To create these realistic pop art burgers I have students start at the bottom and work their way up and usually I require them to have 6 or more layers to their burger. Each item added is shaped by hand or using tools to give each piece unique texture. I encourage students to be creative with what they're adding on-squirts of ketchup, pickle slices, maybe a side of fries. I have students stack but not attach them together. The only item that is actually scratched-to-attached on is the sesame seeds. Once bisque fired, each item is still separate which makes each item easier to glaze. After all the items are glazed, they are re-stacked and when glaze fired, the glaze will fuse the pieces together where ever they are touching.
