Availability
Corning Fibergles plans to have our total
changed to Asbestos Free by January , 1973. this change over before then As

Naturally we will start
have an acceptable product on
explained to you we are already
making field tests on
our filter press lineaand are currently

ready in time for Bellows Creek
Therefore we will have this material
if our contractor is successful
If there are any further questions on this
