I have a question for the sheet rock experts.
I noticed that all of the sheet rock I bought last month has a distinct orange/pink tinge when cut (anywhere in the sheet), while sheet rock bought last year and before is whitish. Also the new stuff seems much more crumbly.
It doesn’t seem to fit any of the warning signs of the tainted Chinese sheet rock (no grey tinge, no smell, and no blackening wires) but it has only been in the house for a couple weeks, so it may be too early to tell. It was also purchased in central MA, away from the real problem areas.
I hope I am just being paranoid, but I would rather not redo the whole room again next year if there is reason for concern.
Is this anything to be concerned about or am I getting worked up over nothing?
Thanks for helping out the new guy.

What manufacturer? Never seen tinted gyp; and we go through literaly tons of it. I am however on the west coast.
Citrus rock?

It is "USG Sheet Rock Brand". It looks like the old white sheets and the new orange ones are the same brand.
Going by the odds ....
USG is a firm that I'm not too fond of, but they do make their own product, and have exacting standards of their own. I would never fear that a USG product was inadequate or contaminated.
As for the rock 'feeling' different, I'm not surprised at all. USG has an extensive research program, and they are constantly ammending their product line.
That's in my mind now when I buy sheetrock. If it's made in America you should be able to trust it.I'd contact their customer service dept to ask if they've changed the
formula or something.I recently noticed that the green board you get now has what appears to
be the regular paper backing instead of the black tar paper backing.I'm thinking about calling to ask about that. Guess it's cheaper.I don't like using the mold resistant kind that has fiber glass backing.It itches like hell after you work with it.
That new Greenboard is supposed to be better. Apparently, they are now treating the gypsum and the paper with mold inhibitors. I'll let you know in a couple of years if this is true!
Another good reason to wear a mask when working with it.Thanks for the info
I would not hesitate to call them and ask about it. Mike

Up here in Washington I have also used GWB with that pink or orange tinge. WTF?View Image
I don't know, but most drywall is recycled these days. Maybe some pink fiberglass is getting in there? Mike

With all the controversy over drywall these days, and the sue-happy environment we have, I would not be at all surprised if USG has started adding color as a way to identify their product.
At the risk of sounding really silly, I've gotta ask:
is your knife blade a little rusty?

If you are that concerned, remove it and start over now.... drywall is cheap.
It might be hydrogen sulfide staining. "Sulfides can originate from many common sources, including automobile exhaust fumes and high sulfur coal-burning power plants. “Pink” sulfide staining occurs when moderate levels of sulfide acid fumes in the air react with calcium carbonate to produce calcium sulfide (which has a pink-red color)."
