Wheat paste glue 1 to 1** with

  • ​ gypsum (terra alba - raw gypsum - not plaster of Paris)

Gum Arabic:

Dissolve in hot water before using.  This is a recipe I found on the internet.
“Ingredients. The ratio is 1 part gum to 2 parts water. Boil water (or use distilled water) and allow to cool to about 140° F (60° C) and then add the powdered gum, stirring to make sure there are no lumps. Continue warming the mixture at that temperature and stirring to dissolve the gum arabic completely.

Watercolor binder:

  • 1 Tbsp gum Arabic (liquid as from above
  • 1 tsp glycerine
  • 1 tsp honey
  • 1 drop clove oil (preservative)

Watercolor paint:


  • 1 1/2 Tbsp pigment
  • 2/3 tsp wheat starch (filler to make a smooth texture)
  • ​1/2 tsp kaolin clay
  • 1 tsp watercolor binder (add more binder as needed to make a good paste mix with the pigment)

*I have been reading up on wall board mud and plaster.  10% Talc added to the mix in mud reduces cracking.  I think I might try talc in my next primer recipe.
