Ok, so now you will have a Jar containing your 50/50 Dymark Raven Oil Mix. (Thinned with acetone.)
And a Jar of your random ink "bases". (For mine I used I splash of Corio, splash of Blue Illidel, Splash of Garvey and some Bleed through Concentrate, and some of the Purple Fiebings (Leather Dye.) and some of the Dykem Blue.
(No real method to this, I just tipped some this, some of that, into the jar, untill Id used everything I have....

)
Take your empty marker.
Add about 1/4 of the Dymark/Raven Oil mix.
Add about 1/4 of the Molotow Mix you've previously made. (if you have it, if you dont, dont worry.)
Top up rest of the marker (to just under where the thread starts, or less) with your "ink base" mix.
Add to this a heaped teaspoon of Gentian Violet, and if you want, another heaped teaspoon of Methylene Blue.
Watch your consistencies, as this has the potential to become extremely watery and "leaky".
Take into consideration how much of your "added inks" already contain plenty of xylene/alcohol/acetone whatever....)
Lift a few drops of Xylene using the maccas straw, and add those.
Add approx half a teaspoon of RP7 (or WD40, or fish oil....)
