Very nice video. Thanks for taking the time to make this.

I'd love to see what other items can be used to make ink or dyes. 🙂 Great video

That was cool! Now to find out if we have oak gall wasps in Australia.

There are many kinds of oak galls, as there are many varieties of gall wasps and they have sometimes two sexual cycles (each one creates a different gall), only one type is called "apple" gall and there are also currant galls, marble galls, knopper galls, artichoke galls, silk button galls… The recommended galls for ink making were Aleppo galls, traditionally brought from Turkey (due to them having a higher level of tannin), but in the UK we can use marble galls. Iron gall ink is the most durable and resistant ink, but it's a nightmare for conservators, due to it's acid content and many historical documents have suffered the corrosion.

There are lots of oak trees on the farm where I grew up. In over 60 years, I only remember one tree ever having galls. Now that I know what they are I'll pay better attention. There might be more. Thanks for the video.

what a shame this episode is introduced by a couple of blokes who appear to not take the subject seriously. Horrible attitude and affected presentation.

I discovered this same property when I cleaned some carbon steel knives in a solution of very strong tea. Tannic acid is present in both tea and in oak trees! My knives, whilst clean and rust free were now completely black, although fortunately it did come off with some fresh water and a rag!

I thank you for the knowledge you've shared

They also needed to add a binding agent or something to thicken the ink.

Correct, check out clau's comment, it contains more in depth and accurate information than shared in the video.
