This etchable glass is used as cladding glass in fiberoptic bundles and as core glass in capillary arrays.  It is easily etched in low concentrations of acid and leaves no residue.

This etchable glass is ideal for producing virtually any cross-section geometry as well as and as multiple bores in rods and tubing.  It can be etched in low concentrations of acid and leaves no residue.
