Gotländsk Kalkstenshuggning
The Gotlandic limestone carving tradition — the working of the specific Gotlandic limestone (kalksten) whose particular fine-grained, slightly sandy texture made it the preferred material for medieval Swedish memorial stones (picture stones), runestones, and the extraordinary sculpted medieval churches of Gotland. The Gotlandic stenhuggare reads the correct limestone surface quality for carving through the same acoustic hammer test as the Hallstatt salt (CRAFT-1424) but calibrated to Gotlandic kalksten — tapping the stone surface and reading the specific ring that indicates solid, uniform limestone versus the duller response of a surface with hidden bedding plane weaknesses.
