Ceramaguard is a commercial ceiling tile that is manufactured by
Armstrong. It is made to be used in commercial suspended ceilings
where fire resistance is a priority. Its color is white and it is
finished on one side with a factory-applied vinyl plastic paint.
The product is manufactured in sheets that are 2 feet by 4 feet (600
by 1200mm) and in 2 feet squares. It is 5/8" thick (around 16mm).
The surface of most Ceramaguard is covered with small fissures,
although unperforated Ceramaguard is sometimes available. The
unperforated variety is not perfectly smooth, but it is fairly free
of deep fissures or cracks. Either type, perforated or unperforated,
will work well for fusing and slumping applications.
From a warm glass perspective, the principle
use of Ceramaguard is to make drop rings and similar molds.
Ceramaguard is easier to cut than fiber board; you can use a
hacksaw, a regular saw, or even a craft knife or similar tool. It
can also be easily worked with tools such as a table saw or a power
drill. Cutting it may produce a lot of dust, so it's a good idea to
wear a mask. Once cut, Ceramaguard will not continue to deteriorate
the way that fiber board can, although the edges can get a bit
banged up from handling.
