|The standard stainless steel cooking bowls (un-wok-like), with a paucity of tone-ballast.|
When I was angling to incorporate pseudo-cauldrons into resonant assemblies, the adage "beggars can't be choosers" manifested itself in the galling fact that dishes and bowls receptive to magnetism are very hard to find. If you walk into a shop, all the stainless steel bowls will be non-magnetic. This is frustrating, as many of the most resonant bowls will not be suitable for resonating via the electromagnetic field method (a non-contact method of resonating).
Looking in bins and trade waste containers can yield older steel bowls, where the steel was treated differently during manufacture, thus retaining its ferric virtue and allowing for EM resonation. Although, these are rare.

I recorded a short and unpolished study simply to display aspects of this chord. (Please excuse the unskilful pickup collisions)....
