Ceramic seal

Only high temperature ceramic seals should be used.

(Ceramic seal C – Order No. 090-012-60)

Multiple uses are only suitable when the muffle base is very

smooth. Do not reuse more than three (3) times.

Ceramic crucible and crucible electrode

Two sizes of ceramic crucibles can be used when casting

with alloys.

The small crucible Order No. 090-161-00 can be used for up

to 36 grams of non-precious metals and for up to 45 grams

of precious metal alloys.

The large crucible Order No. 090-161-50 can be used for

a maximum of 54 grams of non-precious alloys and a

maximum of 95 grams of high gold containing alloys.

Attention: Precious metal reduced alloys have a lower

specific weight, therefore, the maximum melting weight is

clearly reduced when compared to high gold containing

alloys.

Use a separate ceramic crucible for every alloy!

The crucible electrode should also only be used for one

alloy.

Repeated use of the ceramic crucible for up to 40 times is

possible, depending on the alloy being used.

The ceramic crucible cannot be cooled down in water after

casting (danger of breakage). Without cool down, the

crucible can be adjusted up to three times by using tongs

or tweezers.

The crucible electrode has to protrude slightly from the

ceramic pan. Do not sharpen the electrode! Connect the

electrode with a wrench with the copper crucible support,

and tighten.

Melting electrode

The melting electrode in the upper melting chamber

has to be well sharpened (see section B 18). The position of

the melting electrode remains the same when casting with

alloys or titanium.

The space between both electrodes is 15 mm when

casting alloys. Small differences of ± 1 mm do not have

an influence on the casting.
