Abstract
Embodiments of the present invention relate to a furnace system for growing crystals. The furnace system comprises a crucible for growing a crystal and a furnace comprising a housing having an inner volume. The housing comprises a through hole connecting the inner volume with an environment of the housing. An insulation plug is movably insertable into the through hole for controlling a heat extraction out of the crucible by radiation, wherein the insulation plug is free of a force transmitting contact with the crucible.
