A bit of a disappointment
This book is at best a partial reprint of a 1901 text. Partial in that it references 41 Figures (Presumed to be illustrations) that are not reproduced. The text is dated, as one would expect from a more than 120 year old book being reprinted... But that it is a reprint rather than original work should have been made clear in the description.
On the plus side, as a view into historical glassblowing methods, it does offer some minor insights.
