17. Sea Glass - Bottles
Sea glass is a piece of broken glass that has been tossed for so long in the sand and ocean water that it becomes smooth. They even look like little blue pebbles sometimes, too. These are lovely, and lots of individuals turn them into jewelry or wind chimes.
In coastal homes, blue bottles are also common. People can find ancient apothecary bottles that were once hidden in the earth, depending on where you go. (Years before the collection of trash existed.) These bottles turn blue with age often, and on top of a dresser, they still look exquisite.
