Vacuum wand issues

[Ted Berg]

Hello all,
      As  some of you might be aware we have recently had numerous 
issues with the vacuum wands on the furnaces   I have contacted the 
vendor of our vacuum wands and it looks like the bonder they use to 
attach the quartz to the metal is breaking down(melting ) as the wands 
are used. They are not sure if it is a shelf life issue or just a bad 
batch of the adhesive. They will repair our bad wands and have suggested 
an alternative. Even though the quartz is rated to 1400 degrees C the 
adhesive obviously is not.. Thank you for your patience. ted
