CHAP. CVIII.
MAkc a Lee of Bari Ilia, and of Limc$ reafonable ftrong; and in this Lee, boil boil at a gentle fire frefh Broom Flowers, that the Lee may draw to it all the tin- dure of the Flowers,which you fhall know by taking the Flowers one and feeing them whicejSt the colour well taken our, and the Lee will be yellow like good Trelian wine : then take out thefe Flowers, an J puc this Lee in earthen difhes ( glafed ) to the fire, chat the Lee may boil, and put into it, fo much Roch-Alum, that with the fire, all the Alum may be difGalvcd ; then make a fire, and empty this Lee into a vef¬fel of clean water, and ic will give a Yel-low colour at the bottom .• let them fettle, and decant off all the water, and again put upon them other frefh water, and decant it otf 5 let the tindurc firft fink to the bottom, and do this fo long, till you have taken out all the faits of the Lee and Alum from the tmdure ; obferving that by how much the more you wafh this tindure from the fait of the Lee and Alum , by fo much more will the tin¬dure of the colour be fairer, and more beautiful, wafhing it always with water to carry away the falc of the Lee and Alum, and at each time before you decant the water, let the Yellow t indure fettle to the bottom. Repeat this process, until you perceive the water run out sweet and with¬out saltness as 'twas first put in, and then at the bottom will remain a beautiful and fair Lake: which spread,when wet,upon pieces of white cloath, and dry it upon new ba¬
ked Bricks in the shade, and you shall have a beautiful Lake of a Yellow co¬
lour, for Painters, and also for glass.

The/The manner how to colour within,Balls of glass, or other Vessels of White glass,with all sorts of colours,which will imitate natural stones.
CHAP . CXIV.
T Ake a Ball, or other sort of glass that is white & fair, & Isinglass which must be infused two days in common water, then put this infusion into a white pan with fair water,and boil it till all be well tempe- red,observing that the Isinglass will be very tender with much water, then take it from the fire, and when it is warm, put it into a Ball of glass, & turn the glass round,that the Isinglass may fasten and wet every where the glass within, this being done let the moisture drain and run out, then have in order these colours powdered,to wit Red¬lead; and casting it into the glass it will make the said colour stick (which will run in waves) cast it into many places through a tube, then throw in blew smalts making it ftick in waves, within the Bal!. Then do the fame with Verdigreas, then with Orpi- ment, next with Lake, all well ground, always calling the colours in many places in waves, which by means of the Ilinglafs which hath moillncd the glafs within, thole powders will every where ftick to the glafs ; and fo fhall you do with all colours. Then take Geflo well powdered, and put enough thereof into the Ball, and fuddainly turn ic about, that it may ftick every where to the glafs within. Do this work nimbly whilft the moifture of the Ilinglafs glafs lafteth,that the powder may ftick well, then empty by the hole of the glafs the Gclfo which is within the Ball, which fhall then appear of divers colours with a moll fair appearance like the na¬tural Toies of hard ftoncs, and at laft thefe colours (whenthe Ilinglafs is well dryed) flick fo that afterwards they will not fall off, anti alwayes their colour is moft fair without. Fit to thefe Balls a foot of wood, or of other fluff painted, and they arc held for beauty before Cabinets, and for Mer¬chants counting houfes very fair.

*T"Akc fragments of Lapis Lazuli, found * plentiful at Venice at a low price , let thefe fragments be well coloured with a fair Skie colour, lay aiidc thofe that arc not coloured,calcine them well in aChry- fiblc, and fo heated , caft them into cold water,repeat this twice, then grind them upon aPorphyric,toan impalpable powder as fine as wheaten flour fitted.
Take then three ounces of the Rofin of the Pine, Black Pitch, Maftick, new Wax, Turpentinc,of each three ounces, Linfccd Oyl, Frankinctnfe,of each an ounce, dif¬folvc them in a new earthen Pipkin at a gentle heat, ftir and incorporate them with a Spatula, then caft them into cold water, that they may'clcavc in a lump tor your need.
