David is correct (as usual). Bluestone and Nanoform are not ceramics.

There is disagreement in the technical literature as to the correct
definition of ceramics but a useful definition I have seen is:

Any inorganic, nonmetallic solids processed or used in high temperatures.
The wide range of materials that fall within this classification includes
ceramics that are composed of clay minerals, cement, and glass. These
materials are typically insulative to the passage of electricity and heat,
and are more resistant to high temperatures and harsh environments than
metals and polymers (plastics). With regards to mechanical behavior,
ceramics are hard but very brittle.
