How to Apply: Step-by-Step Guide for Petri Dish Resin Art
The magic of Petri Dish resin art lies in its technique. Here’s how to get started for impressive, organic results:
- Mix and pour your resin into a mould or shallow dish. Allow it to rest for 20–30 minutes until slightly viscous (timing depends on temperature).
- With a dropper or pipette, add coloured alcohol inks from the Petri Art Set or “Jacquard Pinata” Alcohol Ink Blast Effect directly into the surface.
- Apply a drop of white alcohol ink (such as from “Jacquard Pinata” White Alcohol Ink) after each colour. This causes each puddle to push through the coloured layer, forming characteristic blossom and cell-like effects.
- To intensify cell movement, optionally add a drop of “Resi-Blast” Cell Effect Additive or “Magic Drops”. This will stimulate more dramatic lacing and blooming patterns.
- Customise your base colours with the “Colourfun Set” for unique tones beneath the Petri blooms.
- Let the resin cure undisturbed for best clarity and multi-dimensional depth.
Safety Tip: Only use inks and additives tested for compatibility with epoxy resin. Avoid exceeding recommended concentrations to maintain transparency and structural integrity.
Tips for Perfecting the Petri Dish Resin Effect
Mastering this technique involves understanding product behaviour and timing. Here are some pointers:
- Wait until the resin thickens before applying inks—too soon, and they may sink or mix unpredictably.
- Apply white ink after every coloured drop for maximum cell formation and contrast.
- Use additives like “Resi-Blast” and “Magic Drops” sparingly to avoid over-diluting resin or affecting final hardness.
- Creates Cells and Lacing: The interaction of ink and additive is what delivers those unmistakeable concentric blooms and cells. Small adjustments to drop sequence and spacing create endlessly varying effects.
- Try mixing pastes from the Colourfun Set to blend new shade bases before starting your Petri layering.
Safe and Odourless: Many of our additives, such as “Magic Drops”, are formulated with artist safety in mind, providing a comfortable creative environment.
Finishing Touches: Bringing Your Petri Art to Life
The final result is only the beginning—whether you choose to display your Petri Dish resin as coasters, wall art, or jewellery pieces, these unique effects will turn heads. Experiment with layering, mould shapes, and colour palettes using products like the Colourfun Set and Jacquard Pinata Alcohol Ink for endless variation.
Caring for and Displaying Your Petri Dish Resin Art
Once your project has cured, you can leave it in the mould for a domed effect or remove it to showcase in frames, as coasters, or as part of larger installations. The superior colour saturation and clarity delivered by products like the Colourfun Set and Jacquard Pinata Alcohol Inks keep your results vivid for years.
Avoid strong direct sunlight or excessive heat to prevent yellowing or fading. Clean surfaces gently with a soft cloth and avoid abrasives to preserve shine.

Frequently Asked Questions
What do I need to create a Petri Dish effect in resin?
You'll need a clear epoxy resin, a set of coloured alcohol inks such as the "Petri Art" – Set of Alcohol Ink, and a white alcohol ink like "Jacquard Pinata" White Alcohol Ink. Cell effect additives such as "Resi-Blast" or "Magic Drops" are optional but recommended for dynamic effects.
When should I drop inks and additives into my resin for best results?
Allow the poured resin to become slightly viscous — typically after 20–30 minutes, depending on room temperature. This helps inks and additives form neat, defined cells rather than sinking or spreading too much.
Can I use the same alcohol inks for both Petri effects and standard ink art?
Some inks, such as the "Jacquard Pinata" White Alcohol Ink, are formulated specifically for the Petri technique and are not suitable for classic ink art painting. Always check product descriptions.
What safety precautions should I follow with alcohol inks and additives?
Always work in a well-ventilated area, wear gloves, and keep inks away from heat or flames. Avoid contact with eyes or prolonged skin exposure. Many products, like "Magic Drops", are non-toxic and odourless but always read the individual product safety notes.
What is the advantage of using cell effect additives?
Products such as "Resi-Blast" and "Magic Drops" help stimulate blooming, lacing, and dynamic movement in the resin, giving your work a one-of-a-kind, organic Petri appearance.
Can I mix different ink and additive brands or sets?
While some experimentation is possible, it's advisable to use products tested for compatibility together—like the Petri Art Set with Jacquard Pinata White Ink—for predictable results and to avoid resin issues.
How do I get more intense colours?
Use saturated pastes or inks like the Colourfun Set for your resin base, then apply vivid alcohol inks for highlights. Avoid exceeding the recommended pigment load to maintain the resin clarity.
Can the Colourfun Set be used with UV or other resin types?
Yes, the Colourfun colourants are compatible with both epoxy and UV resin, offering flexibility across many creative projects.
