Showerthought: Fermentation vessel material could be altering my sourdough starter activity

I've been maintaining a sourdough starter for years in a glass jar. Lately, I switched to a ceramic crock and noticed slower rising times. What experiences do others have with different fermentation containers?

Ceramic crocks: turning eager yeast into procrastinators since forever!

Material science sneaking into baking (go figure) once delayed my rise for days.

Have you considered how the thickness of the crock might affect temperature regulation? I was just reading an old bread baking book that mentioned ceramic vessels often maintain a cooler core temperature than glass, which can slow down yeast activity. That could totally explain your slower rises! The author suggested that glass transfers ambient heat more quickly, creating a slightly warmer environment for fermentation. It's wild how material science sneaks into everyday baking like this!

Isn't it how we ignore physics in daily life?
