See how it works!
In this video, we show you step by step how to make your own candle molds and pour beautiful candles:
Why make your own candle molds?
With your own candle molds, you have complete creative freedom. Think about:
Unique shapes: From classic Christmas trees and stars to modern geometric designs
Perfect size: Just the right height for your candlestick or Advent wreath
Reusable: Once you've made a good mold, you can keep pouring candles endlessly.
Cost-effective: Especially if you want to make multiple candles or give them as gifts
Durable: High-quality silicone molds last for years
From idea to candle mold: the possibilities
1. Start with a 3D print
Just like in our 3D print to mold tutorial , you can start with a 3D printed model. This is ideal for:
Complex geometric candles
Personalized designs with names or dates
Exact replicas of existing objects
Modern, sleek shapes
Tip: Consider the release angle when designing! Candles should be easy to remove from the mold. Avoid undercuts and choose slightly conical shapes.
2. Use existing objects as master
Don't have a 3D printer? No problem! You can also make molds from:
Beautiful vintage candles that you will want to duplicate
Decorative objects (think small figurines, pine cones, or Christmas ornaments)
Homemade clay models
Wooden or plastic shapes
3. Manual shaping
For simple shapes you can also cast directly into a mold box around a simple model or even create an empty space with partitions.
Step by step: making your first candle mold
Step 1: Choose the right silicone
For candle molds we recommend a silicone with these properties:
Shore Hardness A20-A30: Flexible enough to get the candle out, firm enough to keep its shape
Heat resistant: Candle wax can withstand temperatures up to 80-90°C, choose silicone that can withstand at least 200°C
Good detail reproduction: For sharp edges and fine details
Low shrinkage: So that your mold is exactly the right size
Step 2: Prepare your master's degree
Make sure your model is completely smooth and clean. For 3D prints, this means:
Sand with fine sandpaper (start coarse, finish with 400-600 grit)
If necessary, apply a coating for extra smoothness
Degrease thoroughly with alcohol or soapy water
Step 3: Build your mold box
Create a box around your model with at least 5-10mm of space on all sides. You can use:
LEGO blocks (super handy and reusable!)
Cardboard or foam board
Wooden planks
Special mold boxes
Don't forget: Seal all seams well with caulk or clay, otherwise your silicone will leak out!
Step 4: Mix and pour the silicone
Always follow the instructions for your specific silicone, but in general:
Weigh component A and B accurately (usually 1:1 or 10:1 ratio)
Mix thoroughly for 2-3 minutes
Vent in a vacuum chamber (optional but recommended)
Pour slowly in a thin stream from a corner
Let the silicone fill the mold itself and expel air bubbles
Gently tap the box to remove any last air bubbles
Step 5: Curing and demoulding
Let your mold cure for at least 24 hours (check the specifications of your silicone). Then carefully remove the box and pull out your master. Your mold is now ready to use!
Candle casting: from mold to magical light
Candle Pouring Supplies
Your silicone mold
Candle wax (paraffin, soy, beeswax, or a mix)
Wick (choose the correct thickness for your candle diameter)
Fragrances (optional – think cinnamon, orange, pine for Christmas!)
Food coloring (optional)
Double boiler or wax melter
Thermometer
Wick holder or skewer
The casting process
Prepare the wick: Place the wick in the center of your mold. Use a wick holder or tie the wick to a skewer placed over the mold.
Melt the wax: Heat your wax to the recommended temperature (usually 70-85°C, check your wax type)
Add fragrance and color: Do this at the correct temperature according to the instructions of your additives
Pour the wax: Pour slowly into the mold, leaving the wick in place
Let cool: Wax shrinks as it cools, so you may need to add more later
Demolding: After complete cooling (a few hours), you can carefully remove the candle from the flexible silicone mold.
Tips for perfect Christmas candles
Temperature is key: Pouring too hot will create air bubbles, pouring too cold will create a rough surface.
Lightly spray your mold: A very thin layer of cooking oil or special release spray can help, but use sparingly!
Experiment with layers: Pour different colors in layers for a beautiful effect
Add decorations: Dried flowers, glitter, or herbs can be beautiful (note fire safety!)
Trim the wick: Leave 5-10mm protruding for optimal burning
Creative ideas for Christmas candles
Classic and cozy
Christmas tree candles in different sizes for a mini forest
Star-shaped candles for the windowsill
Traditional pillar candles with Christmas scents
Modern and stylish
Geometric shapes in winter colours
Minimalist cylinders with a subtle scent
Sculptural designs as decorative objects
Personal and unique
Candles with initials or year
Replicas of special objects
Candles in the shape of pets or hobbies
Common problems and solutions
Air bubbles in the candle
Cause: Poured too hot or poured too quickly Solution: Pour at a lower temperature and tap the mold gently while pouring.
Candle stays in the mold
Cause: Mold too stiff or undercuts in the design Solution: Use softer silicone (lower Shore hardness) or adjust your design
Irregular surface
Cause: Poured too cold or mold not clean Solution: Increase casting temperature and clean mold thoroughly between castings
Fuse is not straight
Cause: Fuse not properly fixed Solution: Use a wick holder or tie the wick tightly to a stick
Safety and maintenance
Working safely with wax
Never heat wax directly on the fire, always use a double boiler
Keep a thermometer handy
Work in a well-ventilated area
Keep water away from hot wax
Have a fire extinguisher or fire blanket on hand
Maintaining your silicone molds
Clean molds with warm water and soap after use
Dry thoroughly before storage
Store out of direct sunlight
Avoid sharp objects that could damage the mold
With proper care, silicone molds last for years!
