History of casting
Cast history is old and it will be said around B.C. 4000 that it started in the Mesopotamia.
Copper is melted, it pours into a model and it is called beginning to have built various vessels.
A casting could be called one of the oldest things in man's craftsmanship.
It is around hundreds of years ofbefore B.C. that the technology of the production of a casting got across to Japan.
When it entered in the 1st century, dotaku, a lead mirror, a sword, etc. came to be built, and when the Nara period came, a Buddha statue, a bell, etc. were built briskly.
It is called middle of the Heian period or subsequent ones that the production of a casting spread in various places.
The cause by which a casting came to take the form of a present-day industry is the Industrial Revolution which occurred in Britain about the middle of the 18th century.
With development of factory industry, a casting came to be widely adopted into machine civilization.
In Japan, the last stage of the end of the Edo period comes and movement toward modernization becomes active.
The government introduced technology from the Netherlands and built the cupola (smelter).
This became a forerunner to modernization.
The casting extended money, accessories, a farming implement, a production machine, construction material, and its use range.
The material according to development of foundry technique came to be used bronze, iron, aluminum.
It seems that it is as old as foundry technique, it is new, and there is no technology which is continuing developing.
