Janez Vajkard Valvasor je svoje uradno šolanje opravil v Ljubljani. Kmalu po zaključenem pouku je mladi Valvasor skupaj z že uveljavljenim kemikom Joannesom de Monte Snydersom eksperimentiral na Dunaju. V naslednjih letih je nadgradil svoje poznavanje kemijskih lastnosti kovin za izdelavo tankostenskega kipa ob Dolenjski cesti v Ljubljani iz posebej v ta namen izumljene zlitine podobne tistim, ki so jih Japonci uporabljali za svoje zvonove. Iz svojih knjig in potovanj je zvedel podrobnosti o tedanjih japonskih zlitinah s katerimi si je pomagal pri lastnem postopku vlivanja kipa. Valvasor je v Ljubljani končal le nižje študije, saj so visokošolski pouk razvili komaj desetletje po njegovi smrti. Kdo so bili njegovi učitelji kemije, morebiti celo alkimije, in kje so Valvasorjevi profesorji pridobili potrebna znanja? Na voljo je pravzaprav le ena sama zanesljiva notica o njegovem ljubljanskem študiju datirana 15. 8. 1659, vendar je tudi iz nje mogoče spoznati učitelje, ki so ga utegnili navdušiti s svojim poznavanjem strukture snovi. Abstract Valvasor’s Contributions to Chemical Technology The Polymath Joannes Weikhard Valvasor (* 1641) conducted all his formal training in Ljubljana. Shortly after completing his schooling the young Valvasor experimented with the established chemist Joannes de Monte Snyders in Vienna. In the following years Valvasor developed his knowledge of the chemical properties of metals for the manufacture of thin-walled statue at Dolenjska Street in Ljubljana. He used the specially designed alloy similar to those endorsed by the Japanese for their bells. From his books and travels Valvasor learned the details of the Japanese alloys and used the data for his own process. According to the only available note about studies in Ljubljana College on August 15, 1659 Valvasor passed from the lower Latin Mary’s congregation to the higher Latin Mary’s congregation which means that he just finished the study of Syntax (higher Grammar) and was about to began his studies of poetics. He probably enrolled as the student-beginner in 1655/56 and graduated as the student of rhetoric in 1660/61. In this paper we will name Janez Vajkard Valvasor’s teachers of chemistry in his teenage years. Valvasor eventually finished just few years of his lower studies because as impetuous young man he decided not to continue his studies in any of the higher education institutions available outside Ljubljana. The leaders of Ljubljana lower courses who enabled and supported the work Valvasor’s formal teachers will be focused. The other important locals who helped Valvasor’s formal teachers to manage his teenage aspirations will be described. And last, but not least, the professor of Valvasor’s teachers will be named.   Keywords: Johan Weikhard Valvasor, Athanasius Kircher, Joannes de Monte Snyders, History of Chemistry, History of Schools, chemisemiotics.
