Atlas of charcoal-based grilling fuels components

This atlas features compilation of over 600 microscopic images taken between 2019 and 2021 while the authors were developing methodology of using reflected light microscopy in identification of charcoal-based grilling fuels constituents. These photomicrographs provide documentation of the composition of the fuels and demonstrate the array of impurities that can be present. As such, this atlas is a valuable source of information for anyone interested in grilling, pellet fuels, optical microscopy, and quality assessment techniques.
