Hi! I made homemade walnut ink yesterday from green fruits from my backyard. I am happy with it... it writes well. I put some cloves in it for preservative, but I was wondering if anyone has tried freezing it.
Why would you want to freeze it?
I was worried about mold
I see.
Having boiled the ink for a while, it should be, at least in the beginning, mold free. Take care that your containers are equally clean before use.
Living in a mostly hot, humid environment (Atlanta, GA), I was plagued by mold constantly. Often you will see recommendations to use distilled water when diluting ink, which I did for years. Moldy ink all the time. A couple of years ago, I switched to using simple chlorinated tap water to dilute inks. No more mold. I have a one ounce container I've been using for over a year of McCaffery's Penman's Black that is open every day and which I top off almost daily from a four ounce bottle and occasionally dilute (to counter evaporation) with chlorinated water. No mold in over a year. Perhaps the chlorine is killing the mold or stopping it before it can get going. Something to try if you are diluting ink.
