glass facts Selected as the most interesting among chemistry related questions in Chemistry quiz This photo has been taken at seaglass beach in Hawai'i. How is the seaglass formed?From garbage. Sea glass beaches are created from years of dumping garbage into an area of coastline. Sea glass begins as normal shards of broken glass that are then persistently tumbled and ground until the sharp edges are rounded. Created by: life-o-holicHawaii facts » What kind of material is this cooktop made of?Glass-ceramic materials share many properties with both non-crystalline glass and crystalline ceramics. The negative thermal expansion of the crystalline ceramic phase can be balanced with the positive expansion of the glassy phase. At a certain point (~70% crystalline) the glass-ceramic has a net expansion near zero and can sustain repeated and quick temperature changes up to 1000 °C.Created by: Bob Stanleymaterials facts » What was added to this glass to make it blue?Cobalt. Powdered cobalt glass, called smalt, has been historically important as a pigment in painting and pottery. It is colored to a deep powder blue hue using cobalt ions derived from cobalt oxide. Cobalt aluminate can be used in a similar way, and is now more common, often known as "cobalt blue".Created by: globalquiz.orgcolors facts » What are these vintage glasses for?Champagne. Legend has it the shape of the glass was modelled on the breast of Marie Antoinette. The broad surface area allows champagne to lose its carbonation more quickly, making it not suitable for the current style of very dry champagnes. It therefore fell out of fashion except for traditional occasions such as weddings, where it is often stacked in layers to build a champagne tower.Created by: globalquiz.orgalcohol facts » What are these glasses for?Champagne. The narrow bowl of the champagne flute is designed to retain champagne's signature carbonation, by reducing the surface area at the opening of the bowl.
