ART. XII. — FORMULAE FOR THE PREPARATION OF 
SEALING WAX. 
By F. X. Potting er. 
Mr. Pottinger, of Triesch, recommends the following for- 
mulae for the preparation of sealing wax : — 4 ozs. of Vevfi- 
tian turpentine are melted with 7 ozs. of shell-lac in an 
earthenware vessel over a slight charcoal fire. Then 2§ 
ozs. of cinnabar and \h drachm of carbonate of magnesia 
are to be mixed with oil of turpentine into a thick paste ; 
and having previously added to the first mixture 2\ ozs. 
dry cinnabar, the paste is immediately added ; the whole 
being constantly stirred until bubbles arise, when the mix- 
ture is removed from the fire and stirred until the bubbles 
disappear. The mass is then poured into tin moulds, the 
interior of which must be greased with oil of almonds. 
When the sticks are hardened they are polished by being 
quickly drawn through a charcoal fire or spirit flame. 
The following formulae are warranted. 
Fine Red. — 4 ozs. Venitian turpentine, 7 ozs. shell-lac, 
4 ozs. cinnabar, 1 1 drachm magnesia with oil of turpentine, 
p Fine Red, No. 1. — The same formula, except 3| ozs. 
cinnabar instead of 4. 
Red, No. 2. — 4 ozs. Venitian turpentine, 6£ ozs. shell-lac, 
h oz. colophony, 2\ ozs. cinnabar, \\ drachm magnesia and 
oil of turpentine. 
Red, No. 3. — 4 ozs. Venitian turpentine, 6 ozs. shell-lac 
I oz. colophony, if oz. cinnabar, &c. 
Red, JVb. 4. — Turpentine and shell-lac like No. 3, colo- 
phony and cinnabar each J I oz., magnesia, &c. 
Red, No. 5. — 4 ozs. turpentine, 5h ozs. shell-lac, l£ oz. 
colophony, H oz. cinnabar, magnesia, &c. 
Fine Black, No. 1. — 4£ ozs. Venitian turpentine, 9 ozs. 
shell-lac, h oz. colophony, lamp black mixed with oil of
