Being rich in harmful chemical solvents such as xylene, felt tip markers are not safe as they are known to leave people feeling sick after exposures to certain amounts. The purpose of this project is to create a new type of ink that will not have the same harmful effects as the inks used today.
Coniferous red cedar tree leaves were extracted of their valuable chlorophyll. A mass amount of these leaves end up being trimmed off every year and they have no apparent use. They are even known to be bad for compost due to their high acidity levels.
The chlorophyll ink consisted of an alcohol based solvent and was inserted into the wicking sponge of a marker. The results showed a high quality marker with traits similar to a permanent one that are sold in markets today.
As this experiment was a P.O.C (proof of concept), people can now take into consideration that this method truly does work and so therefore, the ways forward are abundant.
The future of plant based markers depends on the chemicals inside of leaves which include: chlorophyll, anthocyanin, tannin, carotenoid, and xanthophyll (which also provides different colours). Not only can these chemicals be found in the leaves that were used in the experiment, but it can also be found in other autumn leaves, corn stalks, and grass.
