Make your own ink!
For easy-to-make homemade ink, which is ideal to be used in scrap books or stamping, you would need the following materials: a plastic jar which contains a lid that could be tightly closed, laundry bluing (this could be purchased within the laundry soap section of your local grocery store), egg yolk, honey, gum Arabic, a candle.
When you want to make a blue-colored ink, the first step is to place laundry bluing in the plastic jar. After which, add a sufficient amount of water (the quantity depends on the intensity of the ink color you want to see). You now have blue ink that is ready to be used by you.
When you want to make a black-colored homemade ink, combine eight ounces of honey and egg yolk. After which, add gum Arabic, approximately a quarter of an ounce. Then, using a pan, hold it atop a lighted candle in order to produce a black slick at the pan’s bottom. Add in a bit of the honey mixture. Remember that prior to utilizing this mixture, make sure to add water. Then, place this in a jar and place it in storage with the lid closed tightly. Voila! You now have black ink.
In order to make your own homemade brown ink, use four tea bags and place them in ½ cup of water (preferably boiling). In order to make the solution a tad thicker, include cornstarch. You can now use this brown ink at your own leisure. Specifically, this could be utilized along with ink stampers.
However, when you want to challenge yourself, you can make the process of homemade-ink making quite difficult.
You can use iron gall ink – an ink mainly used during the 12th to 19th centuries in Europe. Why gall ink? Reportedly, this specific type of ink is easy to make and puts out a permanently striking black color. However, the ingredients for gall ink needs a quick trip not to your friendly neighborhood grocery store but the woods.
Essentially, you need to have ferrous sulfate, oak gall, water and logwood. Take note that oak galls are circular-shaped growths which appear when wasp species lay their eggs in the leaf of an oak bud. However, fear not if you see no galls around as you could easily substitute it with oak twigs and acorns (do note that these are excellent sources of tannic acid). Also, since the ink virtually has no color, you can add in logwood dye to create colored ink. This particular dye is created by boiling logwood in hot water. Meanwhile, gum Arabic allows the pigment to be suspended in the solution and incorporated in the ink thereby adding body and helping it flow.
When you have all the needed raw materials, crush the galls and boil it (as advised, you can similarly use oak materials). Do note that oak produces a foul smell. It is highly advisable to do this outside your home. Then, filter and combine ferrous sulfate to the mixture. After which, include the logwood dye. Voila! You can now bottle the ink and start writing with it. Make sure to feel proud because iron gall ink is the same one used to create the Torah scrolls and the compositions of classic composer Bach.
