This is a hand crafted 12 ounce ceramic mug. A one of a kind creation by Paige Harper of Jacksonville Florida using a wood fired kiln. The wood firing process gives this 3d art a smoky, dark and mysterious look you cannot get using any other process. Mass produced products on store shelves will be nothing like this. What type or style of mug is this? I like to call the type "My Mug". That thing at home or the office that everyone knows is yours and to never..ever mess with.
