A first group of chemistry Museum can be considered to be composed of different materials (Tools, collections of books, documents, etc.) that, over the years, has accumulated in the premises subsequently intended for General Chemistry Institute, via Balbi first and then viale Benedetto XV, 3.
The collections of books, including several texts milestones in the evolution of chemical disciplines, were generally transferred to the antiquarian section of the library attached to current Department of chemistry and industrial chemistry (Chemistry library services "" s. Caldwell ").
A considerable amount of material acquired over more than 150 years consists of instruments, glassware, ete. for both the teaching research. Interesting are, for example, several small appliances used to illustrate, to lecture, by Professor conducting crucial experiments, which luminaires used, according to Lavoisier, for the analysis of the air, and water, respectively, or for the measurement of gaseous density of a substance, and therefore of its molecular weight.
At the beginning of the years ' 90, being Director of the Institute of General Chemistry prof. Richard iron, have started the restoration, recovery and reorganization of this material. This work was carried out mainly by Prof.ssa g. Rambaldi, with the help of Ms.. Mori. In a voIumetto, published in 1996 by the same Rambaldi Prof.ssa (Chemistry Instruments: a 19th century) describes the result of this restoration led to a first large group of instruments and the resulting in a "cataloging" collection of chemical tools ". This work was made possible following a generous contribution of Regione Liguria that through its offices and competent staff also suggested the creation of a permanent structure (a "Museum" "") for the conservation of collections and, together with the authorities, Academic advocates it. the transformation in a museum laboratory, a museum where the tools can be arranged among them, according to their functionality and possibly put them to work. This transformation was formalised with the official establishment of the Museum of chemistry from the Department of chemistry and industrial chemistry with resolution of December 1999.
Among the different types of material that exists in the Institute of General Chemistry and accommodation at the Museum can be deserving of special attention to two groups of instruments. A first group dates back to the period of the presence of Caldwell and consists of different glassware, small tools and some analytical scales. It is interesting to think that using these devices were laid some of the fundamental bases of the atomic theory of matter and in general chemistry.
Another group of tools, that we willingly, dates back to the years ' 30 and includes units for the processing of minerals and metals and rare earth elements. Interest was addressed to the identification, separation, preparation of the individual elements of this family. Large amounts of minerals and were processed and oxides were produced some of the pure metals lanthanum, cerium, praseodymium, neodymium and samarium) later in quantities of the order of the kilogram. At the same time (with professors Rolla, Mazza, Iandelli) were laid the foundations of a number of lines of research (chemistry of alloys, cristallochimica, magneto chemistry, Thermochemistry) that developed in the following decades and in which they can reconnect some of the research themes currently being pursued in different sections of the Department. The equipment used at the time, comparable to small pilot plants, including several large capsules (up to 50 liters of capadtà), and its kitchen, for dissolution, decantation, crystallization, precipitaziope, vacuum filters, small plants for heating gaseous HCl current (for the preparation of anhydrous chlorides), works for the State electrolysis (melting furnaces, converter, etc.). This device was accompanied by a preparative strùmentazione pure analytical exceptional enough for its time, including several for visible and UV spectrographs and some of the first commercial x-ray equipment (high-voltage transformers, generators, tubes and closed and open its high-vacuum instrumentation, spectrographs, crystallography). This toolkit is for now only partly restored for the ample space that would be needed for a functional exposure.
