Got Ink?


Hello. Gents, Lads. I'm trying to make some ink. I did a little of research and found two recipes; and was wondering if the ingredients aren't hazardous/flammable/dangerous to handle nor banned to be shipped online.

The two recipes are:

Iron Gall Ink
---------------
11.7 g tannic acid
3.8 g gallic acid C6H2(OH)3COOH
15 g iron(II) sulfate
3 cm3 hydrochloric acid (used to prevent sediment forming)
1 g carbolic acid (phenol) C6H5OH (biocide)
3.5 g china-blue aniline dye (water-soluble)
1000 cm3 distilled water[10]
---------------
Stark's Ink
-------------
Twelve oz. nut-galls
8 oz. each, sulfate of indigo and copperas <i don't understand whats this<
A few cloves
4 or 6 oz. of gum Arabic
(for one Gallon of ink)
-------------



if you guys can help me out with some guidance, i would appreciate that.
feel free to share any recipe. Thanks.

The only really hazardous chemical is phenol. You should avoid exposure of your skin to the solid or concentrated solutions of this, it gives really nasty blisters if it is allowed to sit on your skin. Once it is diluted (such as in your recipe, at only 0.1%) then this is not really dangerous anymore.

If you can obtain these chemicals, then I would say that both inks can be made safely, as long as you use common sense and avoid exposure to skin and eyes of the concentrated chemicals. If by accident some of it is spilled on your skin, then you should not panic, just quickly rinse away with a lot of water.

Tannic and gallic acids are present in many food and drink products derived from plants, tea and coffee are brown due to plant tannins (of which the former belongs and the latter is derived via hydrolysis).

Iron(II) sulfate is used as an iron supplement and fortifying agent, shouldn't cause you any harm.

Hydrochloric acid (even concentrated) won't affect you for at least half a minute as it works through the dead skin layer, pain occurs quite a while before significant physical damage is done.

Phenol causes proteolysis at 5-7% concentration, responsible for chemical burns; lower than that it is a great antiseptic and was routinely used by Sir Joseph Lister for preventing post-surgical infections. https://www.drugbank.ca/drugs/DB03255
MSDS: http://www.sciencelab.com/msds.php?msdsId=9926463

China blue will liberate toxic gas when reacted with strong acids according to this MSDS: http://www.dunelm.com/infodocs/msds/fabric-dye-china-blue-50...

Dihydrogen monoxide shouldn't cause you any problems, you can bathe in it and expect to turn out unscathed. /s

Indigo dye is labelled as a skin and eye irritant (what isn't, though?) and is quite likely hazardous if ingested and/or inhaled. MSDS: http://www.sciencelab.com/msds.php?msdsId=9924357

- A side note about MSDSs is that they are designed for the industrial scale production and handling of chemicals, hence why they seem over the top. Basic lab safety is all you need for small scale production, and treat any unknown chemical as if it will kill you, melt your flesh, fill your lungs with fluid, etc. (that's my ethos anyway, just in case you do happen to acquire something which can). Keep safe and happy experimenting!
