Compatible Materials

Epoxy Resin

Mix Part A and Part B epoxy resin at a 3:1 ratio by volume. Stir slowly for 3–5 minutes and pour into the mold. Epoxy resin cures in 24–48 hours at room temperature, producing the clearest, most durable round agate coasters with a glass-smooth finish that requires no sanding or polishing.

UV Resin

Single-component UV resin cures under a 36W+ UV lamp in 2–5 minutes. Pour in maximum 3–4mm layers to prevent heat-cracking. Wipe the surface with IPA after each cured layer to remove the oxygen inhibition layer before adding the next pour or surface details.

Soy Wax and Paraffin Wax

Pour soy wax at 50–55°C and paraffin wax at 60–65°C for round wax discs, wax melts, and decorative candle tops. Add fragrance oil at 6–10% by weight of wax for scented pieces. The round shape produces the most popular size of wax melt disc.

Cold-Process Soap and Plaster

No mold release spray needed for cold-process soap on platinum silicone — demold after 24–48 hours and cure 4–6 weeks. For plaster, a light spritz of mold release spray eases demolding of the finished disc.

How to Create Round Agate-Effect Resin Coasters

Step 1 – Prepare Your Workspace

Set up on a silicone mat or parchment-covered flat surface. Gather epoxy resin, 2–4 colours of alcohol inks or resin pigments, a heat gun for bubble removal, mixing cups, stir sticks, gloves, and safety glasses.

Step 2 – Mix and Tint Your Resin

Measure Part A and Part B epoxy at a 3:1 ratio by volume. Mix slowly for 3–5 minutes. Divide into separate cups and add your colours. Classic agate palettes: white + grey + black (monochrome), teal + white + gold (aqua agate), blush + rose gold + ivory (rose agate), indigo + silver + white (midnight agate).

Step 3 – Pour and Swirl

Pour the base colour into the mold first, then add the second and third colours in bands or swirls. Use a toothpick or skewer to drag through the colours in long, flowing curves — mimicking the organic banding of natural agate stone. The circular mold's shape naturally enhances the swirling motion, creating more dynamic, concentric patterns than a square mold.

Step 4 – Add a Geode Vein or Botanicals

Brush a fine gold or silver metallic vein through the agate bands for a geode effect. Add pressed dried flowers or biodegradable glitter between layers for botanical or celestial agate styles.

Step 5 – Pop Bubbles and Cure

Pass a heat gun 10–15cm above the surface to pop bubbles. Cover loosely with a box and cure on a level surface for 24–48 hours without moving the mold. Above 18°C ambient temperature gives the best results.

Step 6 – Demold and Finish

Gently flex the silicone mold around the edges and peel back to release the round agate piece. The easy release platinum silicone leaves a naturally glossy finish on the cast surface. Lightly sand the back with 400-grit paper for a flat, non-scratching base on the finished coaster.

Frequently Asked Questions

What's the difference between the circle and square agate mold?

Shape and style: the circle mold creates the classic, universally loved round coaster that fits all drinks and works beautifully for ring dishes and wax melts. The square mold creates a more modern, geometric aesthetic suited for grid wall art and square desk accessories. Many artists buy both and combine them in matching agate sets for versatile product offerings.

How do I get the agate banding effect in a circle mold?

Pour your base colour first, then add 2–3 additional colours in rings or arcs. Drag a toothpick from the centre outward in a starburst pattern, or in sweeping curves, to create natural agate banding. The circular shape naturally encourages concentric patterns that closely mimic real agate stone.

Do I need a mold release spray?

No — platinum silicone has natural easy release properties. Cured resin pops out with a gentle flex of the mold. A light spray of silicone mold release spray can be used if you notice sticking after many uses, but is not required.

Can I add glitter or pressed flowers to this mold?

Yes — add glitter between resin layers or use the partial-gel technique for pressed dried flowers. Pour a 2–3mm base, let it partially gel for 20–30 minutes until thick but not set, place botanicals, then pour the final layer.

How do I prevent bubbles?

Mix resin slowly (not vigorously) to minimise air entrapment. After pouring, use a heat gun or lighter 10–15cm above the surface to pop surface bubbles. Warming your resin cups in warm water before mixing also reduces bubble formation.

How many uses can I expect?

With proper care — hand-wash with mild soap, avoid acetone, store flat away from direct sunlight — this platinum silicone mold is rated for 100+ uses.

Is there a 4-inch square version of this mold?

Yes — see our 4 Inch Agate Square Mold for the square version. Combine both for a mixed-shape coaster set that offers more variety to buyers at craft fairs.

What is the return policy?
