Note 287 — Chapter IX · K’ANG HSI BLUE AND WHITE

This defect is noticed by Père d’Entrecolles, who mentions another remedy used by the Chinese potters. They applied, he tells us in section ii. of the second letter, a preparation of bamboo ashes mixed with glazing material to the edges of the plate before the glazing proper. This was supposed to have the desired effect without impairing the whiteness of the porcelain.
