Vitrified cairns also occur in the Orkney Islands, notably on the little isle of Sanday, but the most interesting structures of the kind are Craig Phoedrick and Ord Hill of Kissock, which rise up like huge pillars on the hills at the entrance of Moray Firth, at a distance of three miles from each other.
On the third day from the commencement of the operation, all the tubes were taken out, the ends of many of them being vitrified with the heat; but the metal was not removed until some days afterwards, when the whole was perfectly cool. Part of the furnace was then taken down, and the iron appeared in the form of a large irregular mass, with pieces of charcoal adhering to it.
Some means of fixing colour so that it should not be washed away by the first rain was sought, and it was found in the invention of enamel, in the coating of the bricks with a coloured material that when passed with them through the fire would be vitrified and would sink to some extent into their substance.
The only buildings or structures existing in Cat in Pictish and early Norse times were a few vitrified forts, some underground erde-houses, hut-circles innumerable, and perhaps a hundred and fifty brochs, or Pictish towers as they are popularly called, which had been erected at various dates from the first century onwards, long before the advent of the Norse Vikings is on record, as defences against wolves and raiders both by land and sea, and especially by sea.
He ran it up eight stories high, however, and two of them still stand, at this day a colossal mass of brickwork, rent down the centre by earthquakes, and seared and vitrified by the lightnings of an angry God. But the vast ruin will still stand for ages, to shame the puny labors of these modern generations of men.
Before you have solved their mysteries, this earth where you first saw them may be a vitrified slag, or a vapor diffused through the planetary spaces. Mysteries are common enough, at any rate, whatever the boys in Roxbury and Dorchester think of "brickbats" and the spawn of creatures that live in roadside puddles.
Wherever these liquid masses, melted by a heat more intense than can be produced by any artificial means, have flowed over them or cooled in immediate contact with them, the clays will be changed to slate, the limestone will have assumed a character more like marble, while the sandstones will be vitrified.
The Keramic Museum of Sevres contains several specimens which present very notable differences to each other. Those from Chateau-Gontier are formed of very close-grained quartzite granite of a greenish color streaked with black. The conglomerate welding there together is a vitrified scoria full of very small bubbles made by the escape of gas which had not had sufficient strength to get out.
The incineration and fusion of the materials of which the vitrified forts are made, especially the granite ones of La Creuse and the Cotes du Nord, bear witness, says Daubree, to a surprising skill and knowledge of the management of fire in those who burned them, but these qualities were manifested also in extremely ancient metallurgical operations.
