These vintage Fire-King Jadeite swirl mixing bowls were produced by Anchor Hocking during the 1950s.They feature a distinctive swirl or ribbed pattern in a translucent green milk glass known as Jadeite.These are typically found in nesting sets of three or four. The two included here are 8” and 9”. There is scratching visible on the inside of each bowl as well as a small chip on the inside of one of them. They display beautifully regardless.
