Can overcooked caramel be harmful?
I think what your looking for is called poured sugar oil moulds(rings) that you want to use ant shape is okay then use 2 lbs sugar,1 lb water, 6.55 ounces of glucose  and food colouring if you want.make a syrup with the three and then boil until it reaches 260F add food colouring continue to boil until temp. reaches 330F  plunge the pot into a cold water bath to stop the cooking.remove from water and let stand 2-3 minutes to thicken. Pour mixture into moulds until 1/4 inch thick. Once edges have setenough remove the ring. Use a little reheated sugar to attached pieces together like a glue.this can be used as a base for any center piece you want to create with other sugar pieces
