Abstract The first part of this research focuses on characterising the raw material to assess its suitability for production. The second part explores the use of acoustic emission (AE) as a method for monitoring crack formation during the drying process. Numerous experiments are conducted on heavy clay tile samples to identify acoustic emissions related to physical changes in the material during drying. The impulsive nature of the expected acoustic events suggests broadband excitation, while the wet clay itself strongly attenuates higher frequencies. As a result, the main energy is expected to be concentrated in the lower part of the spectrum. The hypothesis that acoustic events associated with the formation of macro- and micro-cracks fall within the audio frequency range is confirmed. As the brick and tile industry is energy-intensive, this approach supports UN Goal 12 by promoting responsible production and reducing drying scrap rate.
