Fragmentation of glass

A Pyrex bottle can be used it must be enclosed to prevent possible injury by fragments of glass in case of explosion. 

The quantity of debris received is frequently a great obstacle to the successful recovery of an identifiable amount of flammable liquid. Small amounts of dry, charred ashes, dry fragments of paper, and small fragments of glass oould at the very best only contain extremely small quantities of accelerants and could easily preclude the possibility of effecting an identification of the material. 

Chemometric methods such as analysis of correlation coefficients, cluster analysis or neural network analysis are used, for example, in the classification of fragments of glass on the basis of their elemental composition or refractive index. Such methods allow the test material to be classified into the appropriate group of products on the basis of the measured parameter. 

Even after taking the usual precautions, it sometimes happens that the silver halide is mixed with fragments of glass, which will, of course, cause the percentage of halogen to be too high- If the substance under examination is silver chloride, and the presence...
