16.22 CHAP. 22.—METHODS BY WHICH THICK PITCH IS PREPARED.

The liquid that follows is of a thicker consistency, and constitutes pitch, properly so called. This liquid, thrown again into a brazen cauldron, and mixed with vinegar, becomes still [Note] thicker, and when left to coagulate, receives the name of "Bruttian" [Note] pitch. It is used, however, only for pitching the insides of dolia [Note] and other vessels, it differing from the other kinds in being more viscous, of a redder colour, and more unctuous than is usually the case. All these varieties of pitch are prepared from the pitch-tree, by putting red-hot stones, with the resinous wood, in troughs made of strong oak; or if these troughs are not attainable, by piling up billets of the

wood in the method employed for the manufacture of charcoal. [Note] It is this pitch that is used for seasoning wine, being first pounded and reduced to a fine powder: it is of a blacker colour, too, than the other sort. The same resin, if boiled gently with water, and then strained off, becomes viscous, and assumes a red colour; it is then known as "distilled" [Note] pitch:" for making this, the refuse portions of the resin and the bark of the tree are generally selected.

Another method is adopted for the manufacture of that used as crapula. [Note] Raw flower of resin is taken, direct from the tree, with a plentiful sprinkling of small, thin chips of the wood. These are then pounded [Note] down and passed through a sieve, after which they are steeped in water, which is heated till it comes to a boil. The unctuous portion that is extracted from this is the best resin: it is but rarely to be met with, and then only in a few places in Italy, in the vicinity of the Alps: it is in considerable request for medicinal purposes. For this, they generally boil a congius of white resin to two congii of rain-water: [Note] some persons, however, think it better [Note] to boil it without water for one whole day by a slow fire, taking care to use a vessel of white copper. [Note] Some, again, are in the habit of boiling the resin of the terebinth [Note] in a flat pan [Note] placed upon hot ashes, and prefer it to any other kind. The resin of the mastich [Note] is held in the next degree of estimation. [Note]
