aword, the whole mordait mutt be iut-
'hcicn,iy yellow, frong, and OF an aitrin-
gent tate.
As ioon as The alcm IS d:golved, no time
NUT pe loft In order thar the mordant
may not be fntfered 20 cool. The yarn
IS then put into hollow blocks of wood
ihaped like mortar, into each of which
Z iuch quantity of the sn,ordant has been
!, poured as may be fuficient to molten the
yarn without any OF it being left. AS
( foon as the workman throws the mordant
into the mortar, lie pl,s quantity OF the
yarn into it, and prehes it down with his
hand till it becomes uniformly moitened,
aud the whole cotton yarn has Rruck-
BY this it acquires only pale yellow CO.
iour, which however is durable. 1t is
then hung upon polesin the fun to dry 8
again w4lhed in the Rream, and after
wards dried once more.
BY the yellow dye Of the fumach leaves
the madden dye becomes brighter and
more agreeable; but til. gals damp the
fuperauous yellow, and together with the
alum prepare the yarn for It's colour.
Some dyefs however omit the uie Of thcie
leassfes altogether, and prepare their NOR
7lant from gals and alum only by GrR boil
ing the gals III due proportion with the re-
quite quantity of water, then diAolving
the alum with boiling water in faparate
veliel, afterwards pouring both liquors to-
gether into tub, and faffsting the cotton
TO remain in them al hour, or an hour ana
a half; afer which It'll dried gradually,
then wafh ed, & again dried once more. By
this Procefs the yarn acquires dirty red
din colour.
The next part Of the procefs is to pre-
pare the madden dye. The madden,
ground TO fine powder, is fpreai ouy in
Large troughs, and into each trough is pour
ed large cup full OF iheep's blaod, which
Is the kind that can be procured with the
greatef facility by the dyers. The mad
der mutt BE arongly mixed inaitcby means
ofthe hand, and then fsnd fome hours 4.
order TO he thoroughly ioakei by it. The
Liquor then aiiumes a dark red appear
ance, and the madden in boiling yields
more dye.
After this procefs wafer is made no, in
large KETTLES, fixed in brick work; and as
ssoon as It is warm the prepared red dye lis
put into It, III the proportion of a poundso
every pound of cotton. The dyeis then
uttered TO boil irongly and when it is
enough, which may be tried on cotton
threads, the fire is removed from under the
kettle, andthe prepared cotton is dcpoiired
! near it. The dyer places hrnlelf on I'll,
edge OF the brich-work that enciofes tn.
: kettle; dips the cotton yarn, piece by piece
INTO the dye; turns it round, backward,
and forwards; preties it little with h..
hands ; and lays each piece one after the
other, In pals itanding ready for the pur-
pole. .Asfoon as all the cotton has rece;y.
cd the hrtt tint, it ishung up to dry: as
the red, however, is fill too dull, n. var
which has been already died once, and be-
come dry, is put once more into the dive
tng-kettle, ard NUT be left there TO teeth
Ior three hours over itrona ise, by which
Il acquires that beautiful dark red colour
which IS 10 much eGeemed in the I'urkib
yarn. The yarn is now taken from the
dye with ticks; the fuperAuous dive which
adheres to 1t is ihaken off; the hanks are
put In order, and hung up, one after ano-
.nef' to cry. When it is thoroughly dry
1t is ~aihed in the pure Rream and again
cried. The only fault of the Aiirscan
Overs is, that the colour is lometimes
brighter and fometimes darker, probably
becauie they do not pay fafTicient attention
10 the proportions, or becaufe the .rnadder
is not always Of the fame goodnefs.
In the iatt place, the abovement;oned
ioda tiSalakar) is diaolved viii, boilino
water IN tubs defined for that purooC.
and 1t is ufnal here to allow twenty pounds
OF ioda to forty pounds of cotton. or half
