SEALING See also:

WAX . In See also:medieval times, when the See also:principal use of sealing wax was for attaching the impression of See also:seals to See also:official documents, the See also:composition used consisted of a mixture of See also:Venice See also:turpentine, beeswax and colouring See also:matter, usually See also:vermilion. The preparation now employed contains no wax. See also:Fine red See also:stationery sealing wax is composed of about seven parts by See also:weight of shellac, four of Venice turpentine, and three to four of vermilion. The resins are melted together in an earthenware pot over a moderate See also:fire, and the colouring matter is added slowly with careful stirring. The See also:mass when taken from the fire is poured into oiled See also:tin moulds the See also:form of the sticks required, and when hard the sticks are polished by passing them rapidly over a See also:charcoal fire, or through a spirit See also:flame, which melts the superficial film. For the brightest qualities of sealing wax bleached See also:lac is employed, and a proportion of perfuming matter—storax or See also:balsam of See also:Peru—is added. In the commoner qualities considerable admixtures of See also:chalk, carbonate of See also:magnesia, baryta See also:white or other earthy matters are employed, and for the various See also:colours appropriate See also:mineral See also:pigments. In inferior waxes See also:ordinary See also:resin takes the See also:place of lac, and the See also:dragon See also:gum of See also:Australia (from Xanthorrhoea hastilis) and other resins are similarly substituted. Such waxes, used for bottling, parcelling and other coarser applications, run thin when heated, and are comparatively brittle, whereas fine wax should soften slowly and is tenacious and adhesive.
