Glass questions This is a list of recently added questions about glass. 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.orghard 53% winewine1518beerbeer344champagnechampagne2890whiskywhisky609alcohol riddles » What are these glasses for?Champagne.

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 Stanleyaverage 61% glassglass1469ceramicceramic4653metalmetal549glass-ceramicglass-ceramic10865materials riddles » Play chemistry quiz and see all the questions.
