Metol?
    #5715660 - 06/05/06 04:04 PM (17 years, 7 months ago)

"There are, of course, certain chemical applications used to speed up the bluing reaction which occurs in psilocybin mushrooms. One method involves "metol", a chemical used in photographic developing. "Metol" can be legally purchased from any camera and photographic supply outlet. Mix 1 part Metol with 20 parts water. Place the stem of the suspected mushroom in a "metol" solution and wait for approximately 1/2 hour. If the solution turns blue, you have actually collected a mushroom containing psilocybin."

http://www.mushroomjohn.com/guidetext7.htm

I have read conflicting information on the application of metol. Some say that it will simply spped up and enhance the natural blueing ON the mushroom rather than turn the solution itself blue, and then it is also cautioned that psilocybin is not exclusively effected by metol, but that any non-active blueing properties of the mushroom in question will react with the metol solution.

Any thoughts???

now don't get me wrong... But it sounds like a bunch of work and cash.

I think its time for you to get a grow on :wink: I will send you a nice dark spoor from them Texas Cubes and you wont need a chemical to tell you what you have :wink:

First, metol will, as you mentioned, speed up and enhance the natural bluing of the mushroom. The usual method is to apply a drop of solution to the mushroom and see what happens.

The biggest problem with metol is that it's poisonous. If you test a mushroom by putting a drop of metol on it then that mushroom is now poison and should not be eaten. The warnings on metol say that you shouldn't even allow it to come in contact with your skin.

It's not really worth the effort. The mushrooms that you want to check for bluing will turn visibly blue without it. Carrying it around means you have to take measures for handling a nasty hazardous material.

Here's a link to a material safety data sheet on metol. The biggest problem with it is that repeated exposure to small amounts can lead to serious health problems. Another thing is that it's extremely nasty to aquatic environments, so you need to find something to do with it other than dumping it down the drain.

Happy mushrooming!

Thanks toximan, I assumed that you would only wish to use metol if you had a lot of the same mushroom and were willing to sacrifice one. But yeah, that sounds rather questionable. erm, the adverse health effects anyway.

Good stuff, thanks everyone.

The use of chemicals as an indicator for identifying mushrooms can be very handy and a fun part of this hobby. I have been wanting to try Metol just out of curiosity. Metol isn’t necessarily going to be very efficient for the purpose of obtaining ids with Psilocybe but it would make for fun experimentation, especially with samples from various collections of known species.
Just this morning I put a tiny tissue sample of Rameria in 10% FeSO4 just for the fun of watching the reaction. Lets face it… we are all nerds and nerds dig on this kind of stuff.

You're right about the chemical reagents. I regularly use FeSO4, KOH, and Iodine for chemical testing.

Unfortunately, the Feds have pretty much decided that chemistry should not be a hobby in this country. It's getting tough to obtain chemical reagents, even really harmless ones. Gotta keep them terrorists from makin' bombs or meth, ya know.

Happy mushrooming!

No wonder our generation is flunking science!!!    :mad2:

Our government wants to control everything, and they are inhibiting our progression in science!  Trivial issues like whether stem cell research is ethical or not- retards!!!  I think our finding new cures and life saving medicine is a little more important than the fate of a few genetically engineered ambiguous cells!

so i bought some metol in seattle it was 4.95 i wanted to test some pretty interesting shrooms i found in some woodchips in my back yard there were two kinds growing there. the solution turned redish so i obviosly didn't eat them. but has anyone actually have any experiance with metol? the only thing i can find is mushrooms johns stuff and a new book that may suggest metol is a myth.

That metol info caem for Dr. Scott Chilton of the U of W.

It was applicable 30-years-ago when I wrote my book. However, it is not really necessary to use metol to know if you have a psilocybian mushrom sinc ethey can alreaddy be blue in their natural wild and/or man-made habitats.

We have showed bluing Psilocybes already naturally blue or blue green from oxidation.

When I return from Asia the metol part of the text will be removed from the book. For a new press run.

