When small amounts of paraffin are ready to be solidified, they can be cooled immediately in water, preferably at a temperature of 10-15°C. Make certain that a solidified scum has formed over each potential block before dipping it below the surface of the water. Water colder than 10°C causes the block to contract too strongly and it may finally crack. Furthermore, normal crystals may form in the center, but abnormal ones in the periphery of the block. The perfect block is one in which the paraffin crystals are contiguous with each other and the paraffin appears clear and homogeneous. Paraffin may contain 7-15% air dissolved in it and will appear clear Avhen that air is distributed evenly through its mass. But pockets of air produce milky spots, a condition called "crystal- ; Either slow hardening of the block in the air, or too rapid cooling may cause this effect, particularly in the case of large Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Humason, Gretchen L.
