Opalescent glass panels are really fascinating. When you see one, you'll first be amazed by the streaky colors and then you'll want to crack a small piece and eat it! They kinda look like large sheets made of melted candy and that glossy surface makes you somehow happy. Plus, the making process is one of the most relaxing visual experience on earth. If you'd like to see, here's a video from Kokomo Opalescent Glass, the oldest stained-glass manufacturer in the US producing opalescent glass sheets for 130 years. Hope you enjoy!
