Why forget coffee? I don’t like coffee, or at least I haven’t tried one I like the taste let alone the smell of. That is why I wrote “forget coffee where’s the cocoa?” on my mug. I did 2 coats of color on all areas. I took this pic before sticking it in the oven.
As you can see I kept soapy water on hand in case of a screw up, this stuff might me permanent but, washing it immediately would have at least made it less noticeable. It isn’t perfect, but it will be a great test of the process.. It is currently in a 375 degree oven for 40 min, where it will also need to cool.
