It is a little amusing that nobody has mentioned the traditional, and
most common "non-carbon reductive material": water They might not
teach this in chemistry 101 (set your books down Ivor and Bruce. ;^)
), but if you have wood fired at all, you soon learn to appreciate
the reducing characteristics in water, including the water found in
wood fuel.

*If you do a search on the topic, with Dr. Pamela Vandiver's name too
(Materials Archaeologist at the Smithsonian Institution) you can see
that she has lecture around the country on the topic. Below is a
sample from an MIT conference:

To understand the relationship of a property like strength to high
temperature firing processes, we will investigate a Chinese technology
begun in the Shang dynasty at about 1600 B.C.E. This technology has been
continued to the present and is based on the use of water for the
hydrogen reduction of pottery, roof tiles, bricks and even the
terracotta warriors and horses of Qin She Huang Di's mausoleum.
