2 Tools to attach ink

1.Ink pots and vermilion pots

Ink pots are used to draw long straight lines accurately on the surface of wood and other materials. One end of the pot thread is tied to the "Karuko", the other is passed through a pond where the ink is stored from the clue, and wrapped around a spinning wheel (see figure). Ink soup is soaked in cotton, etc. and put in the pond, and silk thread is used for the pot thread.

To be used, hold the ink pot on the left hand and stick the needle of "Karuko" to the material to fix one of the japan threads. Once the thread of the required length is pulled out, stop the car with your thumb, hold the thread to the required position with your forefinger to make it nervous, and pick up the thread straight with your right hand and release it. By using the elasticity of the thread in this way, it is possible to draw an accurate straight line regardless of the origin of the material.

Keyaki is mainly used as the material of the ink pot, and the thread is reinforced with pottery and brass. In the past, users were handmade, but now they are often made by professional craftsmen and some plastic products. There are various shapes, some of which have elaborate designs such as sculptures. There are two types of cars: those with handles and those without handles. It is said that carpenters in Kansai mainly use a handle-free format that turns the car by hand and winds the thread, and Kanto carpenters prefer a handle.

The pigment that uses red husk instead of sumi soup is called a red pot. Red husks disappear when washed with water, so natural trees such as polished logs are mainly used for inking when using them as they are without shaving the bark.

Names of each part of the ink pot

2.Ink

Ink sashimi has a spatula shape on one end and a thin stick on the other side. Use it to write a line on the spatula-shaped side and a symbol or character on the rod-shaped side with ink. It is used together with ink pots and vermilion pots.

The material is made of bamboo. The spatula-shaped side is cut vertically thinly to a depth of about 10 to 15 mm in width and about 1 to 2 cm from the tip, and the spatula tip is cut off diagonally. Draw a line along this part along the curve. Skilled people say that interrupts are extremely thin in about 30 to 40 sheets.

3.Yadate

Yatate is a small portable brush case. It consists of an ink holder that stores ink and a pole that stores brushes. It may be used instead of ink, such as when guarding.
