Is there a marker that can be written on and the image will develop when the surface is heated?

Question

Seal

Interested in the existence of the subject, is there such a marker (felt pen) that can be written on any surface (for example, a mug), and the image will appear if the mug is heated

Answer 1

You can write with milk on paper :)

Answer 2

There is a thermal paint that appears on the label when the beer is cooled, if I am not mistaken, up to 12 degrees.
I have no doubt that you can find a similar paint that appears when heated, for example, to 60 degrees.
It remains to fill her with an empty felt-tip pen, which are sold in the children's departments.
