Amaco Low-Fire Gloss
Cone 06-04. AMACOŽ Gloss Glazes fire to a smooth, glossy finish at a witness Cone 05 (1915°F, 1046°C). Always slow fire lead free glazes for best results. AmacoŽ Gloss Glazes flow slightly during firing to a high gloss finish, while correcting most application imperfections. Good results can be obtained on all AMACOŽ ceramic clay or slip.
For a clear, all-over, covering glaze, you have a choice of LG-9 lead containing glaze or LG-10 lead free. LG-10 has a smooth and high gloss surface. Make sure it reaches a mature witness Cone 05 (1915°F, 1046°C). You might apply it thinner than usual for best results. Two coats are usually enough.
LG-9 Clear glaze is a lead-containing glaze. Precautions in handling should be taken. Read label before using. LG-9 is a beautiful glaze and is very forgiving in firing, however, for best results a mature Cone 05 (1915°F, 1046°C) firing is recommended.
Clear glaze can be used over the AMACOŽ LUG series, Velvet, Velvet-1-Strokes, Designer Velvet and over the GDC Gloss decorating colors. When gloss decorating colors are used over bisque, they need a clear gloss over them, which is applied at the same time and fired once. LG-11, Opaque White, is the whitest and most opaque of our white glazes. It can be used for the Majolica technique (see Underglazes/Gloss Decorating Colors). Apply LG-11 White on a mature Cone 04 (1940°F, 1060°C) bisque. Then paint your design using GDC Gloss Decorating Colors over the unfired white glaze. Fire when your design is done. There is no need for a clear glaze over the GDC design when you have a white glaze as a base.
All AMACOŽ glazes are formulated for brushing, however if pouring, sponging or dipping techniques are used for lead containing glazes, we recommend using rubber gloves, so that glaze will not get on your hands and run the risk of hand to mouth contamination and ingestion of lead.
LG-53, LG-56, and LG-66 are lead/cadmium red glazes. Brilliant Red, Orange, and Yellow glazes belong to a family of ceramic products, which are traditionally temperamental. To insure the ultimate in color development from AMACOŽ LG-53, LG-56, and LG-66, be very careful that these glazes are not over-fired. Their limit is Cone 06 (1830°F, 999°C), preferably by cone observation. If other means of end point measurement are used, please verify the accuracy of such devices by comparing them to cones. This type of glaze must be applied heavily -- about twice as thick an unfired coat as is usually necessary for more conventional glazes. These products must be applied to bisque ware that has been fired to a mature Cone 04 (1940°F, 1060°C).
An important factor in the success of these glazes is the need for a fast firing (3-4 hours) to no higher than Cone 06 (1830°F, 999°C) and their requirements of generous air supply during firing. The kiln should be stacked with plenty of air space around the pieces to permit circulation. Do not crowd the kiln. Fire with peepholes left open during the entire firing cycle. Sometimes the door of the kiln may be left ajar, anything to assure a plentiful oxygen supply.
Finally, the proximity of copper green glazes will adversely affect the red glazes. Pieces with green-colored glaze should be kept as far removed as possible from the red glazes. When all of these points of advice are carefully observed, we are confident that the brilliant results expected of AMACOŽ products will be achieved.
AmacoŽ Gloss Glazes are available in liquid (pint or gallon) or one pound dry. The three White gloss glazes from AmacoŽ offer a variety of finishes when fired. DG-11 Deco White fires to a pure white, LG-11 fires white, and F-11 White fires to an off-white.
** All LG Series glazes are lead free in liquid and dry form except LG-9, LG-32, LG-53, LG-56, and LG-66.
