The drying process of ceramic artifacts in pottery is carried out in preheated ovens aiming at homogeneity in the heat distribution. The objective of this work was to evaluate thermal gradients based on thermographic images of ovens in full activity at the ceramist pole in Iranduba-AM, in order to subsidize teachers and students of technological education who are interested in using new technologies in the teaching-learning process. Thermograms were analyzed on two different brick burning days. Possible thermographic responses were analyzed considering the climatic conditions in the study area, based on the homogeneous historical series from 1981 to 2010. The generated thermograms were analyzed in the Flir Tools program, 6.3v, being considered thermal patterns in decreasing order, identified by colors: white, red, yellow, green and blue. According to the climatology of the region, the month of August marks the lowest accumulated precipitation (mm) and the highest average air temperature (° C). The hottest target was the center of the oven (white pattern), with a temperature above 160 °C. Inside the ovens, temperatures reach values ??between 700 to 800 °C. The other layers had a normal and homogeneous thermographic pattern, decreasing the heat flow as the thermal conduction process took place. It is concluded that infrared thermography is an innovative technology that provides diagnosis and thermal responses of different targets with high precision, enabling the expansion of the use of technical-scientific tools in research and the connectivity of students and teachers to new resources in the teaching process-learning.
