Glass is in widespread use largely due to the production of glass compositions that are transparent to visible light. In contrast, polycrystalline materials do not generally transmit visible light. The individual crystallites may be transparent, but their facets (grain boundaries) reflect or scatter light resulting in diffuse reflection. Glass does not contain the internal subdivisions associated with grain boundaries in polycrystals and hence does not scatter light in the same manner as a polycrystalline material. The surface of a glass is often smooth since during glass formation the molecules of the supercooled liquid are not forced to dispose in rigid crystal geometries and can follow surface tension, which imposes a microscopically smooth surface. These properties, which give glass its clearness, can be retained even if glass is partially light-absorbingi.e., colored.
What force gives glass its surface texture?
surface tension

Despite Tom's conviction, Bob Ewell is humiliated by the events of the trial, Atticus explaining that he "destroyed [Ewell's] last shred of credibility at that trial." Ewell vows revenge, spitting in Atticus' face, trying to break into the judge's house, and menacing Tom Robinson's widow. Finally, he attacks the defenseless Jem and Scout while they walk home on a dark night after the school Halloween pageant. One of Jem's arms is broken in the struggle, but amid the confusion someone comes to the children's rescue. The mysterious man carries Jem home, where Scout realizes that he is Boo Radley.
Who did Bob Ewell attack during the story?
Jem and Scout

Nuestra Senora del Sagrado Corazon ("Our Lady of the Sacred Heart"), also known as Iglesia Punta Carretas ("Punta Carretas Church"), was built between 1917 and 1927 in the Romanesque Revival style. The church was originally part of the Order of Friars Minor Capuchin, but is presently in the parish of the Ecclesiastic Curia. Its location is at the corner of Solano Garcia and Jose Ellauri. It has a nave and aisles. The roof has many vaults. During the construction of the Punta Carretas Shopping complex, major cracks developed in the structure of the church as a result of differential foundation settlement.
Between what years was the Iglesia Punta Carretas built?
between 1917 and 1927
