I found some ink cap mushrooms at spring meadow today!!
Did you know you can use the ink to write with?! Here's how....
Ink cap mushrooms, particularly species like Coprinopsis atramentaria (common ink cap) and Coprinellus micaceus (glistening ink cap), are known for their unique process of deliquescence, where their gills dissolve into a black, inky liquid. This "ink" can indeed be used for writing and drawing.
Here's how you could use it:
* Harvesting:
* Timing is Key: Look for mature ink cap mushrooms that are just beginning to deliquesce. You'll see the edges of their caps starting to turn black and drip. If they're too young, they won't have produced enough ink; if they're too old, much of the ink might have already dripped away or dried.
* Collection: Gently pick the mushrooms, preferably when they are still relatively intact but showing signs of "melting."
* Ink Extraction:
* Natural Deliquescence: Place the mushroom caps (gills down) on a non-absorbent surface, such as a ceramic plate or glass dish. As the spores mature, enzymes in the mushroom will break down the cap and gills, causing them to drip the black liquid. This process can take several hours to a day.
* Assisted Extraction (Optional): You can gently press or crush the disintegrate caps to encourage more ink to release, but be careful not to introduce too much mushroom flesh, which can make the ink clumpy. Some people will put the caps in a jar and let them sit for a day or two.
* Preparation for Writing:
* Filtering: The raw ink will likely contain mushroom bits and spores. To get a smoother writing consistency, filter the liquid through a fine mesh sieve, cheesecloth, or even a coffee filter. This will remove larger particles.
* Thickening (Optional): If the ink is too watery, you can gently reduce it over very low heat (do not boil, as this can degrade the pigment) to concentrate it. Alternatively, some people add a tiny amount of gum arabic (a natural binder, available at art supply stores) to improve flow and prevent smudging once dry. Start with a very small amount and add more gradually if needed.
* Preservation (Optional): Mushroom ink is organic and can spoil or grow mold. To preserve it, you can add a tiny drop of a natural preservative like clove oil, or a small amount of rubbing alcohol or vinegar. Store it in a sealed container in a cool, dark place or the refrigerator.
* Writing:
* Tools: The ink works well with dip pens, quill pens, or even fine brushes. It's generally not suitable for fountain pens due to its particulate nature and potential to clog.
* Paper: Experiment with different types of paper. Absorbent papers might cause the ink to bleed, while smoother papers might work better.
Important Considerations:
* Color: The ink is typically a rich black, but its exact shade and permanence can vary depending on the mushroom species, its age, and how it's prepared.
* Permanence: Mushroom ink is not as permanent or lightfast as commercial inks. It can fade over time, especially when exposed to light.
* Safety: While the ink itself is generally non-toxic, always be certain of your mushroom identification if you're harvesting them. Never consume wild mushrooms unless you are 100% certain of their edibility. This is for ink, not food!
* Smell: Fresh ink might have a slightly earthy or mushroomy smell, which usually dissipates as it dries.
Using ink cap mushrooms for ink is a fascinating natural craft that connects you to traditional methods of ink making!
