The 110-J paper is part of the Fiberfrax ceramic fiber paper
line which is manufactured by Unifrax corporation. In comparison to most
standard grades of fiber paper, the 110 is denser and more rigid. It
cannot be rolled or molded and must be used in its flat state. 110
paper is rated to 2300 F (1260 C), with a recommended operating temperature of
1900 F (1040 C). Its color is light tan and like most fiber papers it has a
different texture on each side. 110 paper is shipped in flat sheets that
are 48" by 42". The "J" designation refers to
the thickness of the paper, which is 1/8" (3.2 mm).
From a warm glass perspective, 110-J paper performs very well,
especially when compared to conventional "soft" fiber papers. It
can be cut fairly easily with a standard craft knife or scalpel. Although
you can sometimes get away without it, pre-firing to
1400 F (760 C) to burn off the binder is recommended. After fusing, the underside of the glass
picks up some of the texture of the paper, but 110-J tends not to stick to glass
at fusing temperatures (although there is some slight sticking,
especially with opaques). The paper is a bit brittle and must be
handled carefully, but with care it will last many more firings than
conventional fiber paper.
Like most fiber papers, 110 should be handled with care.
Loose fibers can be harmful if inhaled, and the fibers can irritate the
skin. A complete Material Safety Data Sheet is available at: http://www.unifrax.com/MSDSAPPR.nsf/byMSDS/M0061
