Guar Gum & Locust Bean Gum

I use both gums in my 'milk paint' formulations along with casein ( in the whole milk powder).  I am focusing on the locust bean gum becuase it forms a stable sol ( colloid) and I hope such derived paints will be stable for days/ weeks or months? Time will tell......

This (above) is Gum Tragacanth which can be used to make soft and hard pastels.
