supports: Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term "masonry" can also refer to the units themselves. The common materials of masonry construction are brick, building stone such as marble, granite, travertine, and limestone, cast stone, concrete block, glass block, and cob. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can significantly affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. Weiskittel - Roehle Burial Vault is a historic burial vault located in Section P , Loudon Park Cemetery , Baltimore , Maryland . It is a rectangular structure made of cast iron built into the side of a hill , constructed to look like ashlar masonry and painted gray . It was made as the tomb of Anton W. Weiskittel who died in 1884 , a Baltimore iron founder . It was listed on the National Register of Historic Places in 1976 . In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid (pronounced: "/tæpzd/") in American and Canadian English but as a trapezium in English outside North America. The parallel sides are called the "bases" of the trapezoid and the other two sides are called the "legs" or the lateral sides (if they are not parallel; otherwise there are two pairs of bases). A "scalene trapezoid" is a trapezoid with no sides of equal measure, in contrast to the special cases below. Marcus Vitruvius Pollio (born c. 8070 BC, died after c. 15 BC), commonly known as Vitruvius or Vitruvi or Vitruvio, was a Roman author, architect, civil engineer and military engineer during the 1st century BC, known for his multi-volume work entitled "De architectura". Ashlar is finely dressed (cut, worked) masonry, either an individual stone that has been worked until squared or the masonry built of such stone. It is the finest stone masonry unit, generally cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut on all faces adjacent to those of other stones, ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect. Graphite, archaically referred to as plumbago, is a crystalline form of carbon, a semimetal, a native element mineral, and one of the allotropes of carbon. Graphite is the most stable form of carbon under standard conditions. Therefore, it is used in thermochemistry as the standard state for defining the heat of formation of carbon compounds. Carbon (from "coal") is a chemical element with symbol C and atomic number 6. It is nonmetallic and tetravalentmaking four electrons available to form covalent chemical bonds. Three isotopes occur naturally, C and C being stable, while C is a radioactive isotope, decaying with a half-life of about 5,730 years. Carbon is one of the few elements known since antiquity. Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through; grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks; ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. In geometry, a cuboid is a convex polyhedron bounded by six quadrilateral faces, whose polyhedral graph is the same as that of a cube. While mathematical literature refers to any such polyhedron as a cuboid, other sources use "cuboid" to refer to a shape of this type in which each of the faces is a rectangle (and so each pair of adjacent faces meets in a right angle); this more restrictive type of cuboid is also known as a rectangular cuboid, right cuboid, rectangular box, rectangular hexahedron, right rectangular prism, or rectangular parallelepiped. Iron is a chemical element with symbol Fe (from ) and atomic number 26. It is a metal in the first transition series. It is by mass the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most common element in the Earth's crust. Its abundance in rocky planets like Earth is due to its abundant production by fusion in high-mass stars, where it is the last element to be produced with release of energy before the violent collapse of a supernova, which scatters the iron into space. In chemistry, a carbide is a compound composed of carbon and a less electronegative element. Carbides can be generally classified by chemical bonding type as follows: (i) salt-like, (ii) covalent compounds, (iii) interstitial compounds, and (iv) "intermediate" transition metal carbides. Examples include calcium carbide (CaC), silicon carbide (SiC), tungsten carbide (WC) (often called simply "carbide" when referring to machine tooling), and cementite (FeC), each used in key industrial applications. The naming of ionic carbides is not systematic. Loudon Park Cemetery and Loudon Park Funeral Home, Inc. in Baltimore, Maryland, are locally owned and operated. Both the Cemetery and the Funeral Home became privately owned in 2014 when they were acquired from SCI (Service Corporation International.) Loudon Park Funeral Home, Inc. was built on the grounds of the historic cemetery by Stewart Enterprises in 1995. SCI (Service Corporation International) acquired Stewart Enterprises in 2013. The expanded cemetery was incorporated on January 27, 1853 on 100 acres of the site of the "Loudon" estate, previously owned by James Carey, a local merchant and politician. The entrance to the cemetery is located at 3620 Wilkens Avenue.  Tin is a chemical element with the symbol Sn (for ) and atomic number 50, is a post-transition metal in group 14 of the periodic table. It is obtained chiefly from the mineral cassiterite, which contains tin dioxide, SnO. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable +4. Tin is the 49th most abundant element and has, with 10 stable isotopes, the largest number of stable isotopes in the periodic table, thanks to its magic number of protons. It has two main allotropes: at room temperature, the stable allotrope is -tin, a silvery-white, malleable metal, but at low temperatures it transforms into the less dense grey -tin, which has the diamond cubic structure. Metallic tin is not easily oxidized in air.
