Recycling is important for the environment and flattening glass bottles is a creative solution for reusing those bottles in your house.

Learn a simple trick to flatten your glass bottles at home with the oven in this article.

How to Flatten Glass Bottles at Home in the Oven

While usually a kiln is used for flattening glass bottles, here’s a step-by-step approach on how to flatten glass bottles at home in the oven:

  1. Keep the toaster oven-ready, making sure none of its sides is touching anything else.
  2. In an oven tray, sprinkle some salt and place the bottle in the tray. Salt will restrict the movement of the bottle in the tray. If you still have the label on, keep the bottle with the label facing up.
  3. Place it in an oven and set the temperature to 200 degrees. Wait for two hours.
  4. Now, without moving the bottle, increase the oven’s temperature to as high it can go without setting it to broil. Let it heat for about 15 hours.
  5. The bottle should now be completely flat. Lower the temperature to 200 degrees and wait for another 15 hours.
  6. Now switch off the oven and let the bottle sit inside it for 5 hours. This will let it cool and settle.
  7. Take it out, and your flattened glass bottle is ready for display.  

Since this process involves high heating, please be careful while doing so and keep an eye on the oven for any flags. This is a fairly long procedure of waiting, but the repurposed glass bottles bring a distinctive look to your kitchen and house.
