Product Details Kiwi Underglaze Cobalt Blue is a ready to paint liquid glaze that has a full palette of vibrant, fluxed colours based upon our ceramic stains. It is suitable for applying directly onto greenware (leatherhard or bone dry) or onto bisqueware. Kiwi Underglaze Cobalt Blue performs well at both earthenware and stoneware temperatures. Firing Range: 1000 – 1250C plus Firing: The usual underglaze technique is to apply the colour onto greenware and then bisquefire at 1000C prior to an application of clear glaze. If applying directly onto bisqueware however, a second optional firing at 1000C will “harden on” the colour prior to glazing. After firing, the colour intensifies and becomes glossy. When left unglazed and fired to around 1000C or more, the colours assume a velvet matt appearance. A good surface for sculptural forms and as a decorating effect where glazing is not essential. Colour should be applied as thinly as possible, in layers, to achieve the desired effect. If water has been lost a little more may be added but be careful not to dilute colour power. Application gives translucent with 1 coat, semi opaque with 2 coats and opaque with 3 coats. Safety: All colours are food safe.
