Casting Concrete Vases

Casting concrete vases is an easy, smaller-scale project that allows you to incorporate the modern aesthetic of concrete décor into your home’s design through ornamentation.

Project Instructions

When working with cement-based products, always wear eye protection and waterproof gloves.

Step 1
Cut off the bottom of the plastic bottles.

TIP: If using a glass bottle, make sure it has a wide mouth so that it may be filled from the top.

Step 2
Drill a hole in the caps of the bottles. Make sure that it will tightly accommodate a pen, candle or a test tube.

Step 3
Mix the concrete and spoon it into the bottles. Make sure to push the wet concrete down into the bottle.

TIP: Make sure the bottles are clean, before pouring. Also, place them in a stationary position where they can be filled without falling over.

Step 4
Vibrate the full bottles to bring any air bubbles to the surface

Step 5
Allow the concrete to cure for at least 24 hours. Then, remove the plastic bottles with a box cutter and diagonal pliers.

TIP: If cast in glass, the bottle will need to be broken, to release the vase. Wait at least 4 days before removing glass bottles, so that the concrete can cure and reach a higher strength. Then, lightly tap the glass with a hammer.

Step 6
Remove the pen, candle or test tube.

TIP: To remove the pen or candle, try applying heat before removing it. For the test tubes, use the diagonal pliers to crush them into fragments that can be poured out.
