Why Silicone for Candle Molds?
Silicone is the ideal material for candle molds because:
Heat resistance - Resistant to molten wax up to 200°C
Flexibility - Easily deformable for complex designs
Non-stick coating - Candles release effortlessly without release agent
Detail Rendering - Reproduces finest details and textures
Sustainability - Hundreds of candles per mold possible
No shrinkage - Dimensionally stable for consistent results
Recommended Silicone for Candle Casting
RTV Silicone (Room Temperature Vulcanizing)
Platinum-catalyzed RTV silicone is the best choice for candle molds:
Shore A 10-20 - Soft, flexible silicone for complex shapes and undercuts
Shore A 25-30 - Versatile hardness for most candle designs
Shore A 40-50 - Stronger molds for large candles and production
Polytek Silicone for Candles
Polytek TinSil Series - Tin-catalyzed, economical for large molds
Polytek PlatSil series - Platinum-catalyzed for superior quality
Polytek PolyGel - Gel silicone for brush molds
Wacker and CHT Silicones
Wacker Elastosil M - Professional quality for production
CHT Silicones - Reliable performance for craftsmen
How to Make a Silicone Candle Mold?
Method 1: Block Mold
The most commonly used method for candle molds:
Preparation - Place your master model in a leak-proof container or build a mold box
Attachment - Glue the model to the base with hot glue or clay
Distance - Allow at least 10-15mm of silicone around the model
Mixing - Mix silicone A and B components in the correct ratio (usually 1:1 or 10:1)
Bleeding - Remove air bubbles with vacuum chamber (optional but recommended)
Pouring - Pour slowly from one point, let silicone flow itself
Curing - Allow to cure for 16-24 hours at room temperature
Demolding - Remove the mold and cut a casting opening if necessary
Method 2: Brush-On Mold
Ideal for large or complex objects:
Preparation - Clean and dry the master model
Release agent - Apply a release agent if necessary
First Layer - Brush a thin layer of silicone over the model
Reinforce - Add fiberglass or cotton cloth for strength
Build up - Apply 3-5 coats to a thickness of 5-10mm
Mother mold - Make a support mold from plaster or plastic
Method 3: Two-Part Mold
For complex candles without undercuts:
Parting Plane - Determine where the mold should split
First Half - Cover half of the model with clay
Registration Points - Make depressions in the clay for alignment
First Pour - Pour the first half of the mold
Release - Apply release agent to cured silicone
Second pour - Remove clay and pour second half
Tips for Perfect Candle Molds
Wick Hole - Add a channel for the candle wick
Pouring Opening - Make it large enough for easy pouring
Venting - Add small channels to allow air to escape
Wall thickness - Minimum 10mm for stability
Support Mold - Use a master mold for large flexible molds
Temperature - Work at 20-25°C for optimal results
Applications
Decorative candles and sculptures
Pillar and table candles
Scented candle production
Soy and beeswax candles
Paraffin and gel candles
Wax melts and tealights
Soap and bath products (with suitable silicone)
Frequently Asked Questions
Do I need a release agent? Not for most platinum silicones, but it can help with tin silicones.
How many candles can I make? A good silicone mold will last for 200-500+ candles, depending on use and care.
Which hardness is best? Shore A 25-30 is ideal for most applications, softer for complex shapes.
