How to make natural ink from Sumac

A natural ink Sumac recipe for the in-between time of spring.

It is that time of year where the snow is melting and hints of green life are starting to appear, but plants that provide us with ink are in low supply. This is when the long-suffering Sumac can provide us with a pop of colour.

Sumac grows in abundance; the berries and leaves are high in tannins and they can be used for ink all year round. Tannins are a group of chemicals that are pale-yellow to light-brown that are found in plant cells, especially in leaves, bark and fruit. Tannins discourage fruit-eating animals from eating the fruit until the seeds are mature and ready for dispersal. As the fruit ripens, the tannin content lessens. The tannins in sumac berries and leaves help create durable, long lasting colours.
Sumac berries also store well. The berries can be harvested in the summer when they are ripe and then stored indefinitely in paper bags. Always remember to leave the area where you forage as untouched as possible and to leave ample berries behind, as Sumac serves primarily as a winter emergency food for wildlife.

A few notes about this recipe. Water or vinegar can be used as a base of this ink but I have used vinegar to help intensify the colour. Please refer to my previous blog post if you have questions about alum, gum arabic or how to preserve your ink https://melissamaryjenkins.com/2020/06/05/answering-your-questions-about-natural-inks/ .

Ingredients:

3 cups cleaning vinegar (vinegar intensifies the colour)

3 cups fresh sumac berries and leaves (use your hands to remove the berries from the stems)

2 tsp alum

1 tsp gum Arabic powder

1 clove

Materials: *keep these materials ONLY for making inks *

stainless steel or glass (these are nonreactive materials) pot, lid, bowl, jar, stirring spoon and fork

fine mesh strainer

cheese cloth (enough to line the strainer)

rubber gloves

glass jar with tight fitting lid

small funnel

Directions:

-simmer the berries in vinegar and alum, stirring as needed until you reach the desired colour (about ½ an hour) be sure to keep the

*ensure that you are in a well-ventilated area and keep a lid on the pot to avoid breathing in the fumes.

-turn off the heat and leave overnight (not necessary but may help form a darker color)

-line the strainer with cheesecloth and place over the bowl

-pour the berries and ink into the fine mesh strainer and allow the ink to drain

-using your rubber gloves, gather the cheese cloth around the berries and squeeze out any excess ink

-dispose of the strained sumac and wash out the cheesecloth

-place the filter in the lid of a glass jar and line the filter with the cheesecloth

-pour the ink into the filter (repeat if necessary to remove any little bits of plant matter)

-whisk in gum Arabic a little at a time with a fork until dissolved

*if it is not dissolving, heat the ink again but don’t bring to a boil*

-when cool, add in a clove

-make sure that there is no air space inside the bottle (to help prevent mold growth)

-secure the lid and refrigerate to help preserve

-shake before use

* the pink sumac ink dries to a brownish pink colour on watercolour paper and remains peachy/pink on natural fabrics/paper

NOTES

Alum acts a mordant

Gum Arabic thickens, helps with controlling ink flow, binds the ink to the paper and helps preserve

adding a Clove helps to prevents mold

How to Make Green Ink with Grass and Water

How to make green ink with two simple ingredients: grass and water.

I set out to write this blog post before the snow settles on the ground here in Canada. We did experience our first snowflakes of the year last night, so I finally felt “the push” to post this recipe. I first heard about transforming grass into ink when I watched an online Zoom lecture by Marjorie Morgan. Marjorie is a natural ink maker, artist, printmaker and environmentalist. I highly recommend watching this workshop if you are interested in learning more about Natural Inks. Making Ink with Natural Materials Zoom Lecture/Demonstration for Greenfield Community College on 9/23/20!

Making Ink with Natural Materials by Marjorie Morgan

Now let’s talk a bit about what makes grass green. To break it down simply, grass leaves collect energy from sunlight through photosynthesis. The photosynthesizing chlorophyll in the leaf gives grass its green color. The grass ink recipe that I will share with you today creates a vibrant green ink that is such a beautiful and simple way to begin your natural ink journey.

Ingredients and Materials:

fresh grass

water

a blender (I use a Magic Bullet that I keep for ink-making only)

a funnel and coffee filter or a panty hose sock or a piece of cheesecloth/fabric and an elastic

a glass jar with a lid

a spoon or fork

paper (try different types i.e. watercolour paper and/or natural paper)

brush and/or eye dropper

a rag

pencil/pen and label

clove (optional)

Instructions:

-Grab 2 handfuls of fresh grass.

-Put the grass in your blender and add a little bit of water.

-Turn your blender on and blend until you get a rich green liquid. If the grass is struggling to blend, you may need to stir it up and blend more or add a little bit more water (it will smell like a freshly mowed lawn).

-Cover a glass jar with a filter of your choice: a funnel and coffee filter, a panty hose sock or a piece of cheesecloth/fabric secured with an elastic.

-Pour the ink into the glass jar through the filter.

-Using a paint brush, your fingers or an eye dropper, experiment with your new green ink on paper. You may wish to spray water onto your paper and then add drops of the ink and watch the ink travel into and across the water.

