Ebook: Manual of Laboratory Glass-Blowing

Laboratory glass-blowing, like most arts, tends to change its objectives and methods in response to changing demands on its practitioners and changing resources open to them. Whereas many of the manuals of the past dealt extensively with the making of such things as stopcocks and even thermometers, and had little or nothing to say of the apparatus used in, for example, vacuum work, it is now possible to buy many of the things that formerly had to be made; and the laboratory glass-blower is more often called upon to produce special apparatus for special purposes. The operations described in this book reflect this change.
