Cathedral

The windows in some medieval cathedrals show greater thickness at the bottom than at the top, owing to the slow flow of the glass under the influence of gravity.

Tesla died in 1943. His funeral seiMce was held in the Cathedral of St. John the Divine. As during his lifetime, controversy was not far away. The Serb and Croat mourners sat on opposite sides of the cathedral. 

Clusters of metal atoms can form colloidal suspensions. Colloidal clusters of copper, silver, and gold in glass are responsible for some of the vivid colors of stained glass in medieval cathedrals. Even aqueous suspensions of metal clusters are known (Fig. 8.45).

Vogt, Eric W. The curious case of Hermetic graffiti in Valladolid Cathedral ms. 

In this article, we will examine the frontispiece of the manuscript of a hymn by the Spanish composer Cristobal Galan (c. 1620-1684), entitled Si del alma las alas veloces (Valladolid Cathedral ms. 40/8). It consists of three nested squares framing the title, and two ink-drawn symbols above and below the title. Examined together with the lyrics, these elements reveal a syncretism of hermetic, alchemical images and words in an orthodox Roman Catholic devotional piece... 

Vincent Rillieux freely acknowledged his family. Norbert was baptized by a Roman Catholic priest in St. Louis Cathedral, where blacks and whites knelt side by side to pray. The child s birth was registered in City Hall in a mixture of French and English as Norbert Rillieux, quadroon libre, natural son of Vincent Rillieux and Constance Vivant.

Pollution is the release of something undesirable to the environment. By undesirable is meant something that is either harmful or unpleasant to some person, place, or thing. The industrial fumes that are destroying the stone artwork on the castles and cathedrals in Europe and the smog in the Los Angeles area are examples.

Question 8.5 What 19th-Century Disease Destroyed Cathedral Organ Pipes 113... 

Restorations of nineteenth-century organs in the cathedrals of northern Europe revealed a metal disease often attributed to the corrosion of tin. Chemically speaking, however, the structural change in the metal pipes is a completely different phenomenon. What aspects of chemistry must organ builders consider when attempting to achieve a particular acoustical character ... 

Pure tin exhibits two common forms in the solid state — a gray tin and a white tin. At temperatures above 13°C or 55°F, the more stable form of tin is the denser white tin. At lower temperatures, the white tin is slowly converted to the gray form, a more powdery substance. Prolonged exposure to the cold winter temperatures of northern Europe contributed to the loss of integrity and disintegration of many cathedral organ pipes. As a consequence of the progressive nature of the structural transformation, as the white tin metallic surface becomes covered with...
