Hazel-Atlas Glass Co. (BRG/SHA encyclopedia) — acquired-mold passages

Source: https://bottleinfo.historicbottles.com/pdffiles/Hazel-Atlas.pdf (also at secure-sha.org/bottle/pdffiles/Hazel-Atlas.pdf; the old sha.org/bottle URLs are dead). Authors: Bill Lockhart, Beau Schriever, Bill Lindsey & Carol Serr, Bottle Research Group. Ingested: 2026-07-26 — focused excerpt only: the passages on re-cutting and running acquired molds, captured as precedent for the Three Rivers → Hazel-Atlas mold-transfer inference. The full chapter covers Hazel-Atlas corporate history and its complete mark catalog, which is out of scope for this wiki.

The “-Atlas-” cut into acquired molds

On early “-Atlas-” Mason jars (quoting Roller on jars made by Atlas Glass Co.):

“Since the ’- Atlas -’ is often lighter than the rest of the embossing, it is possible that it was cut into acquired molds.”

The Whitney ghost-embossing jars

Roller recorded a Mason jar variation with “ATLAS” ghosted above “MASON,” “WHITNEY (arch)” ghosted between “MASON” and “FRUIT,” and “PAT’D 1858” between “FRUIT” and “JAR.” Creswick likewise recorded ghosted WHITNEY/PAT’D 1858 jars, with and without ghosted ATLAS, noting “these jars would seem to indicate that the Atlas Glass Company made some of the Whitney jars.” The BRG authors add:

“We speculate that this could also mean that Atlas used some Whitney molds.”

Relevance to Three Rivers Glass

This is the documented industry pattern behind the Creswick-recorded “3 RIVERS {star} HA” jar: an acquiring or successor firm re-cutting its mark into another company’s molds and running them. It supports (without proving) the BRG inference that Three Rivers product-jar molds were transferred to Hazel-Atlas after the Ball Brothers took over the Three Rivers plant in 1936–37, and it establishes that molds were routinely treated as transferable capital assets at acquisition.
