text: where is a good website where i can find information about thilorier? it's for an paragraph essay so it has to be a fair amount of info on him? i wasn't able to find a specific site with much more than few sentences about him  charles thilorier was a scientist who gave the earliest description of solid carbon dioxide. in 1834 he opened a pressurized container of liquid carbon dioxide, only to find that the cooling produced by the rapid evaporation of the liquid yielded a "snow" of solid co2.  dry ice is the trademark for carbon dioxide in its solid form, frozen at -109.3° f or -79.5° c. it is primarily used as a refrigerant. dry ice does not melt but goes directly from a solid to a gas in a process called sublimation. it is generally accepted that french chemist, charles thilorier, was the first to record the appearance of it in 1835. the dry ice corporation of america first trademarked the name dry ice in 1925
