If you’re into stylish home décor or a candle-making enthusiast, you’ve probably seen bubble candles popping up all over Instagram and Pinterest. These trendy geometric candles have become a firm favourite for their aesthetic charm and minimalist vibe - but did you know they're surprisingly easy to make at home?
In this step-by-step guide, we’re going to show you how to make bubble candles from scratch, using quality materials and creative techniques. Whether you're crafting for yourself, for gifts, or as part of a small business venture, this blog will walk you through the entire process.
Let’s dive into how to make bubble candles - and why they’re one of the most satisfying (and stylish) DIYs around.
What Are Bubble Candles?
Before we explain how to make bubble candles, let’s talk about what they are.
Bubble candles are cube-shaped candles made up of symmetrical bubble-like orbs. Typically made from soy wax or a natural wax blend, they can be coloured and fragranced to suit your vibe. These candles are both decorative and functional - perfect for minimalist interiors or as statement pieces for events and gifts.
You’ll often find them unscented for visual display, but adding fragrance oil can turn them into multi-sensory delights!
Materials You'll Need
If you're learning how to make bubble candles for the first time, you don’t need loads of fancy equipment. Here’s what you’ll need to get started:
Equipment & Supplies:
Bubble candle silicone mould (readily available online)
Wax (soy wax, rapeseed wax, or a natural wax blend)
Fragrance oil (optional but highly recommended)
Candle dye or liquid colourant (optional for colour)
Wicks (pre-tabbed cotton wicks work well)
Wick holder or skewer
Pouring jug or heat-safe container
Double boiler or microwave-safe jug
Thermometer
Scissors
Step-by-Step: How To Make Bubble Candles
Now that you’ve got your materials ready, let’s walk through the process of how to make bubble candles from start to finish.
Step 1: Measure Your Wax
Start by measuring the right amount of wax for your bubble mould. A standard bubble candle mould typically takes about 120g to 140g of wax, depending on size. It’s a good idea to weigh your wax using digital kitchen scales for accuracy.
Step 2: Melt the Wax
Using a double boiler or microwave, slowly melt the wax. If you’re using the microwave, melt in short 30-second bursts and stir regularly. For a double boiler, gently heat the wax until it’s fully melted and reaches around 70–75°C.
Step 3: Add Fragrance Oil
Once your wax is melted, allow it to cool slightly to around 60–65°C before adding your fragrance oil. The usage rate is usually 6–10%, but always check your wax manufacturer’s guidelines.
For example:
If you're using 120g of wax and want a 10% scent load, use 12g of fragrance oil.
Stir the mixture gently but thoroughly for 1–2 minutes to ensure even distribution of the scent.
Step 4: Add Colour (Optional)
If you want to add colour, now’s the time! Add a few drops of liquid candle dye or a small amount of dye chips and stir until evenly blended. Pastel tones and neutral shades are popular for bubble candles, but you can go bold too!
Step 5: Prepare the Mould
Thread the wick through the centre hole in the mould. Use a wick holder or tie the wick around a skewer across the top to keep it centred and taut. Make sure the wick is secure and straight before you pour.
Tip: If your silicone mould doesn’t have a pre-made hole, use a hot needle or skewer to create one and seal the bottom with a bit of Blu Tack or mould sealer to prevent leaks.
Step 6: Pour the Wax
Slowly pour the scented wax into the mould, being careful not to create air bubbles. Pour steadily until the mould is full, then give it a gentle tap on the counter to release any hidden air pockets.
Let the candle cool and harden completely - this can take 4 to 6 hours, depending on your room temperature.
Step 7: Remove the Candle
Once fully set, carefully remove the candle from the silicone mould. This is the fun bit - you’ll see your bubble candle come to life with all its geometric charm!
Trim the wick to about 0.5–1cm and you're done.
Tips for Perfect Bubble Candles
Now that you know how to make bubble candles, here are a few tips to ensure a smooth, professional finish:
Use a thermometer to get your pour temperature right — it helps avoid sinkholes and uneven finishes.
Tap your mould gently after pouring to remove air bubbles.
Experiment with layering colours for a two-tone or ombre effect.
Test different fragrance oils to find your signature scent — florals, spa scents, and fruity blends are especially popular for home décor candles.
Store in a cool, dry place away from sunlight to avoid colour fading or sweating.
Are Bubble Candles Just for Display?
While bubble candles are often used as decorative pieces, they can be burned like any other candle - just remember they may burn unevenly due to their shape.
If you’re making bubble candles to sell or gift, always include a burning safety label and instructions. These should advise the user to place the candle on a heat-resistant dish or tray, never leave it unattended, and trim the wick before each use.
Remember that you will also need 10% CLP labels in order to be legally complaint in the UK.
Why Are Bubble Candles So Popular?
Bubble candles combine the soothing glow of candlelight with eye-catching design. Their chunky geometric look fits perfectly with modern, minimalist, and even boho interiors. Plus, they're ideal for flat-lay photography, gift boxes, and influencer aesthetics.
When paired with high-quality fragrance oil, bubble candles don’t just look good - they smell incredible too, elevating any room with minimal effort.
Can You Sell Bubble Candles?
Yes, absolutely — as long as you follow UK candle regulations (such as CLP labelling for scented products), bubble candles are a great product to add to your range. They’re popular on Etsy, craft markets, and online boutiques because of their uniqueness and visual appeal.
✅ Pro tip: Offering them in seasonal colours or scent collections can help boost sales!
