Help identifying glass pattern
This is a 'Glue Chipped' glass rather than a pattern.  Each pane of glue chipped glass is effectively unique due to the process.  First the glass surface is sandblasted.  Then glue is applied, which adheres to the sandblasted surface.  When the glue is removed it pulls away some of the glass surface leaving a uniquely 'chipped' finish.  Double chipped glass undergoes the procedure twice but requires a thicker glass because chipping will obviously weaken the strength.
Glue Chipping was often used to create signage for shops and bars by using a pattern stencil during sandblasting.  Geometric designs were also created this way.
