The Methods of Glass Blowing and of Working Silica in the Oxy-Gas Flame For the use of chemical and physical students

In the later pages of this Chapter it will be assumed that the operations first described have been mastered. The beginner should therefore practise each operation until he find...

All the varieties of glass that are ordinarily met with contain silica (SiO_{2}) associated with metallic oxides. In a true glass there are at least two metallic oxides. The unm...

In Chapter III. the simpler operations used in making the separate parts of which apparatus is composed have been described. In this Chapter finished apparatus will be described...

=Introductory.=--Vitreous Silica was made in fine threads by M. Gaudin in 1839,[22] and small tubes of it were made in 1869 by M. A. Gautier, but its remarkable qualities were n...

Although the subjects to which this concluding chapter is devoted do not, properly speaking, consist of operations in glass-blowing, they are so allied to the subject, and of su...

setting up complete apparatus, full explanations of the construction of two or three typical pieces of apparatus being given as examples, and also descriptions of the modes of m...

=Introductory.=--I shall endeavour to give such an account of the operations required in constructing glass apparatus as will be useful to chemical and other students; and as th...

The diagrams given below show the sizes and thickness of the glass tubes most frequently required. In ordering, the numbers of these diagrams may be quoted, or the exact dimensi...
