Gray-King coke type
A simple coking test. Finely crushed coal is heated slowly in a glass retort and the shape, texture and appearance of the coke residue is compared to standards to give a letter, which is the Gray-King coke type. Values range from A (no coking characteristics at all) to G, then G1 to G9 (superior coking properties).
