The professional science master's, or PSM, got its start in 1997 as a way to better and more rapidly equip students with much-needed skills in the science, technology, engineering, and math (STEM) fields. Now nearly 300 PSM programs are offered by KGI and 128 other institutions.
Parkerizing, bonderizing, phosphating, or phosphatizing is a method of protecting a steel surface from corrosion and increasing its resistance to wear through the application of a chemical phosphate conversion coating.s for all chemical conversion coatings, the Parkerized surface must be completely covered with a light coating of oil to maximize corrosion and wear resistance, primarily through reducing wetting action and galvanic action.
In the presence of heat, the glaze becomes a glassy coating which fuses to the surface. Glaze Firing-Firing done after glaze has been applied to bisque or (occasionally) greenware to produce a glass-like surface. Greenware-Raw, dry, unfired clay. Characterized by being very fragile. Pinch Construction-A construction technique in which the clay is pinched and manipulated with the fingers into the desired shape. Scoring-To join two pieces of clay, it is usually necessary to prepare the surfaces of each piece to create a strong bond where they meet.
