Crystalvac Jars — Waffle Glass vs. Smooth (Looking for the “Older Brother”)

Two empty square jars with screw necks, shot top-down on OSB: the left jar’s body is covered in a raised waffle or grid texture; the right jar is smooth clear glass of the same footprint. The Instagram caption framed the hunt for Crystalvac’s “older brother” — if common quart stock molds were one size, the one-pound Hoffmann-Hayman vacuum jars may sit on a custom or customer-owned mold that runs larger. This photo doesn’t settle the genealogy, but it documents the texture variant collectors use to sort Three Rivers–era production from later generic square jars.
