PARAGUATAN

Volume 502 · 220 words · 1797 Edition

a kind of wood which grows in Guiana, and promises to be of great utility as a dye stuff. We have seen no botanical description of the tree; but from the report made to the Council of Trade and Mines, by D. Dominique Garcia Fernandez, Inspector of coinage, we learn that its bark, boiled in water, affords a coloured extract which resists the agency of acids for a longer time than brazil or logwood; that the colour may be revived by means of alkalies, after it has been destroyed by combination with acids; that vinegar, lemon-juice, and tartar, render this colour more brilliant, while they entirely destroy the colours of brazil and logwood; that the fecula of the bark of paraguatan fixes and attaches itself to wool, cotton, and silk; and that the colour is brighter on silk than on wool, and brighter on wool than on cotton. The same fecula dried is afterwards soluble in alcohol; to which it communicates a tinge similar to that afforded by cochineal; but it must be confessed, that the colour obtained from paraguatan has not the force of that of cochineal, though it is superior to those of madder, brazil wood, and logwood. From these facts D. Fernandez considers the paraguatan as one of the most valuable productions which America furnishes to Spain.
