Reason for warmth
Mikagi Stone Heat Stormability
Mikaga Stone is a kind of stone with a kind of fire rocks, and it is a stone that has cooled deep and solid.
It is very hard in the stone and is characterized by less aging.
Mikagi stone melting point is very high at 1000-1200 ° C and can store many heat. That is, it is a substance with high heat storage.
Stone materials are produced by many places in Japan and many areas around the world and are about 300 types.
Here is a photo when I actually went to the quarry quarter of Mikaig Stone and meeting with the local people. All rockboards that look back are Mikaig Stones.

Mikaga stone is a natural material used to keep warmth, as there is a word "rice (rice ball)".
It has been attracted attention since ancient times for its heat storage, but it is mostly used as a structure, such as a tombstone and a plate stone for architectural construction.
Heat heat from the plate
Heat is accumulated by warming ON-DISH in the range.
The heat stored in ON-DISH is gradually dissipated, but its heat is the principle that dishes are kept warm.
