The traditional ceramic industry has recently witnessed increasing interest in the obtainment of inclusion pigments to stabilize at firing temperature and in the action of molten glass’ unstable chromophores such as hematite or cadmium sulphoselenide. This work focuses on the optimization of the synthesis of hematite-silica inclusion pigment. To improve the inclusion efficiency a coprecipitation route was chosen. The use of various precipitant agents (NaOH and NH4OH), and mineralisers were analyzed

Abstract
The traditional ceramic industry has recently witnessed increasing interest in the obtainment of inclusion pigments to stabilize at firing temperature and in the action of molten glass’ unstable chromophores such as hematite or cadmium sulphoselenide. This work focuses on the optimization of the synthesis of hematite-silica inclusion pigment. To improve the inclusion efficiency a coprecipitation route was chosen. The use of various precipitant agents (NaOH and NH4OH), and mineralisers were analyzed
