Using RIT-dyed burlap - sketchy?
    #5373341 - 03/07/06 04:50 AM (17 years, 11 months ago)

I got ahold of a bunch of free burlap that I'd like to put to mycological uses. However, I'm told it was dyed using RIT dye. The only place I could find a list of ingredients for RIT was here:

http://www.walgreens.com/store/product.jsp?CATID=100755&navAction=jump&navCount=1&id=prod3805#

but they only list " Salt Sodium Chloride , Anionic Surfactants , Nonionic Surfactant", which is disconcertingly vague. Can't find an MSDS either. Anybody know what's really in this stuff? Heavy metals? Do you think it would be safe to use as bags/covers for outdoor cultivation (oyster)?

Thanks in advance.

But that doesn't really help, does it?

How many ya got? If it's just a couple, just use em for something else. don't take risks with your health, mate. I've run into burlap sacks in almost every city i've lived in, and i haven't ever used one for anything yet... If you live on the west coast, try Cafe Roma. They sell em for a buck. A friend here in new orleans has a hookup on the free from a coffee roaster, who is also a hookup on chaff. Check that out....

Thanks... I actually eventually found a more complete MSDS posted on their website (http://www.ritdye.com/msds.asp) - don't know why I missed it the first few tries...

The probably relevant sections include:
"Some components of these products have produced both positive and negative findings in in vitro mutagenicity assays. None of the components are classified as potential or demonstrated human carcinogens by IARC, NTP, or OSHA."
- and -
"These products contain no chemicals subject to the reporting requirements of Section 313 of the Emergency Planning and Community Right-To-Know Act"

I have probably several hundred yards of this dyed burlap - basically, as much as could be stuffed into a car. I've been using it for anything I could think of for months now - curtains, doormats, mulch - and there's still tons left. And since Stamets waxes so enthusiastic about burlap in Mycelium Running, and I have so freaking much of it... The quotes above suggest that it's probably pretty legit to use (at least in comparison to, say... aluminum trays), but I'll roll the idea around for a while longer before committing to anything.

It's great for outdoor grows. You can make a straw log using burlap instead of plastic. My indoor projects all fell to trich before harvest however.
