Quartz repairs Large and Small

We have seen a wide variety of work coming through our Glass blowing department in recent weeks. They have ranged from tiny small crucibles used in Assay Offices through to very large diameter jars originating from a research Lab.

An order to produce these small thimbles came in as the design required modification as the small lugs that hold the crucibles in the basket were snapping off.
The previous maker had joined but not welded the lugs in position. Its possible in this photo to see the differences between a joined and welded lug. The thimble on the left-hand side has a much larger area attached to the thimble body. The scale in the background gives an idea of the small size of these parts, the major scale is only 1cm.
