Sor ** Salifoury Angola Moleskin,” iz 
imitation of Velvet. : 
This fubftance is manufactured on'two 
chains or warps, the upper one is 
invariably woollen-yarn, but the umder 
chain is ef cotton, linen, filk, mohair, er 
worlted. Thefe chains are upon feparate 
beams, the number of threads in the up. 
per chain is two-fifths of the whole num- 
ber in both chains; wires being intre- 
duced when the upper chain is clear upon 
the farface of the ground, and kept con- 
fined by three threads of weft till cut out 
by an infrument,.thus the face or pile is 
formed ; the weft is of cotton; linen, fik, 
mohair, worfted, or woollen-yara, 
‘MR. JOSEPH HATELY’S (CRADELY, 
WORCESTER) Yor fome Reducing Fluxes 
Sor the Purification of Mineral and Ms- 
tallic Bodies, Ge. - 
The purification of thefe fubftances 
1s eftetted by the addition and appli- 
cation of certain fluxes, or any mixture 
of them together with or without abfor- 
bent fubftances of lime, gypfum, chalk, 
and whiting mixed therewith, confifting 
of the refidue adhering to falt-pans and 
boilers, in which the fea-water brine and 
falt-rock are boiled. 
In fome cafes the patentee ufes falt- 
water, &c. to refine copper, lead, tin, 
Zinc, bilmuth, and antimony. ‘Tine ores 
are firft cleaned and pulverized for melting 
in the ufual manner.. The fluxes may be 
ufed either in a crude or prepared ftate : 
the latter is upon the whole preferable, 
which is done by melting the falts, and 
mixing them with two parts of the recited 
abforbent fubftances feparately or together 
in a calcined ftate. Of this compofition, 
two pounds are ufed to every hundred 
weight of crude oie before exprefled ; and 
double that quantity of the unprepared to 
the fame quantity of ore aforcfaid, more 
or Iefs as the ores or metals may require 
for rendering them ultimately pure. 
To refine iron ores, or iron mine, and 
. pig-metal made from it, the ores, &c. are 
‘to be pulverized and calcined in ovens or 
kilns with vegetable fuel and carbonated 
pit-coa] orcoke, and the ore wafhedin water 
ftrongly impregnated with common or 
other falt. ‘The pig metal, or the pig iron 
extracted by: the ufual proceffes, is refined 
and purified with combyftive and phig.

pittive fubstances, with the addition of 
fluxes, in the proportion of three potthds 
to one hundred-weight of pig-mstal. The 
metal fo refined: io: purified by. the additior 
of fluxes in the foltowitig proportions: 
viz. to the refined metal, while in a fluid 
ftate,is to be added Half a poutid of the pre~ 
pared flux; arid to the ufprepared pig. 
metal is added four pounds of the faid 
flux, if required, to difpel the heteroge= 
neous matter. The former procefs tg: 
preferred when the iron is intended for the 
Aneft and belt purpofes, and for making: 
fteel ; as the fluxes: Have the beft effect 
when the metal is-in' contac with the fuek 
that poffeles the lealt quantity of fulphur 
and other pernicious fubftances, that op

MR, WILLIAM BOOND’$(MANCHESTER? 
jor a new Manufacture of Mixed and 
Coloured Cotton Velvsts, Velveteens, andy 
ether Cotton Pile Goods, caramonly cabled. 
Fuftians. ; 
The cotton being properly prepared, 
Mr. B. proceeds to {pin it in the following 
manner: He places a dyed roving, and an 
undyed or coloured roving in the frame of 
a {pinning machine, and {pins two er 
niore rovings together into one thread; 
by this means is obtained a mixture or 
mottled thread or weft, which is weaved 
into cotton velvets, velveteens, &c. After 
the goods are woven, he proceeds to raife 
the pile, fo as to fhew the mixture, by 
cutting the face or tuft of the pieces lon~ 
gitudinally in a frame with knives, as 
fuftians in the grey are ufually cut; then 
he immerges them in lukewarm water, in 
which a {mall quantity of alum is dif. 
folved: they are afterwards dried in a 
ftove or in the open air. When dried, 
the pieces are to be rubbed acrofs or lon~ 
gitudinally with brufhes, and a {tone tg 
taife the pile, and make it knit together; 
fome pieces when they have undergope this 
laft operation are ready for fale; others will 
require farther labour, which is deferibed 
in the {pecification. “The claim made by 
the patentee is the weaving mixed cotton, 
weft, or yarn, into pile goods, and for fi- 
nifhing the fame after they are woven, fo | 
as to make a mixed or mottied pile, fit. 
lar to mixed woollen cloth or kerfeymers, 
which has never been praétifed before en 
thefe kinds of cettpn pile goods.
