Opaque vs Transparent

Opaque colors used straight have total hiding power and bright top tones.  Both opaque and transparent colors can be extended with encaustic medium to make them more transparent.

Layers of extended color can be laid one on top of another or separated by layers of straight medium to create unusual translucent effects (with no wait for drying time between layers). Glazing can be done by greatly extending a color with the medium.  There is no technical danger in adding large amounts of medium to a color as there is in adding large amounts of oil to oil paint.  The encaustic can also be made more fluid by adding medium or raising its temperature a little.

For variations of surface effects, different degrees of fusing can be employed.  Well fused paint will take a higher polish than paint that is not as thoroughly fused.
