Processes; moulding gums and resins.-Condensation products from aldehydes and phenols are hardened by heat treatment in a bottomless mould sealed by a liquid, e.g. a solution of calcium chloride, magnesium chloride, or Glauber salt, or molten mass of specific gravity higher than that of the mass to be hardened. A container is partly filled with the solution &c., the moulds are inserted, and the mass filled in, after which a further quantity of solution is added to the container outside the moulds until its level coincides with that of the mass. The mass may be covered by an inert liquid, e.g. oil.

Casting

A transparent capsule is manufactured by using a lower die case having a substantially semi-spherical inner surface and an upper die cast having a substantially semi-spherical outer surface. The radius of the upper die cast is slightly smaller than that of the lower die cast. Transparent resin in the space between the lower die cast and said upper die cast is uniformly and gradually heated and then cooled in order to harden the transparent resin. Thereafter, the upper die cast is separated from the lower die cast and the transparent resin formed in the shape of a sphere is removed from the die casts.
