Sealing Wax
Sealing-Wax does not now contain any wax, as its name would imply. Coarse varieties are made from resins coloured by the thorough incorporation with the melted material of red-lead, vermilion, or other pigment according to the colour desired, the sealing-wax being cast in moulds and allowed to cool. The better varieties contain shellac in place of the resin.
