How to Create a Crackled Effect on a Glass Bowl

Updated April 17, 2017

If you've ever dropped a piece of glass on the floor and it didn't break, you've noticed the tiny hairline cracks that form in the glass. Adding a crackle paint medium to glass will give glass this look without dropping the object on the floor. This technique can be used to turn ordinary glass objects into attractive pieces of art and add a touch of class and sophistication to any room in your home.

Prepare a work surface with newspaper and place your acrylic paints and crackle paint medium into separate disposable bowls.

Brush the darker acrylic paint over the entire outer surface of the glass bowl using a foam brush. Allow one hour for the paint to dry completely. If you are painting a large object, paint the sides first, let those dry and then paint the bottom.

Add water to the crackle paint medium. For smaller cracks, make the medium thin, and use less water to make bigger cracks.

Brush the crackle paint medium onto the glass bowl. Allow the medium to dry completely per manufacturer's directions. Again, apply to the sides first and then to the bottom once the sides dry.

Apply the second coat of paint using the lighter colour and let it dry. You will begin to see small cracks forming in the paint as the top layer of paint dries.

Apply a clear varnish to the glass object to keep the paint from chipping. Varnish can be applied using a brush or it can be sprayed on, depending on the manufacturer.
