CO (Carbon Monoxide)

Notas

In the context of ceramics and glaze science, carbon monoxide serves primarily as a potent reducing agent rather than a structural glass-forming oxide. During the firing process, its presence is critical for atmospheric reduction, where it scavenges oxygen from metallic oxides within a glaze or clay body. This reaction fundamentally alters the oxidation states of transition metals, which subsequently dictates the resulting color and crystalline development of the fired surface. As a gas, carbon monoxide permeates the kiln atmosphere, influencing the chemical equilibrium of the melt and affecting the final appearance of sensitive coloring agents such as iron, copper, and cobalt.
