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:

1. 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).
2. 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.
3. 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.
4. 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.
5. Customise your base colours with the “Colourfun Set” for unique tones beneath the Petri blooms.
6. 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.

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.