-When you are finished painting with the ink, label the glass jar, put the lid on and refrigerate.

The ink makes a rich dark green (that darkens as it dries) and lasts surprisingly long. Keep out of direct sunlight to prolong the colour on paper. You may wish to add a clove to your jar to help preserve the ink.

DIY avocado ink without leaving home

an easy avocado ink recipe using baking soda and avocado

I thought that I would share my secret avocado ink recipe for all those who are looking to create with their little ones or to explore natural inks while “retreating” at home. I like to say that avocado ink is a “gateway” into the world of natural inks. You can create ink from both the shells and the stone (pip or pit). The beauty of avocado ink is that you can create a variety of colours from peach to blush pink to a deep brownish red. The range of colours can happen for a variety of reasons:

  • the age of the avocado pit
  • if the pits or skins have been frozen and at what stage of freshness the pits and skins were frozen
  • the age of the avocado skins (the older the avocado skins the deeper the red colour)
  • the ph level of your water
  • if you have completely cleaned off all of the flesh (bits of flesh can dull the colour)
  • if you cook the whole stone or chop it up (chopped stones release more colour) and
  • how long that you simmer the pits or skins

A few notes about avocado ink ingredients:

Soda ash otherwise known as sodium carbonate (the active ingredient in washing soda), is an important part of my recipe. It acts as an alkali mordant to help bring out a more vibrant colour. You should have this on hand, because all that you need to do to make your own is to heat baking soda in a 200°F oven for an hour. When using soda ash to make inks, it is important that you wear gloves, turn on your kitchen vent fan (or open a window), and cover the cooking ink to avoid breathing in the fumes.

You may not have distilled water on hand, but you can still experiment with tap water, and then when you are able to find distilled water, you can compare colour outcomes.

Gum Arabic thickens, helps with controlling ink flow, binds the ink to the paper and helps preserve. Gum Arabic is sometimes called acacia gum or acacia powder and it is made from the natural hardened sap of two types of wild Acacia trees. You probably won’t have gum Arabic powder lying around, but if you are a watercolour artist, you may have a bottle of liquid gum Arabic. Either way, you don’t need to have gum Arabic to paint with avocado ink and you can just skip that part of the recipe. Also, there is no absolute rule for exactly how much gum Arabic to add to ink. You can test different amounts with test strips to figure out what amount works for you.

If you don’t have 99.9% Isopropyl Alcohol, you can also use different purity levels (ie. 60%) or preserve with a clove, wintergreen oil or thyme oil.

Avocado Ink Recipe

*if you wish to make Avocado Skins/Shells Ink, simply substitute 1 cup of cleaned avocado skins in place of the stones

Ingredients:

1 cup of distilled water

2 large fresh avocado stones, cleaned and chopped (the more pits that you add, the darker the ink)

1 tsp soda ash

1/2 tsp gum Arabic

8-10 drops of 99.9% Isopropyl Alcohol

Materials: *keep these materials for making inks ONLY *

stainless steel or glass pot (nonreactive materials) with lid, bowl, jar, stirring spoon, fork and sharp knife

fine mesh strainer

coffee filter and small funnel OR panty hose sock OR cheese cloth and elastic band (you can wash and reuse)

dropper and ink bottle (or any glass jar with a lid)

Directions:

  1. Bring the chopped avocado stones, water and soda ash to a low boil, then reduce the heat to a simmer. The chopped avocado pits will begin to turn the water pink and then a deep maroon. This should take anywhere between 20-40 minutes to see the colour change.
  2. When the desired colour is reached, turn off the heat (*take care not to “cook” the pits).
  3. Soak off the heat for an hour or as long as desired (I usually leave overnight).
  4. Strain the pits into a bowl with a fine mesh strainer.
  5. Strain the ink again into a jar using a coffee filter and a small funnel or to create less waste, stretch a panty hose sock over the jar or use a piece of cheese cloth and elastic band. This is a slow process and you will be tempted to squeeze the filter. Resist the temptation.
  6. To add in the powdered gum Arabic, heat up the ink again but don’t bring to a boil (you can use a microwave). Whisk the powder into the heated ink a little at a time with a fork until dissolved. I have also used a blender to quickly mix in the powder.
  7. When the ink has cooled, add 8-10 drops of alcohol per a 1-ounce bottle of ink to help preserve the ink.  If you don’t have alcohol on hand, you can also preserve with a clove, wintergreen oil or thyme oil.
  8. Make sure that there is no air space inside the bottle (to help prevent mold growth) but if you don’t have a small bottle on hand the ink will be just fine.
  9. Secure the lid and refrigerate to help preserve.
  10. Shake before use

A few final tips:

  • It can be helpful to make ink samples during the slow process of creating inks. I use scrap pieces of watercolour paper, but just use whatever paper that you have available. Be sure to write down the time and other details (I have learned the hard way by thinking that I will remember).
  • Avocado ink lasts a long time even when it is not refrigerated. In fact, I love how thick it can get when left in a heated room. If mold does appear, simply scoop it off.
  • Avocado ink is also very lightfast. You can experiment with fading by leaving your samples in a sunny window.
