of the fire. Opake colours require lefs management than 
the tranfparent. A variety of circtnnftances mil ft be at¬ 
tended to in the management of tranfparent colours' 1 ; 
every colour requires gold of a particular finenefs. When 
different colours are intended to be placed befide one ano¬ 
ther, they are kept feparate by a fmall edge or promi¬ 
nency, which is left in the gold for that purpofe, and is 
poliflied along with the enamel. The enamelling upon 
filver is effected nearly in the fame manner as that of 
gold ; but the changes fuftained by the colours upon the 
filver, by the aflion of fire, are much more conGderable 
than when gold is ufed. Copper is not much ufed by 
enamellers, on account of the difficulty which attends the 
attempt to fix beautiful colours upon it. When this 
metal is ufed, the common praftice is to apply a coating 
of opake white enamel, and upon this other-colours which 
are more fufible than the white, A good effect is pro¬ 
duced in toys, by leaving part of the gold bare. For this 
purpofe its furface is cut into fuitable compartments by 
vlie engraver. This, however, is an expenfive method, 
and is for that reafon occafionally imitated by applying 
fmall and very thin pieces of gold upon the furface of the 
enamel, where they are fixed by the fire, and afterwards 
covered by a tranfparent vitreous coating. For painting 
and enamelling glafs, china-ware, &c. See the articles 
Glass, Porcelain, and Pottery. 
Mr. Brougniart deferibes a method of taking off the 
enamel from any toy, without injuring its metallic part. 
For this purpofe, a mixture of common fait, nitre, and 
alum, in powder, is applied upon the enamel, and the 
piece put into the furnace. As foon as the fufion has 
taken place, the piece is fuddenly' thrown into water, 
which caufes the enamel to fly off either totally or in part. 
The part which may remain is to be removed by repeat¬ 
ing the fame operation a fecond time. 
The procefs adopted by the Ruffian filverfmiths, for 
filling up engravings in plate with a black, glaffy, durable 
enamel, and which they rriuft have derived from the Per- 
fians or Indians, is as follows: They take half an ounce 
of (ilver, two ounces and a half of copper, three ounces 
and a half of lead, twelve -ounces of fulphur, and two 
ounces and a half of fal ammoniac. The metals are 
melted together and poured into a crucible, which has 
been before filled with pulverifed fulphur made into a 
pafte by means of water; the crucible is then immedi¬ 
ately covered, that the fulphur may not take fire ; and 
this regulits is calcined over a fmelting fire until the fiu- 
perfluous fulphur be burnt away. This regulus is then 
coarfely pounded, and, with a folutionof fal ammoniac, 
formed into a pafte, which is rubbed clofely into the en¬ 
graving on filver plate. The filver is then wiped clean, 
and fuffered to become fo hot under the muffle, that the 
fubftance rubbed into the ftrokes of the engraving melts 
and adheres to the metal. The filver is afterwards wetted 
with the folutionof fal ammoniac, and again placed under 
the muffle till it becomes red hot. The engraved furface 
may then be fmoothed and poliflied without any danger 
of the black fubftance, which is an artificial kind of 
filver ore (fablerz), either dropping out or decaying. In 
this manner is all the filver plate brought from Ruffia 
ornamented with black engraved figures, &c. 
It is incredible to what a degree of finenefs and delicacy 
the threads of enamel may be drawn by the enameller’s 
lamp. Thofe which are ufed in imitating tufts of feathers 
are fo fine, that they may be wound on the reel like iilk 
or thread. The fiftitious jets of all colours, ufed in em¬ 
broideries, are alfo made of enamel ; and that with fo 
much art, that every fmall piece hath its hole to pafs the 
thread through wherewith it is fewed. Thefe holes are 
made by blowing them into long pieces; which they af¬ 
terwards cut with a proper tool. 
A method of enamelling culinary utenfils, as a fubfti- 
tute for tinning , has been lately invented by M. Rinman, 
of the Royal Academy of Stockholm ; for which fee the 
article Tinninc.
