A chashaku is a spoon used to scoop matcha from a tea container or utensil and transfer it to a bowl.
Most of them are made of bamboo, but there are other materials such as ivory, bare wood, lacquerware, tortoiseshell, silver, sand and ceramics.
At first, it was a medicine spoon made of gold, silver, sand, tortoiseshell, ivory, etc., and was called chahi.
Juko Murata is said to have used bamboo instead of expensive ivory to create a tea scoop that was wiped with lacquer. I'm here.
Since then, the materials have mostly been bamboo and ivory, but although the shape has not been consistent, most of them have been wiped with lacquer.
Joo Takeno made tea scoops with knots near the kiridome (tomebushi) and knots near the kiridome.
After the Momoyama era, most tea scoops became Nakabushi with bamboo joints in the middle, and it is said that Sen no Rikyu became the standard form of tea scoops.
Also, until Rikyu and Oribe, the lacquer was wiped, but from Sotan and Enshu, tea scoops without lacquer were the standard type.
Bamboo without ivory or knots is called true tea scoop, bamboo with mulberry or knots is called gyo chashaku, bamboo with medium knots, and wooden ones other than mulberry are called grass tea scoops.
