Glaze a glasslike substance comprised of three basic ingredients: silica, flux, and alumina – Basic Ingredients in Glazes Silica referred to as the former. This is most commonly found in sand – Flux reduces the temperature at which silica melts – stabilizes the glaze to keep the glaze from running off the piece Alumina – Glaze Related Terms oxides or commercial colorants, applied before glaze application Underglaze – Overglaze a glaze designed to go over another glaze after the piece has been fired once – Stains-pigments used for coloring clay bodies and glazes. Engobe slip that contains colorants – Luster a decoration that creates a metallic to a glazed surface – a compound used coloring clay bodies and glazes it is comprised of oxygen and other – elements Carbonates a compound used coloring clay bodies and glazes it is comprised of carbon and – other elements Colorant a compound or element that can be added to create color in clay, slip, and glaze – Opacifier an element that can be to glaze to make a glaze opaque – Translucency glaze that allow light to pass through – Matt dull surface in glaze – Glossy shiny surface in glaze – GLAZE APPLICATION