Take tor every pound of Lapis Lazuli ground as before, ten ounces of the afore¬said paft of sums, which diflolve in a Pipkin
170 Theftventb Book.
Pipkin at a gentle fire, and when it is well diffolved, caft in by little and little, the faid powder of Lapis Lazuli* and incorporate it with the gum with a Spatula, I caft all the materials thus hot being incorporated fuddcnly into cold water, and bathing my hands with Linfced Oyl, made a round paftill hereof long and proportionally thick. Of thele paftils you may make one or more according to the quantities of the materials, keep thefe paftils fifteen days in a great vcftel full cf cold water, changing the water every two days, then fhall you boil in a Kettle common clean water, the paftils in clean and well glafed earthen pans, and caft upon them warm water, and fo leave them till the water is cold, the faid water being emptied out, caft upon them new warm water, and when it is cold empty it out, putting in again warm water, and when it is cold, empty it out,putting in again warm water, repeat this fo many times till the paftils be diffolved by the warmth of the water, then put in new warm water, and you fhall fee the water will be coloured of a Sky colour, decant the water into a pan well glafed and clean- fed. This calling on of warm water upon the the pastils, must be repeated till it be no more coloured, but observe that the water be not over hot, but luke warm onely, for too much heat makes the ultramarine grow black. All these coloured waters strained into pans, have in them the un- ctuosity of the gums, therefore they must be lest to settle 24 hours, that all the co¬lour may sink to the bottom, then the wa¬ter with it's unctuosity must be leasurely decanted off, put upon the pastils clear wa¬ter, and then strain the cold water thorow a fine strainer, stirring the colour that it also may pass the strainer,and by this means a great part of the foulness and unctuosity will remain in the strainer,wash the strainer always with fair water. And with new water pass the ultramarine thrice thorow the serce, washed every time, and then usu¬ally all it's filthiness will remain in the strainer. Put the ultramarine into clean pans, decant the water softly off, which dry of it's self, and you shall have a most beauti¬ful ultramarine, as I have often made it at Antwerp. The quantity from a pound of Lapis Lazuli shall be more or less accord¬
ing as the stone is of a fuller and fairer co¬lour. Then grind it to an impalpable pow-der on a Porphyric ( as is abovcfaid ) and ’twill arife moft beautiful. If you take common Blew fmalts ground on a Por- phyric to an impalpabje powder , and incorporate it with the gumtn paftils with the forefaid quantities , keeping them- in- digeft'on in cold water 15 days with Lapis Lazuli, and work thorowout as in Lapis Lazuli, you fhall have a very fair and light¬ly Blew Bice, which will fecm to be an Ul¬tramarine. Thefe Blews not onely ferve for Painters, but to colour glafs excel¬lently.

Then take the Flox Alumed as before, which muft firft ftand in a pan of cold water for half an hour, and when the wa¬ter is well coloured, prefs well the water from the Flox, put it into a pipkin, and ftir ic abouc very often, with a little ftick, that the Flox may be well tinged , let it ftand half an hour over the fire that it may boil gently5 then take the pipkin from the fire, and take out the Flox, mixing it with a clean ftick, put it into pans full of cold wa¬ter, and in half an hour let all the water drain off, and put more cold water, let that drain, and prefs it well, and fet it to dry in a place where no dull falls, fpread it a- broad The seventh Book.
broad that it may not become musty, and heat again. Take heed that the fire be al¬ways very gentle, for with two strong a. fire the colour becomes Black. Then shall you make a Lee in this manner, to wit,
Take ashes of Vine branches, or of Willows, or of other soft wood, put them upon doubled Canvas, and pour gently on them cold water, let the water run into a pan, pour twice this strained liquour upon the ashes, and let the Lee settle 24 hours, that the ashes may sink to the bottom, and when 'tis pure and clear, decant it off into other pans,putting by the terrestriety which is not good.
Put the said coloured Flox, into a clean and cold pipkin, with the Lee,boil them at a most gentle fire, for so the Lee will be tinged with a Red colour, and will draw the tincture from the Flox, and at first take a little Flox and press it well, and if the
colour bedischarged,take the pipkin from the fire, and this is a sign that the Lee hath drawn the tin&urc of the Cochineel from the Flox.
Hang an Hyprocras bag of Linnen, over a great and capacious pan, strain thorow this bag all the tincture from the pipkin, and
i"j6 The feventh Book.
and let the Flox alfo go into the bag, when the Lee is drayned, prefs thci>ag where the Flox are, that you may have all the tindure.- Then wafh the bag from the hairs of the Flox, turning them infide out¬wards, that they may come forth pure and clean.
