The vintage MCM 1950s Blenko #5318 Charcoal Crackle Glass Sheaf Vase is a hand-blown piece of mid-century modern decor. Made in North America, this original piece features a glossy finish with a crackle glass design, characteristic of the era. The vase is considered charcoal colored but can look blue or even turquoise in the light. The Blenko 5318 Sheaf Vase appeared in the 1954 Blenko catalog which is shown in the last photo.
