Using petrography, XRD and SEM-EDX, we: 🔹 Identified 3 main fabric groups for each phase 🔹 Documented differences in temper & firing regimes 🔹 Proposed that all raw materials were locally sourced (no imports!)

New at PB: Artist, activist, & writer Warren Cariou visits @josevergara.bsky.social’s class for a conversation about his writing, his petrography (photographs produced with bitumen), Indigenous land relations, and the need for local control over energy.
“Suddenly, the New Story Was There”
“I had seen a lot of bitumen in the devastated landscapes of the bitumen mines. But seeing it here, in such a mundane and tranquil setting, surprised me. That was when I first understood that this…

Have a random July birthday of a historic scientist:
July 14 is the birthday of Florence Bascom, (1862–1945), considered the first women geologist in the United States. She was an expert in crystallography, mineralogy, and
petrography.