Then take 12 ounces of Roch-alum powdered, put it into a great glafs of cold water, let them ftand till all "the Alum is diffolved, then fitly place the faid bag well waflied from the hairs of the Flox betwixt two flicks in the air. The bag mull be large at the mouth, and narrow at the bot¬tom, fowed in the manner of a round pyra¬mid , and under the bag fet a clean pan, then call all the Alum water into the pan where the tindure of Cochincel is, and you fhall fee the Alum water fuddcnly fc- parate the tindure from theCochineellikc asaCoiguIum doth. Then with a clean difti call into the bag all the faid tindure and Lee, which will run clear out of the bag, but thetindure will Hick to the bag. ATd when all the water is well neer out, if happily any ftrain chrough fomewhat co¬loured, pour ic again into the bag, and then this fecond time 'twill leave all the tin-durc dure in the bag., and the Lee will then run white and difeharged of tindure. Then take clean fticks, and therewith mix the tindure which (licks on the bag in grofs pieces, aid have in readinefs new baked bricks,whereon fpread little pieces of lin¬nen, and on the linnen fmall pieces of Lake which you fhall take ouc of the bag, let them dry well, fpread them not too thick that they may foon dry, for when the Lake (lands long wet it grows mufty and makes a foul colour. Wherefore you may, when the brick hath fucked out much moifture take another new brick, and fo you lh all foon dry it. When ’tis dry take it from tfie linnen,and this is a good Lake for painters, which I have oftentimes made at Pifa. Ob¬ferve,that if the colour be too deep, you muft give it more Rock-alum , but if too light lefs Roch-alum , for fo the colours arc made according to you guft and will.
Lake of Brasil and Madder Very fair.
CHAP . CXVIII.
IF you would make a Lake of these mate¬rials each of them by themselves, you shall do in every thing as is before said of Cochineel, colouring the water with one of these materials, but you shall not use so much Alum by an ounce as you did in
Cochineel, for Cochineel hath it's tincture deeper than Brasil, & Madder have. Wher-fore you shall give them their proportion, which you shall find by practice. And also to one pound of Flox you shall use more Brasil or Madder, for they have not so great a tincture weight to weight as Co- chineel hath. And in this manner you shall have a very fair Lake for Painters, and with less charge than that from Co- chineel, and that from Madder in particu¬lar will arise most fair and very sightly.

CHAP. CXIX.
IN this way invented by me at Pifa, you meet not with Flox nor Magifterie, nor Lee, nor dying the Wooll, nor fo many things as go the former, which indeed is a very laborious way, though moft true. But this way is moft calic,ind worketh the fame effed, and tis this which followeth.
In a pottle of Aquavit* of the firft run¬ning, put one pound of Roch Alum well powdered,when it is all difTolvcd , put in an ounce of Cochineel powdered and filled in every thing as before , put all this in a glafs body with a long neck, and fhake it well, and the Apia vit* will be wonder¬fully coloured, let them ftand four days, then empty this ftuff into a clean earthen glafed pan, then diftolve four ounces of Roch-aluin in common water, caft this into the pan of Apia vit* coloured with
N * Cochi- Cochineel, and put this into the Hyppocras bag, and fo proceed throughout as in the 117 Chap. This is a moft noble Lake from Cochineel,made with fmall pains, and in much greater quantity. All this was trycd at Pifa.

'J’Ake Manganefe ground to an impal¬pable powdcr,mix it with as much more refined Salt-peter, fet it to the fire in an earthen pan to reverberate and calcine 24 hours, then take and wafh it with common warm water from it’s faltnefs, the fait be-ing feparated, dry it, and it will be of a Red colour,hcicto add it’s weight of fal Armoniack , and grind them together on a Porphyrie,wet them with diftill’d vinegar, ler them dry, then put them in a Retort which hath a large body, and a long neck, give them a fubliming fire in fand for 12 hours, then break the glafs, and take all that is fublim'd to the neck, and body of the Retort, & mix it with the bottom & re¬maining residence, weigh them and add as much sal Armoniack as shall be wanting in this first sublimation, grind them all toge¬ther on a Porphyrie, imbibing them with
distilled Vinegar, then sublime them in a retort as before, and this sublimation is to be repeated after the same manner so long till the Manganese remain all at the bottom fusible.
This is the medicine that colours Cry¬stal and past into a Red Diaphanous co¬lour, and into a Rubie colour, there are used of this medicine 20 ounces, to one of Crystall or glass,but more or less may be used thereof according as the colour re¬quires. The Manganese must be of the best from Piemont, to colour glass of a fair, and very sightly colour.

