This is one of my "Mineral-Encaustic Art' (c) pieces that I created.  It also uses recycled glass that I pick up from other people's litering our parks & mountains along with Jaspers, Obsidian, and various Quartz pebbles from Colorado.  It is framed in a layered effect on cabinet grade wood.  The size is 2.5' x  3'(roughly).  This piece has won many awards here in Nebraska between County and State levels - Best in Class, Grand Champion, 1st (county) and 2nd (state - because another piece of mine took 1st place that same year)
