Our Xeno Glassworks OPTICAL glass bracelets, hand crafted of Pyrex glass, have mass; the borosilicate glass becomes a lens that magnifies light, color and pattern.  Not only do our OPTICALS take more working time than do our Originals or Specials, they require more fire and a longer annealing in the kiln to coalesce all that's gone into them. Variations of Opticals may include bas relief and under textures, the kinetic of refracted light through amorphic surface details, the contrast between frosted and satin violet, or that of dichroic color.

OPTICALS are 12mm up to 19mm.
