5" Zigzag/Agate Round Mould

Create stunning faux-agate coasters, wall art, and decorative discs with this 5-inch Zigzag Agate Round Mould. The wavy, layered cavity mimics the natural banding of agate stone, giving your poured resin or epoxy pieces a polished, gemstone-like finish — no carving or sanding needed.

Made from flexible silicone, this mould releases cured epoxy and UV resin cleanly without tearing or sticking. At 5 inches across, it is a practical size for coasters, trinket trays, wall hangings, and home décor pieces. Suitable for beginners and experienced resin artists working with two-part epoxy or UV resin.

• 5-inch diameter — ideal size for coasters, decorative rounds, and small wall art pieces
• Zigzag agate pattern — layered wavy channels create a realistic faux-stone banding effect in every pour
• Flexible silicone construction — cured resin pops out cleanly; no release spray needed for most epoxy formulas
• Compatible with epoxy resin and UV resin — works with standard two-part epoxy (ART, 3D, casting) and UV resins
• Reusable and easy to clean — rinse with warm water after use; air dry before storing flat
• Great for pigment and alcohol ink pours — smooth cavity surface shows colour blends, cells, and lacing clearly
• Beginner-friendly — no complex prep; simply mix, pour, and demould once fully cured

How to Use

Place the mould on a flat, level surface. Mix your resin according to the manufacturer's ratio, add pigments or alcohol inks as desired, and pour slowly into the cavity. Use a toothpick or heat gun to remove bubbles. Allow to cure fully as per your resin's instructions (typically 24–48 hours for epoxy, a few minutes under a UV lamp for UV resin). Flex the mould gently to release the finished piece.

Safety Tips

Always work in a well-ventilated area when using epoxy or UV resin. Wear nitrile gloves and avoid skin contact with uncured resin. Keep resin materials away from children. UV resin requires a UV lamp or direct sunlight for full curing — do not consider it cured by appearance alone.
