52 They make their vitrioll at Depthford as they there told us thus

They make beds of whole copperis stones (which they have cheifly from Chitwick & the Isle of Wight) of an arbitrary length & bredth['bred' altered from 'dep'] & of about 2 foot in depth these beds are made somewhat shelving that the raine [ '& Sunn' deleted] falling upon the stones & assisted by the heat of the Sun to dissolve the copperis lurkeing in them may run into certain tubs plac'd at the lower extremitys of them & to this purpose also there is under each of these beds [ 'there is' deleted] a floore <made> of such beaten clay made that the water will not penetrate it All these particular tubs doe by pipes with stoptells fitted to them to be taken out onely when need requires empty themselves into one great tub whence by a pipe with a stoppell fitted to it the vitriolate liquor is when the workmen please convey'd into a very large Cisterne from which it is as need requires pump'd up with double pumps under which are placed wooden troughs to convey the pumped liquor into great square boylers (as they call them) which are made of sheet lead (because that either Iron brasse or copper vessells would be corroded by the liquor) where it is boyl'd for 10 15 or 20 days or more dureing which time the workmen cast in by degrees as much old hamer'd (but not cast) Iron as they liquor will conveniently dissolve, & then opening certan pipes which are at other times kept stopt in the boylers the liquor is thence convay'd into other great vessells which they call Coolers where being suffered to rest for 8 10 or 14 days it shootes into vitrioll, NB: 1 That in their boyleing [BP 26, fol. 99 (original pagination p. 19)] furnaces [ 'that' deleted] they use sea=coales 2ly: That one bed will last 7 or 8 yeares or more but yet they strow some quantity of new stones on it almost every yeare 3ly: <That>[replacing 'At', Boyle hand] The bothom of their great Cisterne is made onely of comon planks [ 'as they call it' deleted] well <arm'd>[replacing 'calk'd'] with <comon>[insertion in margin ] pitch or as[altered from 'th'] they call it well calik'd as shipps are wont to be onely instead of Iron Nailes['N' altered from 'p'] they use wooden pegs or trunnells. 4ly That if the liquor boyle but a litle too long they say it is quite spoyl'd & will yeild onely a greasy substance (as they <speake>[replacing 'call it'] but never make good vitrioll. 5ly That they say they pay for their stone brought to their beds [ 'for' deleted] 20 <s a tunn> & sell their vitrioll for ten pounds a tunn each tunn consisting of 20 hundred pounds to the tunn,

53 The Standard maker when he lays leafe silver upon Standards first covers them severall times with whiteing & then with Size but if he be to lay it on skins he uses Size alone mixing equall quantitys of strained size & faire water & spreding this mixture with his hands upon the skins till they be fully glutted with it & will drinke up noe more then he lays on his leafe silver & pollishes it with a smooth stone & on this Silver he lays his gilding vernish the first time & letts['s' altered from 'ing'] it [ 'wet' deleted] dry well on (either in the Sunn or shade according to the nature of the vernish) Of which laying on more the 2d time & letting it dry the skin is gilt On[altered from 'And] this gilt skin you may lay for green [ 'you may lay' deleted] verdegrease finely ground with comon white vernish, but for red you must use <a litle>[insertion in margin ] Lake finely ground with <a good Quantity of> some drying oyle which you may make by boyleing for about an houre halfe a pound of umber in about a quart of good old Linseed oyle,

54 Take of fritta ten pound & as much putty made [ 'of' deleted] by calcination of six parts of Tin and foure parts of lead & let these three Ingredients stand in fusion their due time to make Amell white

55 Take fritta six pound of the aforemention'd Putty foure pound Zaffora one pound let these stand in fusion their due time to make <blue> Amell [ 'red' deleted]

56 To make red Amell you must use Magnesia & scales of Iron N.B. Fritta is made of equall parts of pure white sand & Borallio reverberated till they incorporate together

57 Colour your [ 'F' deleted] Glasse red with <a very litle> Manganese green with Copper calcin'd per se.

58 Take Minium 4 parts & Copper calcind one part melt them together & make thereof a coloured past try likewise with Fritta 4 parts & Manganese one part or els with Manganese 1 part & Minium 4 parts keeping them their due time in fusion for one of those two ways will succeed

59 Upon peices of grossly tincted Fritta lay fine [ 'beat' deleted] leafe gold & presse it on upon the Dice being first a litle moisten'd to make it stick then strow on them as much finely powder'd Crystall glasse as is convenient that until the fusion of the['se' at end of word deleted] glasse in a moderate but competent heat the Gold may be uniformely cased.

60 Take Flints heat them red hot & quench them in faire water & doe this soe often till you can reduce them to an impalpable powder then with as litle fixt salt & flux[altered from 'flux'd'] as may be run them with convenient colours then powder the vitrifyd Masse & free it as much as you can with distill'd vinager['a' altered from 'g'] or otherwise from the salt or flux or both & vitrify it once more to harden it

61 Melt a pound of Rosin & to it add a quantity of a beane or nutmeg of yellow wax then by nimble stirring incorporate with it as much powder of beaten bricks as will suffice to bring it to a consistence fit for a cement for Glasse fountaines.
