Cool. I've got a gallon of that I bought for a lampworking project.
I'll put it to use.
I got my gallon from
http://www.chemistrystore.com/search.cgi?keywords=sodium+silicate [$15
& another $15 to ship it to NY- but I couldn't find it locally in a
small size]
">My 2 cents hope is helpful, I am in Illinois cool and wet now, so I
am using ferrocement instead of papercrete here. "
Very helpful- thanks. I've been wondering if PC made sense for
our northern climes. Are you saying you use Ferro-cement 'this time
of year' -- or because we have 'this time of year' Ferrocement is a
better choice?
I'm having a hard time imagining PC lasting through 100 NY winters-
and have been wondering if it isn't just coincidence [and local style]
that most of the folks on this list are from the Southwest.

>> The term "kick" is used to describe set-up time. If we have found one flaw in F/C it is the length of cure time. I found by accident that latex paint has an effect on the cure time. Whilst doing a workshop at Lost Valley we thru some discarded paint in the tow mixer. As usual we did not use it all and I simply covered it for the next days class. Imagine my surprise to find a half full tow mixer solidified the next a.m.!! I have since been using latex to cure times more reasonable and to add some moisture resistence to the mix.
