Bon Chef5151 Stainless Steel Bowl Insert Fit Fondue Pot, 6-1/4" Diameter x 2-3/8" Height

Does this have a flat bottom? Can it stand on its own on a table?

is this oven safe?

Where is this made?

Is the insert supposed to fit snuggly into/onto a Bon Chef fondu pot? Mine slips and slides around, unevenly aligning with the rim of the pot.
