Besides sandblasting, how can I remove devit?

A glass tile with devitrification, covered with a thin layer of clear powder, then refired for a clean finish.

If your glass is flat, you can sift a very thin layer of Clear powder (about 2 grains thick) over the entire piece and fire it to 1425°F (774°C) - 1450°F (788°C) for about ten minutes, depending on your kiln.  This should remove the visible presence of devitrification.  Please note: This method only works if you don't intend to fire the piece again, as refiring could restart the crystallization.
