ed with Pitch or Resin, äs will make the Thickneß of the intended Statue,

vvliich I form in the Wax with all the Exactneßpostible.

Here Note, that the Particles of Mctal mentioncd to he fet into the Core,to keep it at a distance from the Mould, must be so fet as to fall in with theSurface of the Wax cxactly : and that the reafon of mixing Pitch or Rosin withthe Wax is, because that when !t is Burnt out, it makesa great fmoak, andthat Smoak adhering to the Mould, occasions the Mctal to run more freely; as Ihave experienced it. Next I put all over upon the Surface of this Statue ofWax, little pieces of Wax which 1 call the little Cbanneh cccccc, (allwhich mustbe contrived so asto enterinto the Great Cbanneh ddd.j This doneI cover the Core and Wax all over with the fame sort of Clay,that will endurcthe Fire without Cracking j and so I have my Concave Stante or Mould. made.Upon this I lay the great Cbanneh marked dddd, both upright and transverse,Formcd likewife in Wax, and placcd according to Judgment, io as bell toreeeive the Ends of the little Cbanneh ccccc, for the more caite distributionof the Mctal. These Great Cbanneh must: all meet at the top of the Statue,so as tocome out by one Hole, as at E, where the Aletal is tobe poured in;

It is also necestary to have a Cbanncl or two to let out the Air as the Mctalenters, as thole marked //, and there must be a Hole or two lest at theFoot, as g g, where the great Cbanneh and H axen Statue joyn ; and where-at when the A-f nid is Burnt, the Wax as well of the Statue as of the Cbanelsmay run out. The great Cbanneh being thus piaced, the Mould must be a-gain laid over with the famc fort of Clay ; (I ufe constantly to bind aboutthe Mould with Iron Wire and theil lay on more Clay ) and when this Mouldis well drie, then I Hcat it Red-hot; as I did before the Core, so now bothtogether.

I Burn the Core irrst, that there may not need so strong a Fire to Burn theMould as will melt the fmall bits of Mctal : But for fmall manageable Sta-tues of not above a Foot or two High, they may be both Burnt together, andthere is no need of the Holes gg, but the Mould may be lnverted, and theWax run out by the Cbanneh ff, and E.

The Mould being thus Burnt, I stop with the fime Clay the two Holesg g, and then I bury it in a Pit, and proceed as is ulual in Casting of Bellt,and the like : but care must be taken that the Mctal be very well in Fusion.

If it be a fmall Statue not above a Foot or two High, whofe Adould may beManstged in ones Hands, then I make me a Concave Statue of Wax, of thethicknefs I delire, and then place upon it all thofe great and lester Cbanneh,as afore: Which done I put it all together, into a Liquid Substance made ofPlaister and Tile or Brick-dust temperedwith Water.

If the Statue be intended very Thin, then I take Coppcr, and when it iswell in Fusion I mix with it a good quantity of Zsnc, without obferving any’certain Proportion of Weight; the more ZJnc the better the Mctal Runs. Ihave sometimes for fmall and thin Statues put in above a third part of XJnc. 1have found by experience, that this Mineral makes the Mctal run most freely,and gives it a fair Golden Colour.
