In this article, from the characterization of technoscience of the English historian J. Pickstone and the recognition of the importance of models and modelling in research and teaching of chemistry, the term technochemistry is introduced as a way of chemical knowledge. With the above new possibilities, rethinking the chemistry curriculum is opened.

This essay follows recent work in environmental history to explore the history of recycling in physical sciences in Britain and North America since the seventeenth century. The term ‘recycling’ is here used broadly to refer to a variety of practices that extended the life of material resources for doing science in the early modern period. These included practices associated with maintenance, repair, exchange and the adaptation or reuse of material culture. The essay argues that such practices were common in early (...) modern science, and informed experimental spaces and techniques and the ideas that they generated. The essay considers some of the varied motivations that led to such practices, and concludes by examining the endurance of recycling in science since the end of the eighteenth century, particularly in recent efforts to create sustainable scientific research practices.

ABSTRACT An examination of the use of the word “laboratory” before the nineteenth century yields two striking results. First, “laboratory” referred almost exclusively to a room or house where chemical operations such as distillation, combustion, and dissolution were performed. Second, a “laboratory” was not exclusively a scientific institution but also an artisanal workplace. Drawing on the historical actors' use of “laboratory,” the essay first presents (some necessarily scattered) evidence for the actual correspondence between artisanal and scientific laboratories in the eighteenth (...) century. A particularly instructive case is the way the equipment of the laboratory of the Prussian Academy of Sciences was acquired. There was, in this case, a direct transfer of instruments, vessels, and materials from a pharmaceutical to an academic laboratory. The essay then argues that we ought to distinguish between two different experimental traditions in the early modern period: experimental philosophy and the laboratory tradition that meshed studies of nature with technological innovation.
