A method of manufacturing a molten metal-resisting ceramic fiber composition includes mixing ceramic fibers, a frit, ceramic additives, a low temperature binder, and water. The mixture is formed into a desired shape, preferably by being extruded through a die. The shaped mixture is baked at low temperature, and then is fired at high temperature. During firing, the low temperature binder is oxidized and the frit is melted so as to substantially coat the fibers and fuse them into a porous matrix.

Mineral samples are sealed in a nitrile barrier resin which prevents alterations in a sample between the time the sample is taken and the time the sample is analyzed. This resin provides chemical resistance to a core sample and good water vapor barrier properties and excellent oxygen barrier properties. The resin may be laminated with other materials to improve various properties.

Mineral sample preservation process

It has been discovered that nitrile barrier resin latexes containing a polyvinyl pyrrolidone compound are especially effective for coating various substrates.
