Ceramic Roller Problems - Horizontal Tempering

We are running across a large scale problem with brown clumps accumulating on our fused silica rollers in our horizontal tempering furnace. We have cleaned out our SO2 manifold and even swapped tanks - any ideas on what else to try?
The brown clumps are accululating sparatically across the entire roller hearth in odd corkscrew patterns, with the largest accululation in the last zone. I have pictures for those interested in helping me solve this problem.

Double glazed units for Georgian sash windows

The Channel 4 programme Grand Designs recently featured the restoration of an old industrial building near Bath. The planning authority allowed the use of double glazed units that would fit into traditional Georgian windows. These units were only 10mm thick and were filled with a mixture of xenon and krypton. I am considering replacing the glass in my windows and would welcome advice on where to find such units. Are there a number of companies that manufacture them?
