* Pit Furnace - It is possible to distribute temperature time-uniformly and prevent heat loss because of it’s structure – digging and installing circular pit and then inserting an heated elements from top.

* Bell furnace - It is easy to put in and out heavy materials because it is a structure of bell-shaped resistant-furnace covering an heated elements. Since a metallic retort (such as Sus, Inconel and etc.) covers heated elements and heat it, it takes an advantage on even distribution temperature
