Of Raw Materials

Category: On the domestic and political economy of manufactures

210. Although the cost of any article may be reduced in its
ultimate analysis to the quantity of labour by which it was
produced; yet it is usual, in a certain state of the manufacture
of most substances, to call them by the term raw material. Thus
iron, when reduced from the ore and rendered malleable, is in a
state fitted for application to a multitude of useful purposes,
and is the raw material out of which most of our tools are made.
In this stage of its manufacture, but a moderate quantity of
labour has been expended on the substance; and it becomes an
interesting subject to trace the various proportions in which raw
material, in this sense of the term, and labour unite to
constitute the value of many of the productions of the arts.

211. Gold leaf consists of a portion of the metal beaten out
to so great a degree of thinness, as to allow a greenish-blue
light to be transmitted through its pores. About 400 square
inches of this are sold, in the form of a small book containing
25 leaves of gold, for 1s. 6d. In this case, the raw material, or
gold, is worth rather less than two-thirds of the manufactured
article. In the case of silver leaf, the labour considerably
exceeds the value of the material. A book of fifty leaves, which
would cover above 1000 square inches, is sold for 1s. 3d.

212. We may trace the relative influence of the two causes
above referred to, in the prices of fine gold chains made at
Venice. The sizes of these chains are known by numbers, the
smallest having been (in 1828) No. 1, and the numbers 2, 3, 4,
etc., progressively increasing in size. The following table shews
the numbers and the prices of those made at that time.(1*) The
first column gives the number by which the chain is known; the
second expresses the weight in grains of one inch in length of
each chain; the third column the number of links in the same
length; and the last expresses the price, in francs worth
tenpence each, of a Venetian braccio, or about two English feet
of each chain.

Venetian gold chains
Price of a Venetian
Braccio, equal to
Weight of Number of links two feet 1/8 inch
No. one inch, in grains in one inch English
0.44 98 to 100 60 francs
1.56 92 40
1 1/2.77 88 26
2.99 84 20
3 1.46 72 20
4 1.61 64 21
5 2.09 64 23
6 2.61 60 24
7 3.36 56 27
8 3.65 56 29
9 3.72 56 32
10 5.35 50 34
24 9.71 32 60

Amongst these chains, that numbered 0 and that numbered 24
are exactly of the same price, although the quantity of gold in
the latter is twenty-two times as much as in the former. The
difficulty of making the smallest chain is so great, that the
women who make it cannot work above two hours at a time. As we
advance from the smaller chain, the proportionate value of the
work to the worth of the material becomes less and less, until at
the numbers 2 and 3, these two elements of cost balance each
other: after which, the difficulty of the work decreases, and the
value of the material increases.

213. The quantity of labour expended on these chains is,
however, incomparably less than that which is applied in some of
the manufactures of iron. In the case of the smallest Venetian
chain the value of the labour is not above thirty times that of
the gold. The pendulum spring of a watch, which governs the
vibrations of the balance, costs at the retail price two pence,
and weighs fifteen one-hundredths of a grain, whilst the retail
price of a pound of the best iron, the raw material out of which
fifty thousand such springs are made, is exactly the same sum of
two pence.

214. The comparative price of labour and of raw material
entering into the manufactures of France, has been ascertained
with so much care, in a memoir of M. A. M. Heron de Villefosse,
Recherches statistiques, sur les Metaux de France.(2*) that we
shall give an abstract of his results reduced to English
measures. The facts respecting the metals relate to the year

215. The following is stated by M. de Villefosse to be the
price of bar-iron at the forges of various countries, in January,

per ton
L s. d.
France 26 10 0
Belgium and Germany 16 14 0
Sweden and Russia, at Stockholm and St Petersburg 13 13 0
England, at Cardiff 10 1 0

The price of the article in 1832 was 5 0 0

M. De Villefosse states, that in France bar-iron, made as it
usually is with charcoal, costs three times the price of the
cast-iron out of which it is made; whilst in England, where it is
usually made with coke, the cost is only twice the price of

216. The present price (1832) of lead in England is L13 per
ton, and the worth of L1 of it manufactured into

Milled sheet lead becomes Ll.08

The present price of cake copper is L84 per ton, and the
worth of L1 of it manufactured into

Sheet copper becomes L1.11


1. A still finer chain is now manufactured (1832).
