3. On the Composition of Old Scotch Glass

Extract

We have recently been engaged in the laboratory of the Industrial Museum in executing some analyses of glass, which, as of general interest, I lay before the Society. The analyses in question have been made by Mr Bloxam, the official laboratory-assistant, and it is desirable first to mention with what object they were undertaken. I have limited the investigation in the first place to common bottle glass and window glass in use in Scotland, and so far as could be ascertained, also manufactured in Scotland. As yet we have only overtaken six varieties, and the full import of their analyses will not appear till additional examples have been examined.
