Fishes on a retailer mug

This is a mug I threw on the wheel using a cone 6 white stoneware body.

I used slip to create raised lines to draw fishes on the outside of the cup.

I made two cups that are this same design.

Mug A: 19 fl retailer oz, 5 inches tall
Mug B: 16 fl oz, 4.6 inches tall

The outside of the cup is glazed in a glossy blue glaze.

The inside of the cup is glazed with a food safe white glaze.