T? make then the Fitriolum Peneris a- bovefaid, take one or more very capa¬cious Glafs bodies,according to the quanti¬ty of the Copper calcin’d, and prepared, to wit, to a pound of Copper take a body which will hold fix pints of watcr3puc this common clean water into the body with calcin’d Copper into a fand furnace, give them a temperate fire for four hours, until of the fix pints of water, there be evapo¬rated about two, which is feen by the eye 5 let the furnace cool, and gently de¬cant off the water into earthen pans glafed, and the Copper which remains at the bot¬tom puc into pans in a furnace to evapo¬rate all the moifture, and the water which is decanted into the pans will be coloured with a full and wonderous fair blew , let them ftand thus in the pans two days to fettle, and part of the Copper will fink to the bottome in a Red fubftance, then Filtre the faid warer with ufual lingucts into glafs veflcls,and evaporate from the faid Copper all the moifture, and with fix ounces of Sulphur calcined, powder and. ferce it to a black powder, as in Chap.
131. and then as in the beginning of this pour in water and extra# the Blew co¬lour. Confidcr that in this work many pots will be broken,wherefore as often as the pots are broken or cleft take a new one, left they break in the furnace, and all your labour be loft; when the humidity is eva¬porated put the fame quantity of Sulphur powdered and fe-rced, and do as before.
The reafon why the Copper is to be taken out whil’ft it is hot, is,becaufe then ic is bet¬ter feparated from the pots,8c it is impofli- blc to feparate ic, if you fuffer it to be cold,although you break the pots. Repeat this procefs not onely four but five or fix times in every thing as before, Then the Copper will remain as a foft earth, and the better and moft noble tindure of it will be in the-Filtred waters, all which mixed together must be Filtred with the usual lin- quets, ana the setlings and dregs may be cast away as unprofitable, then you shall have a most limpid water, and coloured with a most marvellous blew colour.
The way to extract Vitriol from the faid colour d waters.
CHAP. CXXXIII.
sEt then a great glass body that will hold three Flasques of liquour in ashes or sand in the furnace, and with a tempe¬rate fire evaporate the said colour'd wa¬ters, and neer to the furnace keep other glass bodies full of these colour'd waters, that they may be warm, and now and then fill the great body, which is in the sand with glass ladles, do this that the co¬lour'd waters may be put in warm, for being put in cold they will make the great glass body break; evaporate the colour'd liquour from ten Flasques to two and a
half or three, then these waters will be deep and full of tincture, which put int earthen earthen glafed pans in a told and moift place forani-ht, an you fhall finde the Vitriol fhot into point ke CryihUs,which will appear like true Oriental! Emeralds, decant oft all the water that 1. in the pans, dry the Vitriol, and let it not ftick to them, then evaporate half this water, which will yield you new Vitriol as be¬fore, Repeat this till you have gotten all the Vitriol. Put this Vitriol in a Retort well luted with a ftrong lute, fee you put no more than one pound of Vitriol in a RctortjWhich muft not be very large, and have a large and capacious receiver; make for 4 hours together a moft temperate fire, for if it be too ftrong the moift and windy Spirits wch firft arife trom this Vitriol,are fo powerful, and arife wich fo great force, that no receiver is able to hold them ; let the joynts alfo be very well luted. Ac laft make a ftrong fire when the dry Spirits be¬gin to rife in a white form , continue the fire till the Receiver begins to wax clear, and to be quite cold, then make no more fire, and in twenty four hours let the joynts be unlutcd,and the liquor which is in the Receiver muft be kept in glafs very well fcaled. This is the true lively Azure,with O 4 which/which marvellous things are done, as you may well perceive by it’s fmell, which is as powerful and lharp as any this day known in nature.Many things might be faid,which are paffid over as being not pertinent to the Art of glafs, which happily you may judge upon better occafion; the feces then which remain at the bottom of the Retort will be black, which left fome days in the air of thcmfelvcs will take a pale blew, powder and mix this with Zaffer* and put it to Cryftall metall as before, and with the faid quantity will be made a marvellous Sea-green. Wherefore 1 have here fet down the way to make this powder with much clearnefs, prefuppoling that I have not pub- lilTied an ordinary way to make it, but a true treafurc of nature, and that to the con¬tent of noble and curious Spirits. .
