This dot trap marble starts as a clear glass rod that is heated and formed into a puck. The puck is then pressed into brass pins to make a dotted geometric pattern. The dots are coated with colored glass to trap air bubbles. Then the whole puck is reheated and allowed to slump, which allows the colors to implode deep into the marble, causing a nebula to develop inside. The back is coated with black glass. ----------------------------------------------------------------------------------------------------------- -Marble size: 22mm ( 0.9 inch) -This marble is signed and dated on the bottom (BAM 2025) -Comes with a 3D printed plastic stand. -Photos were taken with indoor led lights. -Made in Northern Wisconsin. -Glass marbles have been annealed in a digital kiln to strengthen and remove all stress in the glass.
