The grate is suitable for firing silver clay on the gas stove. Place the grid on the pit so that the fire can heat the grid. Where the fire hits the grid, a glowing ring is created. Place your jewelry on the hottest part of the grid. The protective cage puts you over the piece of jewelry so that you are protected when the jewel is allowed to snap.
Also handy for drying the clay. You place the jewelery on this drying grid and then blow dry the jewelery. The grid can also be placed on a hot plate.
Note: that your jewelry is well dry because it could be the broken if not.
