Of zinc, all the gold and copper and some silver and lead will be alloyed with the zinc to a so-called gold - or copper - crust, and the residual lead saturated with zinc. By removing from the surface of the lead this first crust and working it up separately (liquating, retorting and cupelling), dore silver is obtained.
The learned hold the doctrine of Confucius, and Buddhism, alloyed with much popular superstition, has some influence.
A sheet iron case is then placed within the furnace, and the space between it and the walls rammed with limed charcoal; the interior is filled with fragments of the iron or copper to be alloyed, mixed with alumina and coarse charcoal, broken pieces of carbon being placed in position to connect the electrodes.
This is so when gold and silver are alloyed with each other, and is true in the case of alloys of copper.
Neville proved that when one metal is alloyed with a small quantity of some other metal, the solidification obeys the law of F.
Alloyed with copper, it is used for the envelopes of bullets.
Manganese not only forms with iron several alloys of great interest, but alloyed with copper it is used for electrical purposes, as an alloy can thus be obtained with an electrical resistance that does not alter with change of temperature; this alloy, called manganin, is used in the construction of resistance-boxes.
Titanium is alloyed in small quantities with aluminium for use in naval architecture.
Aluminium, when alloyed with a few per cent of magnesium, gains greatly in rigidity while remaining very light; this alloy, under the name of magnalium, is coming into use for small articles in which lightness and rigidity have to be combined.
- Alchorne showed that gold alloyed with th part of tin is sufficiently ductile to be rolled and stamped into coin, provided the metal is not annealed at a high temperature.
Graham showed that a wire of palladium alloyed with from 24 to 25 parts of gold does not exhibit the remarkable retraction which, in pure palladium, attends its loss of occluded hydrogen.
- Gold alloyed with 4th or 1th of rhodium is, according to Wollaston,very ductile,infusible and of the colour of gold.
- Small quantities of iridium do not destroy the ductility of gold, but this is probably because the metal is only disseminated through the mass, and not alloyed, as it falls to the bottom of the crucible in which the gold is fused.
Its striking characteristics are: (1) that for given metals alloyed together its composition is fixed, and does not vary with the proportions in which those metals are present, because any " excess metal," i.e.
Coptic, much alloyed with Arabic, was spoken in Upper Egypt as late as the 15th century, but it has long been a dead language.
It occurs in the uncombined condition and alloyed with iron in meteorites; as sulphide in millerite and nickel blende, as arsenide in niccolite and cloanthite, and frequently in combination with arsenic and antimony in the form of complex sulphides.
The Pimas and Papagoes were early converted by the Spaniards, and retain to-day a smattering of Christianity plentifully alloyed with paganism.
Copper, gold alloyed with platinum, iron ore, barytes, graphite and lead occur in small quantities in the state.
