POT and PEARL ASHES.
TO THE PUBLIC. HAVING attended carefully to the reluit ot several comparative experi ments, which were made to ascertain the nature and meri s of Samuel Hopkins pro cess for manufacturing pearl allies or calci i,id alkaline salts, we are of opinion, that by his method wood aires may he made tc yield a quantity of pearl allies of a very fine- white colour, equal in weight an.: ftreneth to the black or uncalcmed alka line salts which are obtained by the ordi nary method of leaching and boiling dewi: the 1 lack leys, so that the manufadtuiei who adopts this method, will probably .rain all the weight which is 101 l by the or dinary proc.fs of calcining, and m;:y efleCi tie calcination in a much eaf.er manner. We also examined a furnace erected accor tjjng to the direaionsot Samuel Hopkins, and were present during part of a process which wa,~ co< du<fted in it and believe ii to be so happily conllru&ed as to effect tlu calrina ion'of wood alhes, and evaporate the leys without more fuel than is used te boil down the leys only by the commoi method. * David liittenhouje. + Benjamin liuju, j James Hucbinfan- Benjamin Say. II Ca/pcr IViJhr,jun. John Pcnington. June 17, J"93* In addition to the foregoing certificate I conceive it proper 10 inform the public in what refpe. my process differs from thi uftial method, and to offer f..me direftiom to such as may iucline to adopt it lit. hi; jv i.cess confiiU in cacming ccuimr.il Lotile or field allies » a farnaci of a pecuiiar conduction lo contrived thai the fame fire that boils down the leys cal ernes the alV.es ; hence it appears there 1: nor a greatei enfumption of wood in thu new process than is necessary in the former in biaining black salts, ano the a'hes fron the wooc' so 'bo ing saved, which was be f,, rt mu t;i ' ~ occasioned hy the ftronc dratight r> ceffaty to keep the kettle: baling- , , , 2d I is 'ee.>mmended to such as m?j adept this method, to pav particulai at tent ion to the firll part of the pru.Ce s, viz calcining the alhi s properly; for this being carefully performed, the fubfrquent it<*p become easy and i fs liable to fail. 3d. The alhes fnould be spread over th< hearth of the turnace not more than on. inch and anlialf thick, direst a lively blaz. on them until they, beconv red hot, keep ing them frequently stirred, and the dam pers well cloieii. 4th In order that the workman ma) know when his-afhea are fufficiently burr' w ,til, he becomes enough perfect hi th< bufmefs, from other circumtlances, a Imal parcel may be taken out and put 111 aglaf: with water, if the alhes fettle quickly aftei stirring them, and the leys appear colour, less, they ar<? fit for drawing into the all: pit ; if ihey are calcined longer the quan tity may he durtiHilhed. eth. After the fires begin to burn, every part of the furnace fhouid be kept as clole as possible.the door of the ash pit and hearth, and that for introducing the ashes cn the he arth, Ihould be made to (hut complete, for I have reaf 11 to believe a great draught of air carries off much of the salts. 6th. Great cure Ihould be taken not tc put more alhes into the furnace than I have dirtfted above ; it has been found b" experiments that when much more have been put in, the faits are not so white not the quantity so great. I believe it was for want of attention to this circumstance and allowing too great a draught of air, that some who attempted my process have not been so fuccefsful as was expeft^a. 7th. The alhes are drawn from the ail) pit the next day ; after calcining and put into leach tubs, the leys drawn from then alter fettling ave boiled down, the fait: kept well llirred in finifniiig off, until the) become perfe&iy white. * Prcfldcnt of the American Philofoph'ica Society. f t'rofeffor of the 'nftitution and Clinica Medicine in the Unjvcrfity as Pennsylvania, for erly Profeffor of hemiftry. 4 Profeffor of chemistry in th« University. jl Adjunct ProfefTor of natomy, Surveyoi gcc. in the University, formerly Proleffor of Chy. miitry in the College he other two whose names are without re ferences, are phyiicians ol this city. Bth. If the salts fliculj not become the colour as is described in the fi:ft instance, through an imperfect calcination, '.hey may be dissolved, fettlid, and boiled down again. The advantage arising from this pro cess may beconipnied under the following heads. ill. By calcining the allies before the leys are drawn from tliem, we obtain as threat a quantity at lead ot pearl alhes, as of common black falts;pearl ashes general ly fell when at market ?.t 501 per to-i : the highest price for black salts is 251. per 'on, and if converted ir.to pearl alhes, it requires as much more labour and fuel r.s in the fir ft instance, and a loss from 25 to 30 per cent. The foregoing observations are intend ed for such as are or m;iy be engaged in the manufadturing of pot and pearl ashes; they will cafily underfland the terms 1 have employed ; for the information of others it may not be amils to explain, what 1* meant by bUck salts, pot alhes and pearl ashes. 2d. Black salts are made by boiling down the leys from common wood ashes, until they ore perfectly dry. 3d. Pot alhes are made by melting the black salts in a very itrong fire, and lading it out into coolers. 4th. Pearl alhes are made by putting the bl ck salts into a furnace prepared for I hat purpose, and throwing a llrong b.aze on them ; this operati on is cal ed fcorch i.'g; they are then dissolved in water, fet tled and boiled down 'again, returned back into the furnace and calcined until they are fufficiently white: Pot ashes made from calcined ashes are allowed to be much superior to those made in the cominoti mode I expect the names and characters oi molt of my fellow c.tizens that have sign ed the foregoing certificate are well known; they are allowed tobe well acquainted with chemillry. A furnace was ere£led for one of them, who kindly undertook to make the neceflary comparative experi ments, according to my directions ; the result of which is-already let forth. SAMUEL HOPKINS. 6th Mo. 22d, 1793. I do certify, that I have crefkd a small -furnace, in the suburbs of this city, op the patent method, for the purpose of mi.nu- L£turir,g pot and pearl ashes, which T find to consume on an average no more than one cord of wood per week ; two 1 ands will calcine 20 bushels of ashes per'day, and bale down the leys therefrom hi the lame time, which if well calcined will pro duce pearl ash the firft boiling. Ihe are not so apt to boil over as those in the common method. —The txpenfe of the said furnace, excluflve of the boilers, did not exceed ten pounds currency. JOHN REELS' Philadelphia, June 20, 1793- CHARLESTON, (S. C.) Ma 7 17. A gentleman on the South Fork 6' Sa luda river, in a letter of the 23d uit. fends his correspondent in this city tne following defcripiion of an extraordinary animal which has been lately discovered on the Bald Mountain, and on other mountains iu the Western Territory : — This animal is between twelve and fifteen feet high, and in shape refem'oling a lui man being, exoept the head, which is in equal proportion to its body, and draws in iomewhat like a tarapin ; its feet is like those of a negro, about two feet long, and hairy, which is of a dark dun colour ; its eyes are exceedingly large, and open and (hut up and down its face ; the hair of its head is about fix inches long, (lands itraight like' a ueigroe's ; its nofc is like that of ti human species, only large; and inclined to what is called lloman. These animjls are bold, and have lately attempted to kill several persons—in which attempts some of them have been (hot. Their principal resort is on the Bald Mountain, where they lie in w it for tra vellers—but foine have been seen in this part of the country The inhabitants of this plac call it Yahoo : the Indians, how ever, give it the name of Chickly-Cudly.
