Nontoxic Fired Glazes
~
are glazes that are deemed safe for use by children,
pregnant women, older people and anyone who is health conscious. Non-toxic
glazes do not contain lead, cadmium or other chemicals that are considered
toxic to the human body.
Duncan Crackle glazes are special effect glazes which crackle and craze giving an antique look to your finished ceramic piece. After firing you may wash the piece with dark acrylic color to show the crackles to their best advantage. When color is washed into all cracks, wipe the surface with a clean damp cloth to remove remaining color and leave the glaze shiny. Not recommended for use on food containers due to crackled surface.
Duncan Crystal glazes are beautiful glazes full of colored crystals which flow during firing. Paint the glaze on the ceramic bisque for the first two coats, then stir in the crystals for the final coat. Place more crystals near the top of the piece and fewer near the bottom where they may run off. Not recommended for food containers due to uneven surface which may harbor bacteria.
Duncan Envision glazes are safe for dinnerware and other food containers. They come in a variety of both translucent and opaque colors, and flow very little during firing. Three coats of Envision glazes must be applied with even strokes to completely seal and avoid brushstrokes in the final product. Use Envision glazes on plates, bowls, cups, cannisters, teapots, etc.
Duncan French Dimensions come in squeeze tubes for ease of application. They are non-moving and produce a raised effect over and under non-moving glazes. Great for creating a 'stained glass' effect. Paint your design outline on greenware, and fire to cone 04. Then 'fill-in' the design with Envision glazes and fire to cone 06. Fun, easy and so beautiful!
Duncan Satin glazes produce a soft sheen, not the hard shine so common in ceramics. Some are transparent, but most are opaque. Satin glazes are safe for food containers.
Mayco Crystalite glazes with beautiful flowing crystals are great for schools or institutions.
Mayco Elements are gorgeous new non-toxic glazes in natural earth tones. Surfaces vary from gloss to matte, with subtle variations in each color for a truly unique look. Now labeled as dinnerware safe.
Mayco Elements Chunkies are Elements with Crystals. During firing the crystals spread out to produce a burst of color for a truly unique look. Now labeled as dinnerware safe.
Mayco Pottery Cascades produce special effects when used in combination with other non-toxic glazes. Apply Cascade over or under non-toxic glaze to create spectacular effects. Not labeled as dinnerware safe.
Mayco Pottery Coats simulate other clay bodies such as stoneware and terra cotta. For best results, use as a base for other non-toxic glazes for interesting glaze combinations and techniques. Not labeled as dinnerware safe.
Series 2000 glazes provide a tough, durable and craze resistant surface. The non-flowing characteristics are great for Majolica, water coloring, marbling, glaze butting, decorative brushstrokes, antiquing, stenciling, sponging, spattering or almost any other ceramics technique. Food safe.
Cautionary Glazes
Because they do contain lead or other toxic
materials, please remember that these professional glazes should not be used by
children in schools or in situations where supervision is required. When using
these products use caution. Wash hands frequently, do not put your hands in
your mouth, do not eat or drink around these products and do NOT use your mouth
to pull a nice point on your paint bristles!!! (gross!) Do not stay in an
enclosed room with your kiln during firing of these toxic
products.
Cautionary (Professional) fired products include the ASTM
D-4236 CAUTION seal (similar to ACMI CL standards) on the label. Products in
this section are certified to be properly labeled with information on safe and
proper handling and use. These products have also had a toxicological
evaluation by a medical expert, and labels disclose any known health risks
associated with improper handling of the products.
Due to changing FDA
and Consumer Product Safety Commission regulations, always refer to the product
label for the most current safety information.
We recommend that you DO
NOT apply leaded and non-toxic glazes to the same piece of bisque. The
different expansion/contraction of these two glazes could cause the piece to
crack or break.
Duncan Red-Coats Opaque
Underglazes produce intense, opaque reds when fired under GL612
Diamond Clear Glaze. Red Coats may be used for brushing, sponging and most
decorative brushwork. Keep brushes and hands clean and free of oil and salt
when working with Red-Coats. Apply Red Coats to bisque
only.
