Opaquer firing
(powder opaquer)
Remove the amount of powder opaquer required for the covering layer from the jar and mix it together with the
remaining, dried up “wash opaquer” on the mixing pad. Then, mix the powder opaquer with the Powder Opaquer Liquid
until it has reached the desired consistency.
Apply the second opaquer layer evenly and in such a way that the metal framework is entirely covered with opaquer. After
firing according to the stipulated firing parameters, the IPS InLine System Powder Opaquer should show a covering, silky-
mat shiny surface. After the opaquer firing, the conditioned surfaces of the alloy framework should be entirely covered
with opaquer.

tip:
A glass or ceramic instrument is optimally suitable to apply the IPS InLine Powder Opaquer for the opaquer firing.
Naturally, a brush can also be used to apply IPS InLine Powder Opaquer.
The IPS InLine System Powder Opaquer and Powder
Opaquer Liquid are ideally suitable for the application
with conventional spray-on techniques. Mix the powder
opaquer to a thin consistency, depending on the spray-
on system used. Observe the instructions of the
manufacturer of the spray-on systems.
Important
• Use distilled water to rewet the mixed or the already applied powder opaquer.
• The firing tray with the opaquerized metal framework should only be placed in the firing chamber and
removed from it once the furnace head is completely open and the beeper has sounded.
