Sometimes the gilding of a piece failed, and had to be begun again, and there was endless trouble in saving the gold, as well as in preventing the workmen from stealing the amalgam. It was slow and troublesome work, and Marzio cared little for it, though his artistic instinct restrained him from allowing it to leave the workshop until it had been perfected to the highest degree.
As some flour-gold is here found, the cradle-bottom should be cut with cross-grooves to hold mercury; and the latter must be tempered with sodium or other amalgam. The cradle begat Long Tom and Broad Tom, the 'tom' proper being the upper box with a grating to keep out the pebbles.
This was done, when Tim flung about a pound of mercury into the cask, after which he dumped into it the black and yellow sand. As soon as the gold came in contact with the mercury it formed an amalgam. "This will do to start things," said Tim. "When we have enough to make it pay, we'll squaze it through a buckskin bag." "What is the result?"
At the end of this time the amalgam is run out through the stop-cock at bottom of the vat, is washed, and is put into hydraulic presses, by means of which the mercury is squeezed out, leaving behind a thick, pulpy mass, composed mainly of silver, and locally termed a "piña," from its resembling in shape the cone of a pine tree.
Now then, it's this sodium that I extract from salt water and with which I compose my electric cells." "Sodium?" "Yes, sir. Mixed with mercury, it forms an amalgam that takes the place of zinc in Bunsen cells. The mercury is never depleted. Only the sodium is consumed, and the sea itself gives me that.
This curious metal, quicksilver, or mercury, is fond of gold and hunts out every little bit, the two metals mixing together and making what is called an amalgam. This is heated in an iron vessel, and the quicksilver goes off in steam or vapor, leaving the gold free.
Squeeze the mercury through chamois skin. An amalgam, mostly gold, refuses to go through. Or apply heat. The mercury flies away as vapor and the gold remains. If thou seekest for wisdom as for silver, and searchest for her as for hid treasure, thou shalt find. A little boy had a silver mug that he prized very highly, as it was the gift of his grandfather.
This formation is intersected by numerous metalliferous veins, running, though irregularly, N.W. and S.E., and generally at right angles to the many dikes. The veins consist of native silver, of muriate of silver, an amalgam of silver, cobalt, antimony, and arsenic, generally embedded in sulphate of barytes.
And here precisely is that which constitutes the inflexible rigour of the calculus, the luminous certainty before which every cultivated mind is forced to bow. Algebra is the oracle of the absolute truth, because it reveals nothing but what the mind had hidden in it under an amalgam of symbols. We put 2 and 2 into the machine; the rollers work and show us 4. That is all.
Three months ago, when I set out to reduce my belt line and my collar size, I snatched the beam down ker-smack at two hundred and thirty-six pounds, stripped. This morning I weighed exactly one hundred and ninety-seven, including amalgam fillings and the rights of translation into foreign languages, including the Scandinavian. One hundred and eighty-five pounds is my ultimate aim.
