Gouache is a beautiful, water-based artist paint, similar to acrylic or an opaque watercolor. It's completely intermixable with watercolors. Learn how to make your own natural gouache paint below!
Supplies:
- Earth & Mineral Pigments
- Gum Arabic Powder
- Natural Impasto Medium (limestone powder)
- Honey (for a vegan version, use glycerin)
- Optional: clove or thyme essential oil (mild preservatives)
Instructions:
Part 1: Creating the Gouache Base
Step 1: Mix 6 Tbsp. hot water with 3 Tbsp. Gum Arabic Powder - mix until dissolved

Step 2: Add 2 Tbsp. honey or glycerin to the water and gum arabic mixture and mix until dissolved. At this stage, if you choose to use a preservative, add two drops of clove or thyme essential oil to help preserve your gouache paint.

Part 2: Create the Pigment & Limestone Mixture
Step 3: Scoop 1 Tbsp of Earth & Mineral Pigment (we used Ultramarine Purple!) into a dish.

Step 5: Add 1 Tbsp of Natural Impasto Medium to the pigment and mix/ stir with a spoon or fork until evenly distributed.
Note: Play around with these proportions - some artists use 1 part pigment:1 part impasto medium and some use 6 parts pigment: 1 part impasto medium. It depends on the color and also how pigmented you want the paint.

Part 3: Create the Gouache Paint
Step 6: Mix one part gouache base with one part pigment and limestone mixture. For example, mix 1 tablespoon of base and 1 tablespoon of the pigment and limestone mixture. Adjust the ratio as needed; as all pigments absorb binder differently, you may need to experiment to achieve the desired paint texture.

Step 7: Paint away!

Storage: Store the gouache paint in a small airtight jar or aluminum tube. Refrigerate to prolong the paint's shelf life. You can also dry it in pans (like watercolor) and re-wet to reinvigorate it.
