It is a well Known fact that the occurrence or origin of Bog Iron Ore in Hokkaido is quite different from that of Brown Iron Ore in Chosen. Starting from this Consideration, we have observed the heat quantity due to the decomposition of combined water (Warmetonung) by the method of Thermal Analysis for ores of Hokkaido and Chosen, and thus determined the foundamental difference on the property of grains consisting of both kinds of ores. The state of combined water and its decomposition temperature and also the sintering temperature were observed. The differences accompanied on these properties, or any other different nature or property between Bog Iron ore and Brown Iron ore in Chosen will be easily explained by determining the "Warmetonung" as above.
