NOTE:
E N
Possible adhering/bonding of sintering cover
and sintering bowl!
When using for the first time, the powder is still
very sinter-active and would bond the sintering
cover and sintering bowl together.
▷ Do not mix in powder.
The powder may not be mixed in until after the
first two sintering runs.
7.2 Sintering
▷ Place the Sintron remainder/test crown cen-
trally onto sprinkled on pearls.
NOTE:
Danger of breakage of sintering bowl/cover!
When the bed of pearls is not loosened up, the
pressure on the sintering bowl/cover increases.
▷ To loosen up the bed of pearls: Insert the sinter-
ing cover [3] and apply a few twisting motions
until the cover abuts the floor.

The retort weight ensures the optimal sin-
tering result in the Argovent 2.
▷ Because of the high weight: When using
the tongs, support the retort weight
manually or with additional tongs from
below until placed on the retort.
▷ Position the retort weight onto the protective-
gas retort.
