From what I've read Diamond Alkali which became Diamond Shamrock was founded in 1910 by three glass-making companies (Macbeth-Evans Glass Co. of Pittsburgh, C.L. Flaccus Glass Co. of Pittsburgh, and Hazel-Atlas Glass Co. of Wheeling, WV) with the purpose of manufacturing soda ash—a major raw material in glass production. The new firm was incorporated on March 21, 1910 in West Virginia, with the company's headquarters established in Pittsburgh. With a capitalization of $1.2 million, a soda ash plant was built in Painesville Township, Ohio. So Diamond Alkali/Shamrock didn't manufacture glass they just provided Soda Ash to Macbeth-Evans, Flaccus & Hazel Atlas so if your bowl is from the 1970s that narrows down the manufacturers to Macbeth-Evans or Hazel Atlas & in looking at older -pre-1960s production from both companies in Hazel-Marie Weatherman's book, well honestly either one could have made your bowl as both made virtually 100% utilitarian mass produced glassware. Unfortunalely both companies made probably well over 100 bowl designs so it will not be an easy search. I would try eBay using Macbeth-Evans large bowl then Hazel Atlas large bowl to try to find a possible match. All I can say is good luck.
