Columbus Hollow Ware No. 12 Skillet
The No. 12 is the largest skillet Columbus Hollow Ware ever produced — and with its documentation, the SSC five-piece matched set is complete. It also delivers the final data point in the "S" mark investigation that began when the No. 8 was first photographed: present on No. 8, absent on No. 9, present on No. 10, absent on No. 11, present on No. 12. Even sizes carry it. Odd sizes don't. That pattern — confirmed across five consecutive pieces from a single provenance — is now in the published collector record for the first time
Columbus Hollow Ware No. 10 Skillet
The No. 10 is the pivot piece of the SSC Columbus Hollow Ware set — where the domestic cooking story gives way to large-scale provisioning, and where the "S" mark research takes its most significant turn. Present on the No. 8, absent on the No. 9, and confirmed again here on the No. 10, the subsidiary mark is clearly not a batch code or a uniform production identifier. It follows a size-selective pattern that only a five-piece matched set from a single provenance could reveal — and SSC is now on record with the comparative documentation to prove it.