Same here in the UK. I have NaOH, KOH and NH3 but the FeSO4 is proving to be a problem.

Met a guy on a foray that works at the local University who should be able to help me out with some goodies though hopefully  :smile:

I just took some pics today that I thought would be relevant here, unfortunately, I'm having problems uploading them.
At any rate, I took pics of a cube and how fast it turned blue. When I saw this thread, I was thinking, by the time you could get things ready, you'd be sticking a blue stem into the solution, lol.
But then, something like this could possibly prove useful in a species such as Pan. subb., but this is a weak halucinogenic. On the other hand, P. semilancita don't bruise, do they?, yet are a strong halucinogenic species. So :shrug:

YEss Louise Louise, Liberty caps do have bluing in some. Especially if pinched and placed to dry under a halyte or a neon lamp. I am going to post a bluing in thread for some species to show bluing naturally already there before being picked.

inthe meantime, here is a shot of some copes form Thailand as I found them in the ground.

Newbie here-I purchased some metol and used it on some mushrooms i found today in a pine forest in the MA area.  I have about three or four of them that turned deep purple.  I always have trouble making spore prints though, any advice?  Are there any mushrooms that will turn purple with metol that are poisonous?

Also, in regards to:  ToxicMan's post:
"The biggest problem with metol is that it's poisonous. If you test a mushroom by putting a drop of metol on it then that mushroom is now poison and should not be eaten.
Thanks again."

I would do this experiment differently, instead just cutting off a piece of the stem to submerse in the metol.  I used an ice cube tray, and placed the rest of the mushroom next to the tray, so that i knew which species turned blue.

Also, I am curious about the extraction method I read on Erowid using methanol but its really hard for me to comprehend, does any one know of a picture tutorial? Here's the link: (http://www.erowid.org/plants/mushrooms/mushrooms_cultivation20.shtml)

EXTRACTION

Crumble and pulverize the dried mycelial material (does that mean the whole mushroom?) and combine each 100 mg
of this material with 10 ml of methanol. Place the flask in a hot water
bath for four hours. Filter the liquids with suction through a filter paper
in a buchner funnel with Celite to prevent clogging. (Im confused-Is there a photo/video tutorial on how to do this?) Collect and save the
filtrate liquids.  Heat the slurry (the mush in the filter paper) two more times in methanol as before, filter, and accumulate the liquids of the three extractions. To be certain that all of the alkaloids have been extracted do
a small extraction with a portion of the used slurry and test with Keller's
reagent (glacial acetic acid, ferrous chloride, and concentrated sulfuric
acid). If there is a violet indication, alkaloids are still present and
further extraction is in order.

In an open beaker evaporate the liquids to total dryness with a hot water
bath or by applying a hair dryer. Be certain that all traces of methanol
have been removed.  The remaining residue should contain 25-50 percent
psilocybin/psilocin mixture. Greater purification can be achieved, but would
require other solvents and chromatography equipment and is hardly necessary.

Each 100 grams of dried mycelium should yield about 2 grams of extracted
material. This should contain at least 500 mg of psilocybin/psilocin mixed
or about fifty 10 mg doses. Theoretically psilocin should have the same
effect upon the user as psilocybin. The only difference between the two is
that the later has a phosphate bond which disappears immediately after
assimilation in the body. In other words, in the body psilocybin turns into
psilocin.  Psilocybin is a fairly stable compound, but psilocin is very
susceptible to oxidization. It is best to keep the extracted material in a
dry air tight container under refrigeration. A sack of silica-gel can be
placed in the container to capture any moisture that may enter.

There are no mushrooms that I know of that will turn purple with Metol and are poisonous.

I can't help you with the extraction procedure.  There are other forums for that.

Smoobie, this thread was over two years old when you posted.  I know you saw the warning about making sure it was really important before replying.  Normally we advise against replying to old threads.  Don't do that, please.

Welcome to the Shroomery, the Internet's online psychoactive mushroom encyclopedia.  :smile:
