notes:
|
The sugar cane juice flows from the mill to the factory where it is first heated and clarified, then condensed by boiling it into a thick syrup in which sugar crystals form. This mix is separated into sugar crystals and molasses by placing the mixture in upright conical pots. Over a period of days, or weeks, the molasses drains through a hole at the base of the cone, leaving a sugar loaf.A noted botantist, Velloso was appointed director of the press, Arco do Cego, incorporated in 1798 into the royal printing office. Meant to modernize the Portuguese empire, the Arco do Cego published at least 80 works in three years on various topics, including agriculture, navigation, and medicine.
