GLASS-MAKING  MATERIALS. 
GLASS-SAND   INDUSTRY   OF   INDIANA,  KEN- 
TUCKY. AND  OHIO. 
By  Ernest   F.  Burchard. 
LOCAL  GLASS-MAKING    INDUSTRY. 
Of  the  States  manufacturing  glass,  Indiana  and  Ohio  at  present 
occupy,  respectively,  second  and  third  rank.  The  total  value  of  their 
glass  products  amounted  in  1905  to  $23,733,137,  which  is  nearly  one- 
third  of  the  total  value  of  the  glass  made  in  the  United  States.  As 
the  glass  industry  is  largely  dependent  for  its  raw  materials  on  the 
mineral  deposits  sand  and  limestone,  the  investigation  of  these  mate- 
rials for  glass  making,  begun  in  1905  in  the  Mississippi  Valley,  was 
resumed  in  December,  1906,  in  the  Ohio  Valley.  It  is  of  interest  to 
note  the  sources  of  these  materials,  to  compare  their  costs  with  that 
of  other  materials  and  with  that  of  the  finished  product,  and  to  con- 
sider whether  any  economies  can  be  effected  in  their  production. 
The  following  table  shows  the  principal  materials  used  in  the  manu- 
facture of  glass,  their  quantity  and  cost,  and  the  character  and  value 
of  the  products  in  Indiana  and  Ohio  for  1905.°
