New method of Labelling Glass Bottles t fyc. 55 
These substances are to be mixed with the enamel, the whole 
melted and rubbed down with a certain quantity of essence 
of lavender and essence of turpentine, which have become 
thick by long exposure to the air ; the proportions generally 
used are two-thirds of the former to one-third of the latter. 
This composition is to be applied by means of flat camels* 
hair brushes. For example ; to a portion of the prepared 
enamel of the size of a hazel-nut, is to be added one drop of 
the turpentine and two drops of the lavender, and the whole 
well mixed on a glass pallet; with this mixture a portion of 
the surface of the bottle, rather larger than the intended la- 
bel, is to be covered. When it is almost dry, the surface is 
to be smoothed by a short, thick, but very soft camel's hair 
brush; when it is perfectly dry, it may be readily ascertained 
if the proper proportions have been used; too much turpen- 
tine renders it difficult to remove the enamel where the let- 
ters are intended to be, while too much lavender renders it 
so soft, that the least touch detaches it. 
To write or design on this enamel, all that is requisite is to 
remove this substance from the spots the letters occupy, which 
is readily done by a quill cut like a pen but without a slit, the 
letters or design may be formed by the hand alone, or with 
the aid of a stencil plate. 
The fusion of the enamel, is the last but the most difficult 
part of the operation. However, with a little practice, a per- 
son will always succeed in fusing it by means of an enamel- 
ling lamp; when a number of articles are to be thus labelled, 
a furnace must be used, and the pieces placed in muffles. Af- 
ter the temperature has been raised to the requisite height, 
that is to a red heat, the fire is to be extinguished, and the 
furnace closed, so as to anneal the articles properly.
