It is a common question that people ask, if a certain chemical is OK to use for extraction or not, and also where to find such and such chemical. Instead of cluttering up the forum with hundreds of threads about it, those who have these question can post here (and threads made with such questions will be merged here).

But before asking such questions, here's a few important links you should THOROUGHLY read:

EDIT:
though the question stays interesting, they ask too high costs, so never mind.
I still would like to know what the expression "technical" means in term of purity.

Technical is the brand name. I made the same assumption you did recently and thought it meant something else:roll:

I'm not home in the chem world, but I thought there really was something out there like techical-grade. Not so? Perhaps there is a brand indeed named like that.
Remaining puzzled :?:

Hi all, first post here. Used to be very active on Shroomery but have been on hiatus for a while with life an all that jazz. Looking to spice my life up again. 😁

1. New to the UK so not familiar with brands and products. I've read B&Q, Boots, Wilkinsons for caustic soda. Any better than the next or higher purity? I'd like to get this right the first time and do a small scale variables test.

2. Also I'm assuming tap water is alright around here?

3. Ronsonol lighter fluid it is? anything cheaper/more cost effective? Wheres the best/cheapest place to get it?

4. Is the salt I keep reading about magnesium sulphate? The one that can enable a better pull? Or are we talking about table salt?

Thanks all in advance :thumb_up:

Any good in person places to get the ronsonol or swan cheap?

Also how do I find heptane on ebay? Tried and nothing seemed to show up.


Thanks again! 8)

Tesco supermarket is the cheapest ive seen ronsonol. £1.10 for 133ml iirc. For some weird reason my local tesco stopped selling it but i just searched google and tesco says they are still stocking it so i would try and find a tesco near you :)

Cheers guys.

Think I'm getting that heptane as per unit it seems pretty cheap. Free shipping on additional purchases. Probably going to get 6L as its not going to get cheaper or go bad any time soon :) 6L = £12 Could come in handy for other projects 😁

Also thanks again for the salt clarification. On the other side of the pond iodized salt is quite common.

I have some questions about the different types of naphtha found here where i live (not US).

Some says "Naphtha (petroleum), hydrogen treated, light"
Others "Naphtha (petroleum), hydrogen treated, heavy"

I have got me some naphtha of the "Light" type and it also says "gasoline of heptane type" and "Technical grade".
It evaporates without leaving any traces whatsoever.

Is the "Light" type the best one?
Are there uses for the "Heavy" type also?
