A device of quartz glass for receiving or holding work pieces to be heated in a furnace, a region of the device projecting into the hot furnace zone having an arcuate part with a beginning of curvature and an end of curvature, which is enclosed by a vessel filled with an immersion liquid, heat radiation passed in the material of the device in a region located before the arcuate part due to total reflection being coupled out of the arcuate part and being coupled into the immersion liquid and a region of the device adjoining the arcuate part together with further device parts present at it being colder than the region located before the arcuate part.

A device of quartz glass for receiving and holding a workpiece proximate to a heated area, comprising: a first end for insertion into said heated area; a second end, distal from said first end, to which heat should be prevented from flowing; a heat absorbing portion disposed between said first and second ends, said heat absorbing portion including a curved portion joined to said first end for thermal transfer therethrough, a vessel disposed about said curved portion, said vessel including an immersion liquid which surrounds said heat absorbing portion, said heat being coupled by total internal reflection from said first part through said curved portion to said immersion liquid to thereby thermally insulate said second end; and means for attaching a workpiece to at least one of said second end and said heat absorbing portion.
