Discla irocr: The laboratory can only verify the conccnealion of silica on rhe filler and not the final concentrstion due to data obtained by non-laboratoty personnel. In the absenoc ofa bulk dost sample, the specific form of crystsiiioc silica can not he determined, Hence, alphu-quartz, the most prevalent form ofcrystalline silica, will bea.asuracd.
