MOULD, or Mold, in the mechanic 
arts, &c. a cavity cut with a design to give 
its form or impression to some softer matter 
applied therein, of great use in sculpture, 
foundery, &c. The workmen employed in 
melting the mineral or metallic glebe dug 
out of mines, have each their several moulds 
to receive the melted metal as it comes 
out of the furnace ; but these are different 
according to the diversity of metals and 
works. In gold-mines tliey have moulds 
for ingots ; in silver-mines, for bars ; in 
copper and lead mines, for pigs or salmons ; 
in tin-mines, for pigs and ingots ; and in 
iron-mines, for saws, chimney-backs, anvils, 
cauldrons, pots, and other large utensils and 
merchandizes of iron, which are here cast as 
it were at first hand. 
Moulds, in the manufacture of paper, 
are little frames composed of several brass 
or iron-wires, fastened together by another 
wire still finer. Each mould is of the big- 
ness of the sheet of paper to be made, and 
has a rim or ledge of wood to which the 
wires are fastened ; these moulds are more 
usually called frames, or forms. 
Moulds for leaden bullets, are little iron- 
pincers, each of whose branches terminates 
in an hemispherical concavity, which when 
shut, form an iutire sphere ; in the lips or 
sides where the branches meet, is a little jet 
or hole through which the melted lead is 
conveyed. 
Moulds, glazier’s. Tire glaziers have 
two kinds of moulds, both serving to cast 
their lead. In the one they cast the lead 
into long rods or canes fit to be drawn 
through the vice, and the grooves formed 
therein ; this they sometimes call ingot- 
mould. In tlie other they mould those little 
pieces of lead a line thick, and two lines 
broad, festened to the iron-bars ; these may 
be also cast in the vice. 
Moulds, among plumbers, are the tables 
whereon they cast the sheets of lead. 
These they sometimes call simple tables ; 
besides which they have other real moulds 
wherewith they cast pipes without sol- 
dering. 
Moulds, used in basket-making are very 
simple, consisting ordinarily of a willow, or 
osier, turned or bent into an oval, circle, 
square, or other figure, according to the 
ba.skets, panniei-s, hampers, hats, and other 
utensils intended. On these moulds they 
MOU 
make or more properly measure all their 
work, and accordingly they have them of ail 
sizes, shapes, &c. 
Moulds, among tallow-chandlers, are of 
two kinds ; the first for the common dipped 
candles, being the vessel wherein the 
melted tallow is disposed, and the wick 
dipped ; this is of wood, of a triangular 
form, and supported on one of its angles, so 
thaUt has an opening of near a foot at top ; 
the other, used in the fabric of mould can- 
dles, is of brass, pevvter, or tin ; here each 
candle has its several moulds. See Can- 
dle. 
Mould, among gold-beaters, a certain 
number of leaves of vellum, or pieces of 
guts, cut square, of a certain size, and laid 
over one another, between which they put 
the leaves of gold and silver, which they 
beat on the marble with the hammer. They 
have four kinds of moulds, two whereof are 
of vellum, and two of gut ; the smallest of 
those of vellum consists of forty or fifty 
leaves, the largest contains an hundred ; 
for the, others, each contains five hundred 
leaves. The moulds have all their several 
cases, consisting of two pieces of parch- 
ment, serving to keep the leaves of the 
mould in their place, and prevent their 
being disordered in beating. 
Mould, in agriculture, a loose kind of 
earth, every where obvious on the surface 
of the ground, called also natural or mo- 
ther-earth ; by some also loam. 
MOULDINESS, a term applied to bo- 
dies which corrupt in the air, from some 
jiidden principle of humidity therein ; and 
whose corruption shews itself by a certain 
white down, or lanugo, on their surface, 
which, viewed through a microscope, ap- 
pears like a kind of meadow, out of which 
arise herbs and flowers, some only in the 
bud, others full blown, and others decayed, 
each having its root, stalk, and other parts. 
MOULDING, any thing cast in a 
mould, or that seems to have been so, 
though in reality it were cut witli a chissel, 
or the ax. 
Mouldings, in architecture, projectures 
beyond the naked W'all, column, wainscot, 
&c. the assemblage of which forms cor- 
niches, door cases, and other decorations of 
architecture. 
MOUNTAINS, stupendous elevations of 
earth and other substances, in some cases 
coeval with creation, and in others the pro- 
duce of subterraneous motion caused by 
tire and confined vapours.
