For standard warm coffee drinks, there are a goodly amount of standard mugs that are made from glass instead of porcelain. Some glasses are available in tinted colors, such as juniper or cobalt. These are a nice way to add a little flair to the morning coffee routine. For a cup of joe with a little extra kick, consider making an Irish coffee. If this is a drink specialty you offer, remember to purchase the glasses that are deemed suitable for Irish coffee as the design is meant to keep the liquor better mixed with the coffee and the footed design is synonymous with the alcoholic drink. It is crucial to remember that although these glasses are meant for serving hot drinks, they can crack if exposed to extreme temperatures too quickly. Placing a metal spoon in the drink in the cup before pouring the hot beverage will allow the metal spoon to absorb some of the heat and lessen the risk of the glass cracking.
