  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  Glass 
  was  known  to  the  Egyptians  at  a  very  early  period  of  their 
  national  history,  at  least  B.C.  1500.  Various  articles  both 
  useful  and  ornamental  were  made  of  it  as  bottles,  vases,  etc  A 
  glass  bottle  with  the  name  of  Sargon  on  it  was  found  among  the 
  ruins  of  the  north-west  palace  of  Nimroud.  The  Hebrew  word 
  _zekukith_  (Job  28:17),  rendered  in  the  Authorized  Version 
  "crystal,"  is  rightly  rendered  in  the  Revised  Version  "glass." 
  This  is  the  only  allusion  to  glass  found  in  the  Old  Testament. 
  It  is  referred  to  in  the  New  Testament  in  Rev.  4:6;  15:2;  21:18, 
  21.  In  Job  37:18,  the  word  rendered  "looking-glass"  is  in  the 
  Revised  Version  properly  rendered  "mirror,"  formed,  i.e.,  of 
  some  metal.  (Comp.  Ex  38:8:  "looking-glasses"  are  brazen 
  mirrors,  R.V.).  A  mirror  is  referred  to  also  in  James  1:23.
