A number of these are placed in one furnace. The following section shows the arrangement (Fig. 16). The positive electrode K can be made of a mixture of anhydrous alumina and carbon pressed into shape and ignited. A mixture of alumina and gas-tar answers very well; or it can even be made of gas-tar and gas-retort carbon. During the operation little pieces of carbon fall from it and would contaminate the bath, but are kept from doing so by the mantle G. This isolating vessel G is perforated around the lower part at g, so that the chlorine gas liberated at K may escape through the tube 0', while reducing gases can be brought into the crucible by the tube 0'. To lessen the electrical resistance and to renew the bath of chloride or fluoride, D. R. Pat. No. 26,962. Fig. 16. bars of carbon, alumina, or magnesia are placed inside the isolating mantle Cr. This process is now being worked on a large scale in Germany, being also used for producing magnesium. There are works at Bremen and Hamburg. M.
