The authors made experiments on producing cast iron with cast-in-steel inserted, which is coated with machine oil, red lead, water glass and silicon powder, or with such cast-in-steel as is covered with oxidation scale or hydration scale inserted. The results obtained are as follows : — 1. In all cases, the results are worse than in case of using naked and polished steel cores. 2. Worse adherent conditions were shown, in particular, when steel-cores coated with machine oil, red lead or water glass were used. 3. While it has been a general method to use machine-oil coated cores to prevent blow occurence, it proved to be a bad one by our experiment.
