In order to test further the factors contributing to production of uniform sponge, a reactor and furnace capable of making 500 pounds of titanium per batch is now under construction. The operator is looking into the furnace shell and the three cylindrical containers for holding molten magnesium chloride to be tapped from the reaction chamber during the reduction are shown at the left."]](https://d8e7jbdw4fu0e.cloudfront.net/4452/60f14570-c1ff-11ee-ab27-e56e0f1cdedf-wyYK66V.lg-nt@2x.jpg)
