Abstract This work reports and compares the structural crystallochemical transformations occurring during the microwave and conventional porcelain manufacture. Batches of greenware (just dried) porcelain pieces are microwave and electrically fired at increasing temperatures, from 420 °C up to 1100 °C. Crystallochemical transformations are identified by XRD analysis, and compared the results from samples microwave and conventionally fired. Microwave fired samples show the full and rapid collapse of kaolinite structure for firing temperatures just above 500 °C, whereas the collapse of kaolinite structure of the electrically fired samples is progressive, from about 500 °C up to 950 °C. Muscovite structure totally collapses at about 950 °C for microwave fired greenware samples, whereas muscovite structure total collapse only occurs at about 1050 °C for electrically fired greenware samples. Microwave and electric firing lead to appreciable differences in the sanidine – orthoclase – microcline structural transformations. Mullite formation could be identified in the microwave fired samples at temperatures 50 °C lower than in the electrically fired ones, especially for the conventional firing temperatures above 1050 °C, the same temperature reported in the literature.

Resumen: La actual Ciudad Universitaria de Madrid se sitúa sobre el que fue uno de los Reales Sitios madrileños, el de La Florida y La Moncloa. Este artículo tiene como objeto contestar a la pregunta ¿qué había antes?, centrándose en el edificio de la Real Fábrica de Porcelana, que posteriormente se convertiría en el primer edificio universitario de la zona, la Escuela de Ingenieros Agrónomos, antes de que el campus siquiera se imaginase. Se enfoca, además, el trabajo no solo desde el punto de vista histórico, sino también desde el análisis arquitectónico, y se utiliza el dibujo como instrumento metodológico para establecer hipótesis que nos permitan comprender cómo fue ese lugar y cómo se ha transformado hasta llegar al edificio que conocemos hoy día.Abstract: Madrid’s Ciudad Universitaria is located on the grounds of the ancient La Florida and La Moncloa Real State, which was one of the madrilian royal properties. This article aims to answer the question what was there before?, focusing on the building of the Royal Porcelain Manufacture. It would later become the first university building in the area –the School of Agricultural Engineers–, even before the campus was envisaged. We approach this work not only from a historical perspective, but also from the architectural analysis, using drawing as a tool to understand how this place was and how it developed towards the current building we know today.
