Porphyry

== Description ==
In ancient Egypt, porphyry was the name for a dark purplish-red igneous stone that was very hard and had many small, but visible crystals embedded in a fine-grain matrix. Porphory was quarried from the eastern Egyptian desert near Mons Porphyrite. Currently, the term 'porphyry' describes any igneous stone with this texture. Colorful porphyritic stones have been used for buildings, sculptures, and small ornaments. They are red, purple, and green colors and can be polished to a high gloss. Porphyritic stones have been traditionally used to make mullers and slabs for grinding pigments.

Portland cement

== Description ==
A type of hydraulic cement that hardens under water. Portland cement was patented by Joseph Aspdin of Leeds, England in 1824. It was called portland cement because it resembled the grayish colored building stone obtained from the Isle of Portland, England. From 1865, it was imported to the U.S. from England until manufacturing began in 1872 in America. Portland cement is made from limestone mixed with clay then baked in a kiln (1300-1500 C) until it partially vitrifies. The resulting product (calcium silicate) is powdered for use as a cement. Portland cement sets to a hard impermeable solid when mixed with water. Analysis indicates that the cement contained 60-64% lime, 20-24% silica, 6-10% alumina, and 3-5% iron oxide, with small amounts of magnesia, sodium, potassium, and sulfur. Portland cement is often mixed with aggregated to form mortar and concrete. It is resistant to water and has been used as a fill for large voids in outdoor sculptures (Thornton, 1988). Portland cement has been used for skyscrapers, dams, bridges, roads, and other structures. 
Currently, in the U.S. five types of portland cement are standardized by the American Society for Testing and Materials (ASTM): 
* Type I (ordinary): used in general construction such as sidewalks 
* Type II (modified -omitted in other countries): used near water such as sea walls and building foundations 
* Type III (high-early-strength or rapid hardening): used in cold-weather construction 
* Type IV (low-heat): used for massive structures such as dams 
* Type V (sulfate-resistant or Ferrari cement): used for foundation in high sulfate soils.

Portland stone

== Description ==
An unstandardized term that usually refers to a limestone quarried on the Isle of Portland, England. Portland stone has been quarried since the 12th century. It became popular in the 17th century when Christopher Wren used Portland stone to rebuild St. Paul's Cathedral after the Great Fire of London in 1666. Stone from the isle of Portland was imported to North America in the 18th century (Bucher 1996). The creamy white, oolitic limestone is typically fine-grained with an open texture. In the United States, the name Portland stone is also used for a brownstone quarried near Portland, Connecticut. 
See Connecticut brownstone.

Portland limestone; Connecticut brownstone; Portland Stone (Deut.)

Potassium

== Description ==
A naturally occurring metallic element. Potassium has an abundance in the earth's crust of 2.6%. It was discovered by Sir Humphrey Davy in 1807. Potassium is a soft, silvery-white metal that rapidly oxidizes in moist air. It does not occur in nature in the free state because it is highly reactive. It is found mainly as potassium chloride (sylvite) and in clays (orthoclase, microcline). Major potassium salt deposits include the Great Salt Lake and Salduro Marsh in Utah and the Dead Sea between Israel and Jordan. Potassium salts are used to make fertilizer and hardened glass.

Potassium-argon dating

== Description ==
A dating method for minerals based on the measurement of the ratio of radioactive potassium to radioactive argon. Radioactive potassium decays to form radioactive argon at a known rate. Argon is rare since it can readily escape to the atmosphere. Thus, its presence in a freshly opened stones is assumed to be due to the decay of potassium. The age of meteorites and volcanic stones are measured by this method.
