A stable homogenous emulsion of gilsonite arid lignosulphonates is disclosed. The lignosulphonates emulsify the gilsonite to produce a stable emulsion that retains an homogenous liquid character (without layer) during prolonged storage as a base stock composition. The emulsion is compatible with a broad variety of liquids, such as printing ink, wood stains, asphalts, and can be incorporated into such compositions without causing layering of the liquid. Homogeneity and compatibility of the emulsion can be further enhanced by adding an acrylic polymer emulsion to the gilsonite- lignosulphonate mixture.
