Northcote Earthenware Glazes 500ml Blue Translucent Gloss 1060ºC - 1100ºC
(NCBL)
Brush-on Earthenware glazes, ready to use. Mix of transulcent gloss finish and opaque gloss finish. Firing range 1060ºC - 1100ºC.
Glazes cannot be combined (stirred together) with any assurance that the resulting mixture will be (1) a proper glaze and (2) the colour you thought you would create. Each glaze is a different chemical formula and blending does not necessarily work.
Product and technical information:
• Should always be applied according to the manufacturer’s instructions on the container. Read them before you start.
• Should only be applied to bisque fired clay (unless tested under your studio conditions for raw glazing).
• Should be fired between 1060ºC - 1100ºC (NB cadmium based glazes prefer 1060ºC).
• Should be stirred well before application to ensure even distribution of materials and colourants.
• Should only be applied to dust and grease free surfaces. Sponge surfaces before glazing to be sure they are clean.
• Each coat of glaze should be applied with a large, soft Hake brush. An average coat of glaze is equivalent to the thickness of a coat of house paint applied to a wall.
• Insufficient application of glaze will give ‘stingy’ glaze results, i.e. insufficient colour, gritty surfaces, bare spots and at times, different colours to those expected.
• Application of excessive amounts of glaze will result in glazes running on vertical surfaces and possibly stick the pottery item to the kiln shelf. On horizontal surfaces over application will result in excessive pooling in recessed areas and possible cracking of the glaze/pottery item, or sometimes beading/crawling of the glaze to give an orange peel effect.
• Can be applied over other earthenware glazes for new glaze effects which may differ from the individual effects of each individual glaze.
• Best applied to earthenware and terracotta clays only (not raku, mid-fire, stoneware or porcelain). Coloured opaque glazes perform better on terracotta than transparent glazes because they block out the dark clay colour.
• Should be stored in a cool, dark place to ensure a long shelf life.
• Do not apply glaze to the foot of pots unless firing pottery items on ceramic stilts at temperatures less than 1120ºC.
• Wipe any excess glaze off the foot of pottery while moist and before firing, otherwise pots will stick to kiln shelves during firing.
• Dried glaze cannot be re-wet. It is permanently dry from the binders it contains and will never soften for re-use.
• Wash brushes out in water unless the glaze in them has fully dried.
