These patterns he first scratched on the outer surface of the vessel with a graving tool; then, when he had made his depressions deep enough, he took threads of coloured glass, and having filled up with the threads the depressions which he had made, he subjected the vessel once more to such a heat that the threads were fused, and attached themselves to the ground on which they had been laid.

In melting they would generally more than fill the cavities, overflowing them, and protruding from them, whence it was for the most part necessary to repeat the polishing process, and to bring by means of abrasion the entire surface once more into uniformity.

There are cases where this has been incompletely done and where the patterns project; there are others where the threads have never thoroughly melted into the ground, and where in the course of time they have partially detached themselves from it; but in general the fusion and subsequent polishing have been all that could be wished, and the patterns are perfectly level with the ground and seem one with it.[846] The running of liquid glass into moulds, so common nowadays, does not seem to have been practised by the Phoenicians, perhaps because their furnaces were not sufficiently hot to produce complete liquefaction.
But--if this was so--the pressure of the viscous material into moulds cannot have been unknown, since we have evidence of the existence of moulds,[847] and there are cases where several specimens of an object have evidently issued from a single matrix.[848] Beads, cylinders, pendants, scarabs, amulets, were probably, all of them, made in this way, sometimes in translucent, sometimes in semi-opaque glass, as perhaps were also the _plaques_ which have been already described.
The ceramic art of the Phoenicians is not very remarkable.

Phoenicia Proper is deficient in clay of a superior character, and it was probably a very ordinary and coarse kind of pottery that the Phoenician merchants of early times exported regularly in their trading voyages, both inside and outside the Mediterranean.

We hear of their carrying this cheap earthenware northwards to the Cassiterides or Scilly Islands,[849] and southwards to the isle of Cerne, which is probably Arguin, on the West African coast;[850] nor can we doubt that they supplied it also to the uncivilised races of the Mediterranean--the Illyrians, Ligurians, Sicels, Sards, Corsicans, Spaniards, Libyans.
