Not necessarily true. The representation of early trenchers appears to have
the crust intact. Representations of trenchers from the 13th Century on
show only the upper surface. They've been chipped, trimmed and squared, but
they still might have crust. Most of the books on manners date from the
period when trenchers were on the decline and were not in common use. The
other problem is no one actually states what is to be placed on a trencher.
They assume the user already knows.

There is no real baking time difference between whole wheat and refined
wheat. They have roughly the same amount of gluten, similar aeration and
similar density. Other flours tend to produce denser bread, but even there
the times are similar.

Usually metal tins come in either black or silver. Glass, stoneware and
terracotta also have their own temperaure characteristic. But all of them
fall roughly into the general time and temperature for baking bread with the
differences primarily noticed in the crust.

Enriched breads are more temperature critical. Errors in time or
temperature tend to show as under- or overbaking.

Shorter baking time. Special temperature control. Or both.

No. The baguette referred to is a modern loaf. It uses a fast yeast with
high initial temperature to get tremendous ovenspring, blasting the crumb
with large ragged cavities. After the initial baking time, the temperature
is dropped to get a fast heat decline in the oven. Gas ovens are preferred.
It is next to impossible to produce the effect in a heat mass oven.

That should have been "to" rather than "at."
