In order to burn a project on the playa and comply with our Leaving No Trace principle, a “burn platform” consisting of decomposed granite (crushed granite gravel) or “DG” is required to separate the burning consumables from contact with the playa surface.
The DG burn platform extends a few feet beyond the footprint of the art piece at a depth of three (3) inches. The following formulas can help you determine the approximate amount of material and its estimated cost:
Rectangular Prism: V = w l h
- In order to determine the volume of a rectangular DG pad, multiply the width by the length and then multiply by a height (thickness) of .25 (3 inches). The result is the volume of the pad in cubic feet.
- Multiply the volume in cubic feet by .037 to convert to cubic yards.
- To find the price for amount of DG in cubic yards, round this number to the nearest whole number and multiply by $50.
Cylinder: V = π r² h
- In order to determine the volume of a round DG pad, multiply the squared radius of the circle (distance from the center of the circle to the edge) against itself, multiply this result by Pi (π = 3.1415) and then multiply by a height (thickness) of .25 (3 inches). The result is the volume of the pad in cubic feet.
