Red cracks, yellow, and blue

Three nicely thin walled bowls were glazed with silver blue on the outside and yellow on the inside.

One of them broke in two while cooling down after glazing. I glued them together. 

It cannot be used for my breakfast anymore now that I marked the cracks with red acrylic. I did something similar to the cracked head in January. 

Same bowls with red back ground. Red eats the blue here.
