I get asked what the colors look like after you bake the mugs you drew on with oil based sharpie markers. Here is the example mug I created with the colors. This mug has been baked. Oil based sharpies used. I have posts on my blog talking about the color change on things I have created. You can find those here  and here. You can always search the word sharpie in that search bar on the right of y blog. I never had a visual guide for people to see. It has been on my to-do list. Check that one off.
