What is Petri Resin Art and How Does It Differ?

The Key Difference: Creating the Petri Effect

Unlike standard resin pouring methods, Petri art uses drops of coloured alcohol inks, followed by a layer of white ink. As the white ink sinks through the resin, it drags pigment down with it, leading to remarkable organic shapes, soft tendrils, and depth within the cast piece. Each result is naturally unpredictable, giving Petri art its signature look and sense of movement.

If you’d like to try creating these effects yourself, the Petri Resin Art Starter Kit provides all the basics for beginners, including inks, resin, and clear guidance for getting started.

A Different Approach to Colour and Design

Whereas most resin art techniques focus on carefully controlled pours and surface designs, Petri art thrives on the interaction between ink and resin. After mixing resin and pouring it into a mould, coloured ink drops are added, with white ink applied over the top. The magic happens as gravity and chemistry combine to produce layered patterns and delicate cell-like structures within the piece, rather than just on the surface. The results evoke a sense of depth that other techniques rarely match.

When is Petri Resin Art the Right Choice?

Petri resin art is perfect if you want to create decorative objects, jewellery, or souvenirs where one-of-a-kind, abstract effects are a core feature. It’s especially appealing for gifts and small home décor items. Bear in mind that each piece will look different even with the same colours, so it’s well suited to artists and hobbyists who enjoy experimental or organic designs.
