The Meisner Effect or Bust?

LK-99 is not created using a particularly complex process or using any exotic materials. Two relatively common lead compounds are combined in a furnace and then a copper compound is added under a vacuum. From precursor chemicals to the final result, the process takes around three days. The claimed successful replications out of China have produced samples no larger than a grain of sand. To create a viable sample, this luck has to occur within a continuous chain of atoms to create a superconductor large enough to test.
