Computer controlled digital microscopy—Wide area characterization of waste incorporated clay ceramics

A computer-controlled digital microscope coupled with a motorized optical system was used to analyze wide surface areas of a clay ceramics incorporated with 10% waste from paper recycling. This system acquires perfectly matched mosaic images covering the sample full surface and allows image analysis to interpret size, shape and spatial distribution of incorporated phases. In bright field, quartz particles, naturally existing in the clay, impair the paper waste observation. In dark field, the contrast disappearance of the quartz allows the paper waste to be analyzed.
