Here's a chunky vase that confused me a little (not unusual). It features a deep 'reptile' or bark texture, in flint, but the birdbath base well does not look right for Sklo Union with a plain, unground and thick rim, rather than the thinner ground rim normally seen on SU. It appears to have a four-part mould.
