Can you recommend a supplier of fused quartz?

Using fused quartz as a surrogate for sand.  Difficulty achieving transparency.  Looking closely at the fused quartz grains, trapped air bubbles are visible and a likely problem (photo attached).

Looking for a new supplier.

Attached Sample Photo Info:

Pore fluid of Paraffin Oil and Mineral Oil (1.00:1.75) with RI of 1.4586 at 20 C. 

Varied temperature +/- 3 degrees with no improvement in transparency. 

Varied grain size of sample.  The passing #20 was LESS transparent than the sample passing #50 (the finer the sample, the clearer)

Fuse quartz is pulvated into the fluid; virtually no air trapped in the fluid of the sample (photo attached).
