摘要：
An article of manufacture comprising a building panel such as ceiling tile for example includes, in addition to any by-product perlite fines, additional perlite fines in an amount sufficient to improve the fire resistance of the building panel over the fire resistance of the building panel without the additional perlite fines. In one aspect, the additional perlite fines can comprise at least approximately 3.5% perlite fines by weight. In another aspect, the additional perlite fines can have an average diameter of approximately 23 microns or less. Methods of manufacture related to the building panel also are disclosed.
