refined and separated lesser metals and minerals, to be exported and traded outside of the country as circumstances allow.

In the event, however, that the

Establishment of three liquation worksoriginal: Saigerwerck; facilities used for the 'liquation' process to separate silver from copper. in different locations.

landowners and mine operators do not have the opportunity or desire to extract the gold and silver from the aforementioned lesser metals through liquationoriginal: Saigerung; a metallurgical process where lead is added to silver-bearing copper; when heated, the lead-silver alloy melts and "sweats" out of the copper. and other means, then we hereby graciously grant that, for the benefit of the general mining industry in this Crown of Bohemiaoriginal: Behem, we shall cause three smelting houses—with all necessary equipment—to be established and erected in the three most convenient locations. This shall be done so that all those—whether they be landowners or mine operators—who bring in black copperoriginal: Schwartzkupffer; an unrefined intermediate copper product. containing silver to these locations shall be paid twelve white groschenoriginal: weiſz groſchen; a silver coin of the period. for every lotoriginal: Loth; a weight of approximately 14–17 grams. of fine silver. Likewise, for every hundredweightoriginal: Centner; roughly 50-60 kilograms of refined copperoriginal: Garkupffer; literally "fully cooked" or finished copper. produced from the black copper according to the assayoriginal: Prob; a chemical test to determine metal content., seven shocks of Meissen groschenoriginal: Schock Meißniſch; a 'shock' is a counting unit of sixty coins. shall be paid. However, in accordance with custom, for every hundredweight of refined copper found in the black copper by assay, there shall be a deduction for waste, and for what remains within it, two lots of silver shall be deducted, along with our standing due of the titheoriginal: Zehenden; the 10% royal royalty..

As for what the land-

owners and mine operators deliver in the form of silver-bearing lead, the lot of fine silver shall likewise be paid at twelve white groschen. However, nothing shall be deducted for waste; only our due tithe shall be taken. The lead shall also be compensated separately according to its current market value.
