Try This Super-Simple DIY: Concrete Test Tube Vase

By  |  0 Comments

I’m a huge fan of the concrete and cement planter trend that’s been around for a while now so when I spied these cool concrete test tube vases on Pinterest I knew I wanted to try and make one. I already had a few glass test tubes that had been sent to me as part of a press kit and I’d hung onto them because I liked them but wasn’t quite sure what to do with them – until now.  I must admit I was a bit intimidated about this project at first because I’d never made anything out of concrete before. But after seeing how fab these vases turned out, it’s safe to say I’ve got the bug and I’m already planning my next concrete project.

See how simple is is to make this gorgeous vase in my video below. 



For this project you will need:

  • Ready-Mix concrete (mine was $8 from Bunnings)
  • Water
  • Containers (to use as moulds)
  • Small pebbles (to weigh the test tubes down)
  • Glass test tubes



  • If you don’t have test tubes simply grab an old jam jar or a small sized jar from the supermarket as these can look really cool too.
  • If you don’t have any pebbles to weigh your test tube down simply use tape to stick it to the bottom of the mould and hold it in place.
  • You can find glass test tubes on Amazon, TradeMe or simply Goolge “glass test tubes” to find your nearest supplier.
  • If you want to reuse your mould, coat the inside with cooking oil before pouring in the concrete. 
  • If you want your concrete to have a smooth surface then gently sand your vase when the concrete has fully cured.
  • I was impatient and didn’t wait for the concrete to fully cure before removing the moulds so if you want a perfect result be sure to wait until the concrete is rock hard first.
