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.
