I got told that if you burn bread absolutely charcoal black in a toaster, it makes an effective filter to remove the undrinkable stuff from the methylated spirits. Leaving only the ethanol. Allowing you to get off your chops for cheap.

I'm no chemist but I suppose bread burned black might make a sort of carbon filter or something. I'm not sure that I would want to test that theory though!

Seems to me that if the goal is just to get drunk, there are less risky ways to do that for equally cheap money.

That's basically what is happening.

Apparently it happens in remote communities where there is no booze available (dry area) and by people who have nothing left except to drink.

Fully carbonised bread (aka. 'carbon foam') basically works like an activated charcoal filter and binds several chemical contaminants as they pass. Same as with respirator masks that have a layer of activated charcoal in them for this same purpose. The regular filtration membranes take out particles, the carbon binds gasses that can be harmful.

BTW.. A fully carbonised piece of bread works great too as a heat/flame shield if you need it in a pinch somewhere. It's brittle so needs a little care, but you can point a flame at it and it will take ages for the back to get hot. The 'fluffier' the original bread the better as the air pockets help the insulation.

Bye, Arno.

I used both alcohol and acetone based on what is closest to me unless removing oil or grease, in those cases I go for the acetone.
