Good Morning

The 1 step process is the norm but that is 2n and requires additional processing if you want purer silicon.  The QRR is intended  to get 4N nor better  in one step so it can be used directly. So step in the right direction as it proves the machine can make silicon but the purity results are what will confirm the viability.  Obviously you arent getting 4N on the first run.
