Abstract
Disclosed is a pottery greenware material by which a pottery having both productivity and quality can be produced with a high degree of freedom depending on an intended use thereof. The pottery greenware material includes a first greenware material and a second greenware material; both the first greenware material and the second greenware material including, as chemical species, SiO2, Al2O3, and either one or both of K2O and Na2O; and an average particle diameter (D2) of the second greenware material being smaller than an average particle diameter (D1) of the first greenware material.
Claims13
A pottery greenware material comprising a first greenware material and a second greenware material, wherein
- both the first greenware material and the second greenware material comprise, as chemical species, SiO2, Al2O3, and either one or both of K2O and Na2O;
- and
- an average particle diameter (D2) of the second greenware material is smaller than an average particle diameter (D1) of the first greenware material.
A method for producing a pottery greenware material, comprising the steps of:
- mixing a first greenware raw material to prepare a first greenware material having a first average particle diameter (D10),
- mixing a second greenware raw material to prepare a second greenware material having a second average particle diameter (D20), and
- mixing the first greenware material with the second greenware material;
- wherein
- both the first greenware material and the second greenware material comprise, as chemical species, SiO2, Al2O3, and either one or both of K2O and Na2O, and
- after the first greenware material and the second greenware material are mixed, an average particle diameter (D2) of the second greenware material is smaller than an average particle diameter (D1) of the first greenware material.
