– Always place set invested rings in the burnout furnace with the opening facing downward, preferably
at a 45° angle.
– If several investments are carried out at once, the investment rings should be placed into the preheating
furnace in 20-minutes’ intervals.
– The investment rings must not touch each other. Permit air circulation.
– When divesting the object, make sure that you remove only excess investment material during preblasting
at 4 bar pressure. Be careful not to blast the ceramic object at this pressure.
Safety Warnings
– Do not open the burnout furnace during the first 30 minutes of preheating since the wax vapour
could ignite when exposed to air and cause a burn!
– Warning: The investment material contains quartz powder. Inhalation of dust should be avoided.
(Prolonged exposure to dust may cause lung damage and silicosis).
