Chinese Drywall

After reading about the recent discovery about contaminated drywall from China, I became concerned about using drywall as a source of gypsum for mushroom cultivation. Might be something you'll want to consider. Getting gypsum from your local beer making supply house would be a better choice. http://online.wsj.com/article/SB123843935950270581.html

At some point, people have to boycott this stuff from china that is destroying our economy and lives. Use sheetrock brand drywall, and never shop at places like walmart. In fact, the last time I stepped a foot inside walmart was in 1982, so trust me when I say there's NOTHING that you need for mycology that you can't find elsewhere.
If you're an American citizen, you owe it to yourself, your future, and your country to find the Made in USA label and boycott toxic waste being shipped over here from china for no other purpose than to destroy the American economy, our jobs and our very way of life.
This applies to those of you in Europe, Canada, Australia, etc., as well. Don't let the Chinese do to your country what they've done to ours. Boycott the bastards. RR

Sorry to go slightly off topic, but I have loads of Plaster of Paris and am wondering about using it as a source for gypsum.
So am I correct in thinking that if I can get Plaster of Paris, add water, allow to dry, and grind up the hard Plaster, I will have gypsum?
PS. No Walmarts in my country, but screw em anyway.

What?
You want to get it wet, let it dry, get it solid, then grind it up? Am I missing something or is that the most contradictory plan ever?

Plaster of Paris is actually anhydrous gypsum, if I remember correctly. Gypsum that has been heated to remove moisture and powdered.
So actually, this would work as far as I recall. Of course, it's time and labor intensive and you might be better off finding another source of gypsum if possible.

Thanks, Ill try it anyway. I have loads of PoP and therefore no real need to try find Gypsum. Besides, the labour doesn't really bother me that much, and if I do it right, it should be really easy.

Sorry RR, I have loads of respect for you, but that is a lot of hating on a whole country that I'm not sure is entirely justified.
An enormous amount of labor outsourced abroad to countries in Southeast Asia originate from American companies, because domestic labor is too expensive with trade unions, benefits, and health care driving cost per hour to $70+. It's not China's fault that Walmart wants to buy stuff made over there for 10 cents an hour. There is a lot of trash there, but not everything is garbage. Plenty of companies pay more for good labor that creates good products. Frankly, I'd like to see what Americans and Germans produce if their workers were given the same incentives and working conditions.
But it's true, cheap labor in China is one reason things "aren't made like they're used to," but to take the stand that China is exporting to the US "for no other purpose than to destroy the American economy, our jobs and our very way of life" is a little extreme. It's no more their fault as the fault of the American public that's willing to compromise their standards of quality to save a few bucks.
So, I agree with your perspective that we should be buying American, but doing so out of blind patriotism isn't the answer. American companies need to start producing American-made products that justify their higher cost, which they don't always do. (That said, I love my AA PC.)
Anyway, I've taken the thread way off topic, so off of my soapbox I go.
