difficult fusibility, extremely low water content, and its chemical composition, the current overwhelming consensus among earth scientists is that moldavites were formed 15 million years ago during the impact of a giant meteorite in present-day Nördlinger Ries.

Whereby it is plain that men follow not exactly the patterns set them by nature, when they make their general ideas of substances; since there is no body to be found which has barely malleableness and fusibility in it, without other qualities as inseparable as those.

For fusibility being one of the simple ideas that goes to the making up the complex one the sound gold stands for, what can it be but playing with sounds, to affirm that of the name gold, which is comprehended in its received signification?

What I have said here of the nominal essence of gold, supposed to consist of a body of such a determinate colour, weight, and fusibility, will hold true, if malleableness, fixedness, and solubility in aqua regia be added to it.

The yellow shining colour makes gold to children; others add weight, malleableness, and fusibility; and others yet other qualities, which they find joined with that yellow colour, as constantly as its weight and fusibility.

(2) When it having a complex idea made up of such a collection of simple ones as nature never puts together, it judges it to agree to a species of creatures really existing; as when it joins the weight of tin to the colour, fusibility, and fixedness of gold.

Arabic and medieval alchemists believed that all metals, and in fact, all sublunar matter, were composed of the principle of sulfur, carrying the combustible property, and the principle of mercury, the mother of all metals and carrier of the liquidity or fusibility, and the volatility properties.

For, it is the real constitution of its insensible parts, on which depend all those properties of colour, weight, fusibility, fixedness, &c., which are to be found in it; which constitution we know not, and so, having no particular idea of, having no name that is the sign of it.
