Making Liquid Gum Arabic

Making Gum Arabic

Resin binder used for tempera, watercolor and gouache; it stays water-soluble through the ages. Buy liquid gum in art stores or make your own from powdered gum. Making your own is far less expensive.

 You need:

  • Gum Arabic powder
  • Distilled water (only necessary if your faucet water is alkaline)
  • Small deep bowl
  • Small saucepan
  • Pipette
  • Whisk
  • Lidded container
  • Clove or other strong essential oil to help prevent odor and mold as liquid ages
  • Glycerin [optional]


  • Put 1 tsp gum Arabic powder into a jar with 1 cup of water
  • Stir well to remove lumps in the powder; a small whisk is handy
  • Place jar in a saucepan filled with hot but not boiling water
  • Keep saucepan over heat long enough to dissolve the powder
  • Gum Arabic slowly dissolves and looks like water with resin odor.
  • Add 1part gum Arabic liquid to 5 parts glycerin for smoother liquid [optional]
  • Let stand 2-4 hours, to overnight
  • To mix paint, use pipette to add 2 parts water to 1 part gum Arabic, then mix with dry pigment

Short-cut Method:

  • If in a hurry, do this:
  • Stir gum Arabic powder into 1 cup very hot but not boiling water
  • Keep stirring until the powder dissolves
  • It may be necessary to heat the powder / water mixture until powder dissolves
  • Rushing things can leave undissolved powder in the liquid


  • Well-capped, gum Arabic liquid keeps at room temperature for several days
  • To keep 6-8 months, add 1drop clove oil and refrigerate.
  • If gum thickens, add a few drops of distilled water

  1. I am interested I have a milling machine. A roller milleing machine can i used it to mille Arabic gum

    1. We’ve never milled gum Arabic before, so we don’t know what will happen. If you want to make a finer powder from the dry gum, it might work. But if you are adding liquid, it might create problems with the milling machine. We have not been able to find any more information. Sorry, but you have asked a completely unique question! — Bjo

  2. Hi! Can this recipe be used to make watercolour paints for dry storage in watercolour pans? It seems like it’s a very ‘liquid/watery’ solution compared to other recipes I used.

    Thank you! : )

    1. Yrs, it can be used to make waterrcolor paints for dry storage. Just pour the liquid into the pan & let it dry. This has been done for centuries.
