* The determined continuous heating times correspond with our technical process experience with castings using

exclusively new materials and are provided as recommendations. The specified values may deviate depending on
the specific alloys, in particular when using non-BEGO alloys.
Note: The table on the following page is provided to record individually determined continuous heating times.

** A glassy-carbon insert may be used as an alternative to the ceramic insert.
