Basic Materials for Resin Candle Holders
Resin candle holders are typically made using epoxy resin, polyester resin, or UV resin. Each resin type has unique properties that affect the manufacturing process and final product.

Epoxy Resin
Pros:
• Easy to work with, making it ideal for beginners.
• Produces a clear, glossy finish that enhances embedded decorations.
• Low odor compared to other resin types.
• Strong and durable once cured.
Cons:
• Longer curing time (usually 24–72 hours).
• Sensitive to UV light, which can cause yellowing over time without added stabilizers.
Best Uses:
Projects requiring high transparency, such as embedding flowers, glitter, or pigments.

Polyester Resin
Pros:
• More affordable than epoxy resin.
• Hard and durable, suitable for larger or outdoor pieces.
• Cures faster than epoxy resin.
Cons:
• Strong odor due to styrene content, requiring a well-ventilated workspace.
• Less transparent than epoxy resin, often appearing slightly cloudy.
• More brittle and prone to cracking under stress.
Best Uses:
Large-scale candle holders or designs that don’t require extreme clarity.

UV Resin
Pros:
• Cures quickly under a UV lamp (within minutes).
• Excellent for small, detailed projects.
• High transparency with a glossy finish.
Cons:
• Not suitable for large pieces due to limited curing depth. • Requires a UV light source for curing.
• Less durable than epoxy resin.
Best Uses:
Small or intricate candle holders, quick projects.
