A nerikomi Tokoname teapot by Shunzan. Shunzan is a true master at 'nerikomi', 'nerikomi katto', and 'tochiri' techniques. Nerikomi is the technique of mixing colored clays together to create a marbling appearance on the teapot. 'Nerikomi katto' is a cut/slicing technique that changes the dynamics of the marbling on the teapot. The other technique 'tochiri' is a highly skilled carving technique. To make a tochiri pattern on a teapot the potter turns the teapot on a wheel and uses a sharp ceramic carving spatula to make small indentations around it. Creating these techniques on a teapot is time consuming and can only be acheive by a highly skilled potter such as Shunzan.
