4" Heart Mould

The 4-inch Heart Mould from Shrebhavi is a sturdy silicone mould designed for casting epoxy resin, UV resin, plaster, wax, and soap. At 4 inches across, it produces a generously sized heart that works beautifully as a decorative piece, personalised gift, tray, or coaster base — ideal for hobbyists and small resin businesses alike.

Made from flexible food-grade silicone, the mould releases cured resin cleanly without cracking or tearing, giving you a smooth, glossy surface straight out of the mould. Whether you are embedding dried flowers, glitter, or pigment swirls, the deep heart cavity gives you enough room to create layered, detailed pours every time.

• 4-inch size: Large enough for statement pieces, gifts, and decorative hearts without being oversized.
• Flexible silicone build: Demoulds cleanly — simply peel back the sides and pop out your cured piece without damage.
• Smooth interior finish: Produces a high-gloss surface on epoxy and UV resin casts with minimal sanding needed.
• Multi-material compatible: Works with epoxy resin, UV resin, plaster, wax, soap, and air-dry clay.
• Reusable and durable: Silicone withstands repeated pours and resists staining from pigments and dyes.
• Easy to clean: Rinse with warm water after use; fully cured resin peels off without residue.
• Great for gifting projects: Perfect for personalised resin hearts, preserved flower keepsakes, and festive craft projects.

How to Use

Lightly spray the mould with a mould-release agent for best results. Mix your epoxy resin as per the manufacturer's ratio, pour slowly to avoid air bubbles, and allow to cure fully before demoulding. For UV resin, cure under a UV lamp in layers if the pour is deep.

Safety Tips

Always wear nitrile gloves and work in a well-ventilated area when handling uncured epoxy or UV resin. Keep resin materials away from children. Do not use this mould for food preparation after it has been used with resin or chemical-based materials.
