The works of the highly experienced and famous chymist, John Rudolph Glauber

by Johann Rudolf Glauber

NB. This is to be observed in this place, when the best and first Juice or Extraction is drawn out of the Vessel by a Tap, and fresh boiling water poured a second time on the malt in the Copper, and again drawn off by the Tap, those two waters in which the chiefest Virtue of the malt is, may be boiled and thickened by little and little in a plain or flat Copper. The third and fourth pouring on are indeed as yet good, but yet not fat enough, and seeing they are not very strong, are not worth the boiling away, for they won’t quit the costs of the Fire, and therefore are to be applied to some other uses. Now when a man is about this work, he may so order his boilings, as to have several of them one after another; and then those pourings on, viz. the second and third, remaining of the first course of boiling may be poured on the second course of boiling, in the stead of bare water: And so is it to be handled, that alwaies the first and second pouring on (and which contain in them the chiefest Virtues of the malt) may be boiled to the consistency of Honey in a Copper made for that purpose, of Evaporation; and the third and fourth pouring on may be alwaies kept for the next following course of boiling, and be poured on the malt in the room of bare water, and so are to be condensed by evaporation in a Copper, as the first and second pouring on were done withal in the first course of the boiling; and so always the 3d. and 4th. pouring on of the former course of boiling, is to be the first and second in the next following course of boiling; and this way of proceeding draws out of the malt its best and chiefest Virtues, and lessens the charge of the boiling: For the Costs would be far greater, if the third and fourth pouring on were to be boiled off per se.

NB. The Coppers and Pans necessary for the thus reducing these extracted Juices to the consistency of Honey, are already described, where mention is made of the Concentration of Wines. He that can’t well enough understand me, may take the pains to come and see my Furnaces, Coppers, and other Instruments appertaining to this work; as likewise the manual Operation, for I cannot help him any other way. And as for a larger description of these things, my time will not permit me at this instant to make it. The Juices being condensate, are to be drawn out of the Copper by a Tap fastened therein, or laved out, and being cool, put them up in Barrels, and shut them up tight, that the external air may not get thereinto; for thus may you keep them uncorrupt, even as long as you please.

NB. In your boiling them you must be very diligent that the Juices be not burnt to, by the overmuchness of your Fire, or that by being heat too hot, they boil not over; all which may be prevented by Registers (as the Chymists call them) destinated for the regulating of the Fire. This is a most compendious way of extracting the Virtues out of Corn, and of reducing them into a narrow room, the which if you order according to Art, that nothing of your Juices be spilt or lost, 8 Barrels of Malt will yield you one full of Juice, and which contains all the Virtues that were in those eight Barrels; the residue serves to fatten Beasts withal.

NB. He who knows how to convert those remains to his use, in another kind of way will do better, and extract thereoutof so much as he is constrained to lay out in buying his Corn, insomuch that he can have his Juices as it were even gratis. But of these things more hereafter.

As touching these Juices, they comprehend in them the whole Virtue of the Corn, out of which you may when you please boil Ale, make Adust or Brandy-wine or bake spiced Cakes; for if it be used to them instead of Honey, it makes them much the sweeter. These Juices therefore are to be prepared in those places in which Corn is sold at a very mean rate, and which cannot be exported to foreign parts, and is there in such great plenty, as that the Country-men know not what to do therewith, but there it lies in great Stacks and rots. Farther, they are yet prepared with greater benefit and more gain where the plenty and cheapness of wood is, the which yields no small encrease and addition to the Gains.

But that the nature and condition of this Labour may be the better understood, the following Computation will shew. Suppose I take 8 Barrels full of Corn and bring them into Malt, then boil it into Ale after the aforesaid way, and condense it into a Juice, wherewithal I fill one Barrel: This one Barrel now is far more commodious to be carried into foreign places either by Waggon or by Ship, than those 8 barrels, and will bring me double or treble the profit that 8 Medimni (a Measure containing some six bushels, or the eight barrels) of Corn. Why? because the greatest labour is already over, and there remains but very little to boil the Ale out of the Juice, as the following Example will demonstrate.

I buy me eight barrels in that place where Corn and Wood are to be had at a mean rate, and there passeth some River or other by the place, as the Mhene in Franconia, Nicer in Suevia, Visurgis in Hassia, and the Dukedome of Brunswick, Albis in Saxony and Misnia; for in all these places there is abundance of Corn, and store of Wood, and the price of each, mean enough in conscience. If now one Medimnus (or six bushels) of Corn be esteemed at the price of one Imperial, eight Medimni will yield eight Imperials; the Wood will cost one Imperial, the Labour one Florin: The juice out of the 8 barrels of Corn may be put in a Fir-Cask, as they use to do with Honey, that so in paying the carriage, it may not be accompted for Wine or Ale, but some dry Goods, and so valued by the hundred, as other dry Wares are priced; so then the Barrel will cost the Carriage by Water to some of the Maritine or Sea-coast Cities, two Florins. Now if we sum up all these Expences upon the Corn, Carriage, Fire, and Labour, they come to 12 Florins or 8 Imperials. But now, out of that one Barrel of Juice there may be made eight Barrels of the best Ale, and if you will have it somewhat smaller, then ’twill make 10 or 12, according as you boil your Ale to a stronger or weaker degree. However, this is certain, that one Barrel of Corn will yield more than a Barrel of good Ale; so that out of one Barrel of Corn may be made one and an half of strong Ale. Now then, if one of those Barrels of Ale yield three Imperials, the eight Barrels, which cost the buying, and reducing into one Barrel, and the transporting it, eight Imperials, may there be sold for 24 Imperials; from which the eight being subtracted, the remainder of the Gains is 16 Imperials, which verily is enough upon those 8 Barrels.

But put case the Corn were dearer, and the Carriage of the Juices to those places did cost more, and that those 8 Barrels of Corn, or one Barrel of Juice, did yield (besides all the costs) only 8 Imperials profit, yet would this be profit enough, and may well content a Man. I forbear to mention the other benefits and profits arising over and above besides this Gains; for by this kind of way is saved and made vendible that Corn which would else be spoiled: Besides in a plentiful time the mean-prized Corn may be bought up, concentrated and kept till a scarcity come. Nor is there any cause of fear that it will be devoured by the Mice and Rats, or be spoiled with lying, or wax mouldy, or be any other way corrupted.

Nay more, it occupies less room than the Corn would; for where one Barrel of Juice lies, there should have lain eight Barrels of Corn.

Besides, the Magistrates and Subjects may by this means reap much profit and help. The Magistrate may be satisfied by taking Corn of the Inhabitants instead of tribute. The Subjects may by the benefit of this Medium satisfie the Magistrate, and there will not need the selling his Cattle, or Sheep in the Fold, or to borrow Money upon use, and to give his Wife and Children for pledges. For there is requisite no other labour than that the Magistrate appoint a place to boil his Ale, in which the Corn may be malted, boiled and thickned into Juices. As for Wood, that he has himself and needs not lay out a farthing upon that. So now, by this means may a Country be brought to that degree of happiness as never to want Money, Corn, or any other necessary things. For where the Juices can be but brought to the Sea-towns many thousand Barrels full may be sold to those Magistrates and Merchants which send their Ships into the East and West-Indies; in which Countries may be made good Ale at any time of the Year, even in the midst of Summer, or in the Dog-daies themselves, if you have but Hops and Water at hand; the which is far better and more profitable.
