ArtSil Clear Liquid Silicone

In this guide, we’ll walk through how to use ArtSil to make your own DIY silicone moulds for chocolates, candy, fondant, and more.

Why Choose Just Resin ArtSil for Food Moulds?

ArtSil is a premium, platinum-cured silicone designed for maximum detail reproduction, high tear strength, and excellent flexibility. Because it’s platinum-based, it’s safe for food contact, low in VOCs, and cures without releasing any harmful by-products. It’s also incredibly easy to use, with a simple 1:1 mix ratio by weight or volume.

Unlike cheaper tin-cured silicones, ArtSil ensures peace of mind when working with edible creations.

Materials You’ll Need

To create your own food-safe silicone moulds using Just Resin ArtSil, you’ll need:

• ArtSil Silicone – Part A & Part B (1:1 ratio)

• Digital scale or measuring containers (for accurate ratio)

• Mixing container (clean and food-safe)

• Stirring stick or spatula

• A mould box or tray (you can build one using materials like foam board, plastic containers, or wood)

• Your master object (the item you want to replicate)

• Gloves and a clean workspace

Step-by-Step Instructions

Step 1: Build Your Mould Box

Create a mould box that’s slightly larger than the item you’re casting. It needs to be sealed to prevent silicone from leaking. You can build one using household items or containers—just make sure it’s stable and watertight.

Step 2: Position the Master

Place the object you want to duplicate into the mould box. Ensure it’s secure and raised slightly from the bottom so that silicone can flow beneath it. You may wish to glue it down lightly.

Step 3: Measure and Mix ArtSil

ArtSil has a 1:1 mix ratio by weight or volume, which makes it easy to work with. Measure equal parts of Part A and Part B, then pour both into your clean mixing container.

Mix for approximately 3 minutes, scraping the sides and base of your container to ensure a fully blended mix. Proper mixing is critical to achieving a consistent cure and safe food-grade result.

Step 4: Pour Over the Master

Slowly pour the mixed ArtSil silicone into the mould box from a low height to reduce air bubbles. Start pouring into one corner and allow the silicone to flow naturally over the master.

After pouring, gently tap the sides of the mould box or lightly tap it on the table to help any trapped air escape.

Step 5: Allow to Cure

Let the mould cure undisturbed. Cure time may vary depending on ambient temperature, but most projects will fully cure within 24 hours at room temperature. Avoid moving or disturbing the mould during this time.

Step 6: Demould and Clean

Once cured, carefully remove the mould from the box and extract your master. Clean the new silicone mould with warm soapy water, rinse thoroughly, and let it dry completely before use with food.

Cleaning and Maintenance Tips

To extend the life and safety of your food-grade moulds:

• Always clean with warm water and mild detergent after each use.

• Avoid abrasive tools or cleaners that can damage the silicone surface.

• Store moulds in a cool, dry place away from direct sunlight.

• Do not cross-contaminate: if a mould has been used for resin, do not reuse it for food.

Retire any moulds that show signs of wear, residue build-up, or surface degradation.
