[papercreters] Re: using waterglass

Thanks you, Charmaine. Think I will experiment with 1 gallon.

So it probably won't be working its way into the mix of this fall's project but at least I'll know whether it's worth pursuing in the spring.

And... it may be cost prohibitive, depending upon how much needs to be used in the crete mix to achieve meaningful results.

Was hoping you had some simple solution for making it yourself. It didn't sound so simple when I read about it on Wikipedia and elsewhere. Sounds like one would need a special kiln and good knowledge of industrial chemistry in order to do so safely.

So I'm still looking for a good, lightweight, water-sealing coating for the current project. Don't have the big-paddle prickly pear cacti here or I'd love to use cactus juice. But I really don't see those until I get well south of Socorro in New Mexico. They are plentiful down around Deming. Can't justify the time and expense right now to make a 300 to 770-mile roundtrip to harvest a trailerful.
