Karen,

Back in the late 50s, I worked for a shop that had a contract to do the
machine
work on 3k aluminum castings that were the body for an oxygen regulator for
breathing oxygen for the USAF. After we finished, they went to the people
who assembled and tested them. We heard the castings were all porous.
We were ecstatic, as we thought we would get to do it over again. Alas, we
heard they treated them with waterglass and saved them. I once told Ken
Henderson that fact he was still alive proved that it worked. That's all I
know about the subject.
