🏺 缸 = 缶 (clay vessel) + 工 (gōng, phonetic) — a big clay jar
The 缶 radical on the left marks pottery/clay vessels; 工 on the right gives the sound gōng → gāng. So 缸 is a large earthenware jar or vat, the kind used to store water, wine, or pickles.
缸 — 缶 (jar/pottery) + 工 (gōng, phonetic)
缸 is a semantic-phonetic compound. The 缶 component on the right depicts an earthenware vessel and gives the meaning 'pottery jar or vat,' while 工 (gōng) on the left supplies the sound. It has long referred to large ceramic containers used to hold water, wine, or grain.
