Glass-working tools

The tools necessary for most glass-working operations are simple and can best be described in relation to their uses. Probably the most useful general-purpose tool is an iron or steel spike about IJ inches... 

Working Tools ANn Apparatus,—The tools represented by Blaucoup.t, In his work On the Art of Glass, which was printed at London in 1G09, are almost precisely the same as those now in use and tho author s account of their mode of working might almost be taken os a description of the modern process. To those... 

Biocompatibility and bioactivity are outstanding properties on their own. Several glass ceramics have been developed which show high biocompatibility or bioactivity but which are not machinable with conventional metal-working tools [1.47]. 

In early work, Tool and Davies and Jones examined the structural recovery of glasses assuming that the departure from equilibrium depends upon a single ordering-parameter. Accordingly, the recovery was described by a single retardation time t. Here we define as the ordering parameter the volume departure from equilibrium expressed as a dimensionless variable 6... 

There are several forms of electrophoresis. In slab gel electrophoresis the conducting buffer is retained within a porous gel of agarose or polyacrylamide. Slabs are formed by pouring the gel between two glass plates separated by spacers. Typical thicknesses are 0.25-1 mm. Gel electrophoresis is an important technique in biochemistry, in which it is frequently used for DNA sequencing. Although it is a powerful tool for the qualitative analysis of complex mixtures, it is less useful for quantitative work.
