Basic Operation

Accessories

Ceramic Fiber Shelves

The soft ceramic fi-

ber shelf, which comes

standard with the kiln,

cradles gold and silver

clay pieces. These

shelves are not suitable

for firing glass or ce-

ramics.

Ceramic Fireclay Shelves & Posts

Ceramic fireclay

shelves, available from

Sundance are hard ce-

ramic surfaces on

which to fire ceramics

and glass. Firing glass,

enameling, and ceramic

glazes directly on the

firing chamber bottom

would ruin the bottom.

Shelves can be stacked

using posts.

Glass Separator & Kiln Wash

Glass separator and

kiln wash are mixtures of

finely ground minerals

that will not melt and

fuse together at high

temperatures. They pre-

vent glass and ceramic

glaze from sticking to

fireclay shelves. The

main difference between

glass separator and kiln

wash is that the separator is ground more finely to leave a

smooth back to glass pieces laid on the shelf.

As powders, glass separator and kiln wash have an unlim-

ited shelf life. Do not breathe the powder when mixing.

Caution: If glass separator or kiln wash contact a

heating element, that element will burn out in the

next firing. NEVER apply glass separator or kiln

wash to the ceramic fiber firing chamber.

Haik Brush

The haik brush is used to apply

glass separator to the kiln shelf in a

smooth, thin layer. The smoother

the glass separator, the smoother

the underside of the glass.

Alumina Hydrate

Delicate silver or gold clay shapes may need extra support

during firing to prevent warping. Place these shapes in a thin

layer of alumina hydrate inside a small ceramic bisque bowl.

Do not breathe alumina hydrate.

Stilts

Stilts are points embedded in a ceramic base. The points

separate enameling and glazed ceramics from the shelf.

Enameling Racks

Enameling is the art of firing glass onto metal. The metal

shapes are loaded onto a high temperature wire rack. The

enameled pieces and wire rack are loaded into a hot kiln,

fired for just a few minutes, and removed red hot. To load

and unload the racks safely, use an enameling fork.

The heating element under power is dangerous. Do not

touch the element with anything! Turn the kiln switch off

before inserting an enameling fork into the firing chamber.

Fiber Repair Filler

This is a permanent, high temperature refractory cement

used to repair holes or cracks in the ceramic fiber firing

chamber.

Safety Glasses

Wear clear safety glasses

when cutting or chipping glass.

Wear firing safety glasses when

looking into a hot kiln, such as

when checking the progress of

glass.

Caution: Always wear fir-

ing glasses when viewing

the interior through the optional glass view port.

The wire mesh above is referred to as an enameling rack. An enameling

fork lifts the rack out of the kiln. A stilt separates the piece from the rack.
