Chartreuse a Clark made its debut at the 2011 International Encaustic Conference where it sold out as "Clark-treuse," named for David A. Clark.

It is a vibrant yellow-green, not for the faint of heart.

Like all Paint Sticks, this is heavily pigmented, which works especially well on monotypes.

To use as brushable encaustic paint, simply melt some of the Paint Stick with at least two to three times as much encaustic medium.
