Welcome to the Nexus!
To make sure you get the best of this resource, check the
WIKI,
FAQ, and
Attitude pages. Most questions have been asked dozens of times before and people are encouraged to do as much of their own research as they can prior to embarking on the practical side of the journey of discovery.
Sometimes the forum search engine doesn't work as well as one might hope so it can be more productive to use an online search engine with a site specific search by typing in the following: "site:
dmt-nexus.me/forum [your search term, e.g. sodium carbonate]" (Without the quotes! And the search term doesn't need the square brackets, of course.)
Anyhow - it looks like normal caustic soda. Like any other brand of caustic soda it's dangerous if handled carelessly. It's "safe" to use if you follow safety procedures. Wear skin and eye protection - gloves and goggles. Add caustic soda to water, not the other way round. Avoid contact with aluminium. Use borosilicate glass where possible.
It's sold as a drain cleaner, if you're not "chemistry savvy" to the extent that you have to ask this type of question why do you think you'll be ok attempting to extract DMT? (Actually, it's no more difficult than baking a cake. Making a decent soufflé is harder. I seem to be feeling a little cranky this evening
)
By the way, there's a large, budget household store in the UK (W....) which sells caustic soda off-the-shelf - or at least it did a year or so ago, which is the last time I looked. I don't know what else you're ordering online for your project but I'd suggest this one might better be bought OTC. Things may have changed but it's still worth a look.
βThere is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
β Jacques Bergier, quoting Fulcanelli
