Silicone molds have revolutionized candle making for beginners and professionals alike. Their flexibility, non-stick surface, and ability to capture intricate details make them the perfect choice for creating stunning, custom candles at home. If you're new to candle making and want to create beautiful shaped candles, this guide will walk you through everything you need to know about using silicone molds for candle making.
What You'll Need
- Silicone candle mold(s) of your choice
- Candle wax (soy wax, paraffin, or beeswax all work well)
- Candle wicks
- Fragrance oil (optional)
- Candle dye (optional)
- Double boiler or melting pot
- Thermometer
- Stirring utensil
- Wick holder or clothespin
Step-by-Step Instructions
- Prepare your mold and wick: Attach the wick to the bottom of your silicone mold using a small amount of melted wax. Center the wick and hold it in place with a wick holder at the top.
- Melt the wax: Use a double boiler to melt your wax slowly, stirring occasionally. Heat to the temperature recommended for your wax type (usually 175–185°F for soy wax).
- Add fragrance and dye: Once melted, remove from heat and add fragrance oil and candle dye. Stir gently to combine.
- Pour into the mold: Let the wax cool slightly (to about 140–150°F) then slowly pour into your silicone mold to avoid air bubbles.
- Let it cool: Leave in a cool, dry place for 12–24 hours depending on the size of your candle.
- Release from the mold: Gently flex the silicone mold from the edges and work your way around, then pull the candle out slowly.
- Trim the wick: Trim the wick to about 1/4 inch before your first burn.
Tips for Success
- Silicone molds don't require any release agent — the wax will pop right out once cooled
- For intricate designs, pour the wax a little slower to help it flow into all the details
- If you get air bubbles, tap the mold gently on the counter after pouring to bring them to the top
- Store silicone molds in a cool, dry place away from direct sunlight when not in use
Using silicone molds for candle making is an easy and rewarding hobby that lets you create beautiful, custom candles for your home or as gifts. With a little practice, you'll be creating stunning candles in no time!

Frequently Asked Questions (FAQ)
What is the best wax for making candles in silicone molds?
Paraffin wax is the best choice for detailed silicone molds because it shrinks slightly as it cools, making demolding easy and capturing fine details beautifully. Soy wax is the best natural option — it's eco-friendly, easy to work with, and releases cleanly from silicone. Beeswax is great for premium, long-burning candles. For beginners, soy wax is the most forgiving.
Do I need to grease a silicone candle mold before pouring?
No — silicone is naturally non-stick and candle wax releases cleanly without any release agent. Simply ensure your candle is fully cooled before attempting to demold. Using cooking spray or release agents is not recommended as they leave residue that builds up over time.
How long should I wait before removing a candle from a silicone mold?
Wait at least 12–24 hours for small to medium candles, and up to 48 hours for large candles. The candle should be completely hard and at room temperature before demolding. Rushing this step can cause the candle to warp, crack, or break during removal.
Why does my candle have a rough or uneven bottom after demolding?
This is caused by wax shrinkage during cooling, which creates a slight depression or rough surface on the top (which becomes the bottom after demolding). To fix this, do a small top-up pour once the first layer has set — pour a thin layer of wax at a slightly lower temperature to fill in the depression and create a flat base.
Can I add fragrance oil to candles made in silicone molds?
Yes! Add fragrance oil after removing the wax from heat, at around 160–170°F (71–77°C) for best scent retention. Use 6–10% fragrance oil by weight of the wax. Adding too much fragrance can affect how the wax hardens and may make demolding more difficult, so stick within the recommended range.
How do I get sharp, detailed designs from my silicone candle mold?
For the sharpest detail: use paraffin wax (it captures detail better than soy), pour at the correct temperature (not too hot), pour slowly to avoid air pockets in detailed areas, and let the candle cool completely at room temperature without moving the mold. High-quality silicone molds with mirror-finish interiors will always produce crisper detail than cheaper alternatives.
