L Poling Ribal 'Morning Java' Coffee Mug Art in Hand... not just for the wall! Due to popular requests, my painting 'Morning Java' is now available on a coffee mug! A bit of info about the coffee mug manufacturer: The 15 ounce coffee mug is made solely in the USA by Cuppa. The coffee mug has a comfortable 4-finger sized handle and is industrial dishwasher, microwave, and UV safe. All of Cuppa's products pass Proposition 65 which means they are Non-Toxic. Using a proprietary dye-sublimation process, vivid, non-toxic vegetable based pigments are converted from a liquid into a gas and actually become part of the mug's surface. Each one of the cups have the artwork print hand-applied, as a result each is a unique work of art. There may be variations in the color print application before the cup is run through the manufacturing process.
