PLIn order to process the condensation products of phenols and viscous and continuous aildlehydes, as well as permanently insoluble and nitrofusible substances, these preparations are introduced into boxes or pipes made of metal, glass or similar feeding vessels and heated for a longer time under a slightly increased pressure. After the process is completed, these products (castings) adhere more or less strongly to the walls, but the more strongly, the more often a given mold is used, so that it is finally appropriate to use the reflection of the cast, because it is very easy to damage the mold itself or the cast. In order to avoid significant maifaerial strata and time, it is possible to use bottomless forms and to close them by the surface of the plum, which retains passive force in the face of the hardened mass, not acting on the surface of the mass "and has a specific weight. as a conductor of heat and facilitates the regulation of temperature, preventing (the formation of voids (due to overheating) and internal stresses (cracks, deformation) due to local temperature differences. The method of implementing the present invention is as follows: Filling is appropriate a partially liquid reservoir consisting of a dilute aqueous calcium chloride, magnesium chloride, Glauber's salt or similar substances with a suitable him proper weight; they are placed in the openings for the mold, filled with the solidified mass and poured from the outside with the tfo-winding isollii until the level of the solution equals the level of the mass in the mold. In the case of a soybean solution, a non-boiling metallic alloy, such as a Wood alloy or a Rose metal, can be used. e.g. with oil. Thus, it was possible to use solid bodies that melted at a temperature lower than the midnight temperature, and most of the alliiphatic or allromalic hydrocarbons (paraffin, naphthalite and similar materials). The mold is heated in a normal fashion, Cilala's surrounding or conductive heat keeps the force in a liquid state. The surrounding body may harden during the process, which makes it easier to separate from the processed material. Due to the fact that the molds are open, hardened castings can be easily removed. PL
