Now if only I knew where to get powdered Prussian blue and shellac flakes.... Sounds like a Dave Gingery sort of thing.

We used what we had in the 'chemicals closet'. I imagine that isopropyl would work fine. In any event, I prefer my alcohol with the aftertaste derived from ageing in an oak barrels. Straight up doesn't hold much appeal.
Gingery, no, although you're not far off. Connelly makes reference to using shellac flakes with Prussian blue and alcohol. Truly there's nothing new under the sun.

No idea about Oz. In Spain we still have a few 'droguerias' -- drug stores (but not pharmacy/chemist's) that sell a strange, atavistic, mix of art supplies, household cleaning products, and chemical compounds. The powered Prussian blue was ~€20 for 100g.

Joe,
I think you just answered my riddle of why, "Metho" doesn't smell anything like my snoz remembers. :scratch:
Although it could be that Pyridine is no longer used as the denaturing component for OH&S reasons. Or both.
Either way the new stuff don't smell right. :lol:

I'd always believed that Oz 'metho' was ethanol with a dash of methanol as the bittering agent... Literally, spirits that had been methylated.. Amazing how things, and memories, change...

Update...
Some interesting reading later, and it used to be as I remember. But since the methyl bit was poisonous, and people drank it anyway, the methanol was replaced with water and various bittering agents.
So, now claimed as non-toxic.
Will_D:
Interesting thread this.
Any idea of what the red pigment is in Dykem Red (or Yellow)?
PekkaNF:
Here we are pampered with two choices of shops to buy pigmets: Arts suplly shops...got 100g and they said I shoudl gring it finer. Traditional pain's and recepies are coming back into fashion and anything "non artificial" (no matter how artificial it really is as long as name and pagaging looks old) is in fashion big time. Next village of few thousand inhabitants has a paint shop that sells shellak, pigments, color paste, oils, solvents....
Pigments of any color...I suspect blue and yellow/orange/red would contrast.
Now I only need stock up and find the freaking ethanol or methanol, which are pretty much unobnanium except in industrial, pharmaseutical, or food industry. Some sort of ethanol is in windshield washer liquid, that has either -20C or -40C rating, last one sounds closer, but is it good enough for this use?
