This book describes in detail how one proceeds to set up a burner, adjust flame size and temperature, and then use it discover the properties of molten Pyrex glass by the construction of a series of "artistic" figures from glass rods. Similarly, step by step instructions are given for the joining of glass tubes, making T tubes and other simple forms needed for parts in the step by step description of fabricating cold fingers, condensers, etc. The technique of "annealing" glass constructs to reduce stress/strains setup by uneven cooling is emphasized throughout.
