Outline (or reservation), white ground and polychromy were techniques common to both Attic, and Corinthian pottery. Corinthian clay did not retain decoration: there was a tendency to flake and it did not produce a high gloss like the Athenian black slip. Three cultic vessels recently excavated in Corinth were highly polished and firing conditions were more controlled than for common Corinthian pottery. Whether the outline technique was developed independently in Athens or Corinth or was burrowed from each other cannot be determined, but the style did not become popular in Corinth where the undecorated put covered only with slip or banded in red and black was preferred. -- AATA
