Thirty three honey samples produced by four Melipona species from different areas of the State of Bahia, were analyzed with the aim to determine their physico-chemical characteristics, contributing to the establishment of standards for quality control. The majority of the average values for physico-chemical parameters fulfilled the quality criteria established by the Brazilian and international Legislations for Apis honey, except for moisture content, which afforded higher values. Concerning the high number of samples wich did not fit the limits for reducing sugars, it is necessary to define minimum values in order to characterize Melipona honeys, as well as criteria for use of diastasic activity.

In this research, we seek to corroborate the contributions of Chemistry to the identification, extraction and classification of minerals in the XVIII century, as well as, to approach the discussion that History of Chemistry shouldn't be understood in terms of a tight line of thoughts. For that, we analyze the work of Johann Andreas Cramer (1710-1777), Elements of the Art of Assaying Metals. Cramer proposed a method of mineral assaying based on the chemical behavior of the bodies, which allowed him to identify, extract and classify the minerals with more assertiveness.
