Calme (lost Settlement)
A came is a divider bar used between small pieces of glass to make a larger glazing panel. There are two kinds of came: the H-shaped sections that hold two pieces together and the U-shaped sections that are used for the borders. Cames are mostly made of lead, zinc, copper, brass or brass-capped lead.Stevenson, Christine. (2004). ''Creative Stained Glass: Modern Designs & Simple Techniques.'' Lark Books. p. 12. . Of the metal strips, lead is softer and more flexible, making it easier to cut and bend. The harder metals are used to work with slightly curved lines and pieces that require greater structural support. They can also be used as border came, once again for stability and support.Shannon, George and Pat Torlen. (2002). ''The new stained glass: techniques, projects, patterns, designs.'' Sterling Publishing Company, Inc. p. 51. . Purpose Came serves three purposes:Berry, Leigh Ann. (2003). ''Basic Stained Glass Making: All the Skills and Tools You Need to Get Started.'' Stack ...

Lead Came Cross Sections02
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
