Add DIY Permanent Volume Markings On A Metal Container

Add DIY Permanent Volume Markings On A Metal Container

Need more measuring options in the kitchen? A Redditor shared a neat trick to make permanent markings on any metal tumbler or saucepan. Most of the items needed should be in your house, or you can pick them up for very little.

Here’s what you’ll need:

  • 1/4 cup vinegar
  • 1/4 teaspoon salt
  • 9 volt battery
  • Cotton bud
  • Adhesive stencils

Make a solution of the vinegar and salt. As the uploader mentions, the method uses electrolytic acid etching, basically removing metal from the pot. You’ll need to hook up the positive lead of the battery to the pot and the negative lead to the cotton bud. The negative lead has to be attached in a way that it touches the vinegar solution when the Q-tip is dipped into it. To make the etchings, just dip the Q-tip and scrape it against the pot.

If you hear some sizzling or see some bubbling, you know it is working. It only takes a few seconds of contact to permanently dissolve some metal. I suggest testing it on another piece of the same metal that you don’t care much about before etching your kettle.

The adhesive stencils are to mark the volume measurements on the cup. The best option would be to pour water from a measuring jug into the pot and marking the measurements you need.

The Reddit thread has plenty of useful suggestions by commenters, while the Imgur link has step-by-step instructions with pictures from the original uploader.
