Iceberg Blue Amaco Velvet Underglaze V328

Iceberg Blue Velvet Underglaze is a light blue color that is powder blue at cone 05, slightly darker at cone 5, and maintains its light blue shade up to cone 10. A clear glaze over Iceberg Blue tends to lift the color out slightly, lightening it.

Safety Warning

Tableware producers must test all finished ware to establish dinnerware status, due to possible variations in firing temperature and contamination.

Underglazes are vibrant, semi translucent, fluxed colours which are very versatile and offer three alternative techniques:

1.When left unglazed and then fired 1000 deg.C - 1100degC, they give semi matt surfaces to simulate cloth and fur textures. With slightly higher firing they assume a slight sheen. Glazing is not essential allowing permanent decoration of finely detailed modelling without having the detail rounded away by subsequent glazing.

2.When used in normal Underglaze fashion they can be glazed by dipping , spraying , or a transparent brush on glaze can be used. The colours intensify and give glossy results.

3.They can be used majolica fashion on the unfired glaze, the flux content of the colours giving more predictable results.

Velvet Underglazes fire true to colour as applied from the jar and can be mixed to give to give many more different shades. They tolerate a wide firing range and can be used on porcelain and stoneware with the exception of orange and red. Velvets vitrify at about cone 4 - 6 and can be used on clay, Bisque or on the glaze and can be applied by brushing, sponging or spraying.