Note: Red Coats have been discontinued. For great red
underglazes try non-toxic Concepts underglaze for bisque or CoverCoats
underglaze for greenware.
Duncan Antique and Art glazes are specialty glazes which fire to a wide variety of finished looks. Antique Blue is unique, a rich blue with gold highlights. Art glazes range from solid to translucent, satin to glossy, some with flecks of color, some with color streaks. All are beautiful.
Duncan Crystaltone glazes are beautiful glazes full of different colored crystals which flow during firing. Paint the glaze on the ceramic bisque for the first two coats, then stir in the crystals for the final coat. Place more crystals near the top of the piece and fewer near the bottom where they may run off. If you aren't careful you could end up with glaze 'feet' on the bottom of your piece, or the glaze could flow off the piece and onto your stilt and kiln shelf.
Duncan Gloss glazes are very shiny and bright, they come in a wide variety of colors, many of them nearly the same as the Envision colors. Gloss glazes are not recommended for food containers and flow freely during firing. Use gloss glazes on candle holders, vases, the outsides of teapots and other purely decorative items.
Mayco Jungle Gem Crystal glazes consist of a base glaze with granules of contrasting glazes. During firing, the crystals spread out to produce a burst of color. Use a fan brush to paint the glaze on the ceramic bisque for the first two coats, then stir in the crystals for the final coat. Place more crystals near the top of the piece and fewer near the bottom where they may run off (forming feet!). The labels for these glazes contain cautionary warnings.
Mayco Exotic glazes. Each glaze is so strikingly different that 'Exotic' is the only word that adequately describes them. Some shift from gloss to matte to develop a frosted look, some produce several colors, some contain specks. No two pieces will look exactly alike.
Overglazes - Gold, White Gold, Halo Gold, Mother of Pearl and Mardi Gras
Overglazes are
primarily accent products applied over a fired glaze, then
kiln fired at a relatively low temperature (cone 018 - 020). Be sure underlying
glaze is overglaze compatible. When using precious metals and lusters on the
same piece, apply and fire the metallics first.
Note: always
apply with a brush that is designated solely for use with each specific
metallic overglaze to avoid contamination. Do not use your Mother-of-Pearl
brush on Gold, or vice versa. Clean brushes with OA901 Essence which is also
reserved for the type of overglaze applied. Use a permanent marker to write the
number of the gold or luster your Essence goes with and have a different bottle
of Essence for each overglaze.
When fired these metallic overglazes
yield different shades ranging from yellow gold to white gold and assume a
sheen similar to the underlying glaze. If the glaze is glossy the overglaze
will be also.
The luster is a translucent product that gives underlying
colors the iridescent look of mother-of-pearl.
Non-fired Paints
Non-fired products are used exclusively on cone 04
bisque and are for decorative purposes only. Apply a sealer to complete your
piece unless otherwise noted on each container. Such pieces should be cleaned
with a lightly dampened sponge, they are not dishwasher safe and should never
be immersed in water.
Non-fired products are not
considered food safe and should not be applied to cups, mugs or dishes which
will be used and washed regularly.
Always clean bisque with a damp sponge to remove clay dust prior to application of color.
Sparklers Brush-on Glitter are premixed glitter colors which are permanent and won't flake or rub off. They work on almost any craft surface except fabric. They can be applied directly on the surface and over other acrylic colors. Self sealing.
Ultra Metallics are non-toxic, water-based metallic colors. Their colors are bright, won't tarnish and gleam like real metals. They can be mixed together and with other water-based nonfired colors to create more metallic colors and are self-sealing.
Water-based Antiquing Gels are a revolutionary breakthrough in antiquing - no need for solvents! The rich, thick and creamy formula results in easy, no-drip application and rich, lustrous antiqued finishes. The water-based formula cleans easily with water and produces no odor or fumes.
