Method of preparing Talloiv Candles 
grise obtained was in proportion to the copper corroded; 
and what proves that this method is more advantageous, 
is, that all the manufacturers have abandoned the old 
method and adopted the new.*

On the Method of preparing Tallow Candles with 
Wooden Wipks. Bij Professor Medicus of Heidel- 
berg. \ 
“FOR several years past tallow candles with wooden 
wicks have been prepared, in large quantities, by the 
candlemakers at Munich, and much used in that neigh- 
bourhood. I have burnt them during the whole winter, 
and never wish to use any other kind, as they are attend- 
ed with several advantages which common tallow candles 
do not possess. They afford about the same quantity of 
light as a wax candle; burn also with great steadiness 
and uniformity, and never crackle or run. The candle- 
makers here keep the method of preparing these candles 
as secret as they can ; but I shall communicate to the 
public what I have been able to learn respecting the pro- 
cess. 
“ The only difference between these candles and the 
common tallow candles is, that the ground work of the 
wick consists of a very thin slip of wood, bound round 
to a considerable thickness with very fine unspun cotton; 
but in such a manner that the size of the wick does not 
much exceed that of the wick of a common candle. The 
* There are no large manufactories of verdigrise at Montpellier ; but each 
family makes a certain quantity, and the operations are in general performed by 
wcnnen.
