This mug undergoes numerous steps to achieve this bark like look.  First it is thrown on the wheel, then coated in  couple spots with a chemical, torched, to create a crusted area then throwing continues and it is stretched from the inside out, breaking the exterior crust. Thus creating the wood look! Then the rest of the firing and glazing process is done, completing the final look....and yes it is microwave and dishwasher safe!  
Approximately 10 oz.
* actual mug may vary slightly from photo.
