How does placing a glass jar on a dark surface impact the required steeping time compared to a light surface?

Answer

It can account for an hour or more difference, often requiring less time.

Dark, non-reflective surfaces absorb radiant heat much more efficiently, allowing the water temperature to rise faster, thus potentially shortening the necessary steep time by an hour or more.
