Notes for MINT00159 (Mint 19/1/228-9)

<252r>

An ingot of Gold is assayed by refining a small part of it with two water after the same manner {illeg}that Refiners refine Gold in great quantities, & takin observing the increase or decrease or increase of its weight by the operation. T I

If there by no increase or decrease of weight the go Ingot is reported 24 carats fine, & there it being of the same fineness wth the piece refined by the Assay. And this is fine gold in the sense of the law of England & of all nations who practise this way of Assaying. But if there be a decrease of weight, the decrease is observed & the Ingot is reported so much coarser then fine gold as the decrease of weight amounts unto.

The Refiner makes fine gold by refining it after the same manner by the Refiners art is a great quantity as the Assayer refines it in a small quantity. The gold must be mixed with silver in the same proportion in both cases & blown of the Tested wth the same degree of hea proportion of Lead & in the same degree of heat in both cases & laminated to the same thinness in both cases & watered twice & but twice with waters of the same strength in the same proportion & heat & length of operation th{illeg}at ye waters may work alike in both cases, & bring the gold to the same degree of finenes in both cases, th th without roasting it

But it ye {illeg} operations be not alike the gold may become finer or not soless fine by the Refiners art then by the Assayers, that is finer or coarserless fine then 24 carats.

And because Refiners seldome {illeg} re at the pains & c{illeg}harges of making gold so fine as it is made by the Assay, & therefore the Iury who makes the standard Trial assays the Refiners fine gold & if it be not 24 carats fine they roast it to bring it to a due degree of fineness. And when the trial piece is made they {illeg}assay it several times to see if it be standard. {illeg}

It's possible for a Refiner to make gold finer then by the Assay. {illeg} & a Chymist by Antimony makes may make it still finer And therefore ye Iury should take care that ye fine gold be not too fine. And that it be neither too fine nor too course they should assay it several times.

Vpon{illeg} In the stature of 112 Hen 6. C. 12, the Assa Kigngs Assayer is called an indifferent person indifferent between the Master of the Mint & the Merchant, & it is there ordeined that he attend weekly to be present when Bullion of silver is brought into the Mint that he may rightfully set the value upon the same according to law in case of variance between the Master & the merchant. TAnd therefore I humbly pray that her Maty may be put in mind of orde{illeg} ordeining an Assaymaster before her departure to Windsor, And since Mr {illeg} Charles Brattel is approved by both parties between whom {illeg} the Assaymaster is to be as a fit Arbitrator, between them & hath carried on the business of the Mint between them for some months without & been eavenly for some months without any d{illeg} variance arising between thesaid two partiesmm, & hath been freely freely entrusted from time to time by the Merchants with great quantities of Bullion without any miscarriage, & or complaint, {illeg} & if any variance or miscariage should happe{illeg}n {illeg} it would tend to the discouragement of the coinage [& the variance must be decided by an Assaymaster to be appointed by her Maty before the Mint coinage can proceed] I humbly recommend Mr {illeg} the said Mr C. Brattel as a person well qualified for the said place of Assayerfor the said Office, in point of skill, {illeg}diligence, {illeg}credit, & equity between the said parties probity.
