Trammer, 2013

The Trammer is an outdoors structure which is notably made of a working sieve. A beeswax wafer filled with gold glitters is placed at the top of the structure, in the gold panning. Canalized with the use of the panning put under some glass material, sunrays eventually make the wax melt. The six sieves of progressively thinner mail are to sort the glitters out and collect them. A basin is used for that, acquiring the wax once filtered out.
The Trammer can be freely reactivated by putting the wax at the top of the structure again, right in the panning, until gold pieces are no more.
It has to be noted that a complete cycle, depending on the sun and the season, may vary from a few hours to quite a few months.
