A robuchi is a wooden frame that hangs over the hearth of the furnace.
Furnace rims are roughly divided into wooden rims and lacquered rims.
Wood hearth rims are generally used in booths. Early hearth rims were made of wood "Sawaguri" and other names are known, and each has a stamp.
At that time, the wooden edge was washed after each use, so it was also called "washed edge", and water-resistant Sawaguri wood was used.
In addition, there are various kinds of logs such as black persimmon, striped persimmon, mulberry, cherry blossom, red plum, pine, paulownia, and cedar. There is also a tailoring of old materials of shrines and temples.
Bamboo is sometimes used in addition to wood, and there are also those that use square bamboo, and those that stick sesame bamboo or soot bamboo to the wood base.
