All sugars are colourless solids or syrups, which char on strong heating; they are soluble in water, forming sweet solutions but difficultly soluble in alcohol.
Nevertheless, it has been found in practice, when syrups with low quotient of purity and high quotient of impurity are being treated, injecting the feed at a number of different points in the pan does reduce the time required to boil the pan, though of no practical advantage with syrups of high quotient of purity and free from the viscosity which impedes circulation and therefore quick boiling.
In some factories for refining sugar made from beet or canes this system of carbonatation is used, and enables the refiner to work with syrups distinctly alkaline and to economize a notable amount of animal charcoal.
He graduated in arts, and claims to have graduated in medicine (of this there is no record at Paris), published six lectures on " syrups " (the most popular of his works), lectured on geometry and " astrology " (from a medical point of view) and defended by counsel a suit brought against him (March 1538) by the medical faculty on the ground of his astrological lectures.
Syruporum universa ratio, &c. (Paris, 1537); four subsequent editions; latest, Venice, 1548 (six lectures on digestion; syrups treated in fifth lecture).
Flavoured syrups are made by adding flavouring matter to a simple syrup. For instance, syrupus aromaticus is prepared by adding certain quantities of orange and cinnamon water to simple syrup. Similarly, medicated syrups are prepared by adding medicaments to, or dissolving them in, the simple syrup. Golden syrup is the uncrystallizable fluid drained off in the process of obtaining refined crystallized sugar.
Treacle and molasses are syrups obtained in the earlier stages of refining.
