Complete Benefits of Making Large Candles Without Air Bubbles

Zero Waste Candle

Large candles make stunning decorative statements in any space when their wax forms flawless cohesive masses absent ugly defects like pits or bubbles. But achieving smooth and crater-less results poses one of candle making’s greatest challenges even among seasoned makers.

This comprehensive guide breaks down the fundamentals behind the frustrating air pocket phenomenon plus shares pro techniques for pouring perfect hollow candles every time. Read on to learn specialized drips, controlled cooling tricks, troubleshooting, and final embellishment touches to create customized conversation-starting candles.

Understanding Candlemaking Basics

Before exploring targeted solutions for large candles perfection, first understand wax and wick fundamentals. Candlewax, usually paraffin or soy, melts when heated, binds to wick fibers then solidifies around strands to form fuel “pools” once lit. Wicks act like tiny straws, drawing liquefied wax upward via capillary action to feed flames.

More advanced blends incorporate special additives to influence burn properties. As melted wax travels skyward and then cools down, air bubbles sometimes get trapped, disfiguring finished looks. Mastering fluid dynamics, temperature regulation and setup logistics helps reduce flaws.

Necessary Supplies and Tools

Compiling quality ingredients and accessories enables flawless execution:

  • Wax – Paraffin or soy wax blocks generate the clearest results
  • Wicks – Pre-tabbed wicks with reinforced bottoms prevent snags
  • Dyes + Scents – Use extras like liquid colors or essential oils for customization
  • Molds – Opt for thicker silicone molds that won’t split when filled
  • Double Boiler – Even indirect heat prevents burning wax
  • Thermometer – Monitor wax temperature between 185°F – 200°F
  • Spoon – Long-handled spoon for stirring wax
  • Pouring Pitcher – Controlled pouring with a spouted pitcher
  • Workspace Preparation

Before illuminating wicks, prep spaces for success through organization and risk reduction:

  • Clear counters from clutter providing room for supplies
  • Cover surfaces surrounding the work area to prevent damage
  • Turn off overhead ventilation fans to limit air disturbance
  • Pull back curtains, and disable ceiling fans – draftiness encourages bubbles
  • Fill cleaning supplies on standby for spills like paper towels
  • Don protective equipment like gloves and safety goggles
  • Wax Selection and Prep

Large candles project demand wax types with higher melting points to resist slumping under their weight when scaling up in size. Opt for hard, contracted paraffin or soy blends. Softer waxes like gel or vegetable-based struggle to support wick structures as breadth widens.

Always chop wax blocks into smaller chunks before melting to quicken liquefying. Beam chunks into vessels then place over a simmering water bath, stirring periodically. When melted, add coloring or scents when the mixture hits 185°F. Let cool down to 175°F-180°F before pouring.

Wicks and Their Placement

Wicks establish vertical foundations for rising wax layers and fuel melt pools when lit. But positioning strands improperly throws off delicate fluid distribution dynamics and airflow, causing bubbles or tunneling over time. Here are wick installation best practices:

Center Wick Tabs – Before pouring, securely adhere wick tab bases centered inside container bottoms using drops of hot glue. Centering prevents wall favoritism.

Space Multiple Wicks – For very wide vessels over 6 inches across, install multiple wicks spaced evenly apart to encourage even wax melt distribution rather than isolated pooling.

Thread Wick Ends – Pull the wick ends up through smaller hole punctures poked near the top rim, then knot strands if using free-floating methods. Knotting prevents wicks from slipping down while burning.

 Set Wick Height – Carefully determine wick heights that prevent excess smoke while fully melting wax across. As a starting guide, leave 11⁄2 to 2 inches of extra wick exposed above jar rims. The wider the large candles, the taller wicks should be installed.

Pouring Procedures

Carefully implement these pouring best practices to minimize bubbles:

Tip and Tilt Containers – Gently angle and rotate vessels during pouring to coat sides. Tilting prevents wax from dropping directly down, creating splatter and bubbles. Slowly tip one edge near the pouring spout lower. This lets wax adhere and creep up vertical walls.

Pour in Corners – Direct thin pouring streams into interior corners, allowing the wax to climb upwards. Corners give wax an edge to grab and pull itself vertically rather than mounding bubbles on a flat bottom.

Start and Stop Pour – Alternate quickly pouring then completely stopping the flow. Sudden starts essentially inject wax underneath itself, while abrupt halts prevent overflow accumulation. Start-stop pouring also disrupts surface tension.

Circle the Spout – Continuously rotate and angle the pouring spout in a small circular pattern. This agitates and detaches bubbles clinging to the sides while circulating fresh wax everywhere.

Maintain Reservoirs – Always leave the remainder of unused wax in pouring vessels instead of emptying them. Reservoirs allow re-circulation by scooping back up and repouring the last vestiges of unused wax.

Poke Walls Pre-Finish – When containers nearly fill, pause pouring. Use a skinny skewer to poke vertical walls releasing any adhered bubbles before topping off. This intervention preempts air gaps from becoming permanently trapped.

Managing Cool Down and Smoothing

As poured wax transitions from liquid to solid, molecules constrict to occupy less volume. Simultaneously, densities increase cascading downwards while excess air pockets float upwards. Strategic cooling interventions ensure bubbles surface and then dissipate instead of becoming engulfed:

  • Periodically wipe bubbles away with a narrow curved tool
  • Gently perturb setting wax using Figure 8 motions to dislodge air gap buildup
  • Avoid sudden drafts by shielding projects with surrounding panels
  • When nearly hardened, spread an overlapping layer of fresh wax overtop to fill divots then smooth

Troubleshooting Bubble Issues

Despite preventative steps, bubbles still sometimes happen! But all is not lost, as various remedies can salvage large candles with sunken spots, pits, or surface craters. Here are specific troubleshooting large candles techniques:

Warm Problem Areas – Bubbles create divots because they prevent wax from fully reaching certain points. Reheat affected areas using a specialized heat gun which allows precise targeting and avoids over-melting surrounding regions. Next, smooth a warmed pallet knife across impaired zones, essentially filling holes as wax becomes workable again. The warmer blade will re-melt wax upon contact, allowing it to reflow into gaps.

Pierce Bubbles – Air trapped below hardened wax surfaces causes pitted textures. Insert an awl, ice pick, or other slender instrument at an angle into problem bubbles to carefully pierce. Puncturing releases compressed air so the wax can then settle into cracks. Cool and harden candles once again following this fix.

Sand Away Imperfections – Small pockmarks invisible from afar remain eyesores up close. Once large candles fully cure and cool, gently buff surfaces using a fine grit sanding sponge to evenly abrade peaks down into craters. This levels waxy terrains without removing large quantities. Always sand softly and avoid rubbing through exterior coats.

Highlight Cracks Creatively – Alternatively, retain character lines, fractures, and divots by accenting them as intentional features. Use metallic enamel paints to highlight deep grooves with glistening color. Or, press ultra-fine glitter grains into fissures for added visual intrigue. Lean into the undertones of ruin and entropy.

Troubleshooting Common candle-making Issues

how to make large candles

Tunneling Candles:

  • Cause – Wicks are too small for wax pillar/jar, causing rapid melting and tunnel formation
  • Fix – Use a larger wick or trim wick height to 1⁄4 inch before burning

Soot Build Up:

  • Cause – Wick is too large for the wax pool, creating excess smoke and carbon buildup
  • Fix – Trim the wick or switch to a smaller wick size

Weak Scent Throw:

  • Cause – Too little fragrance oil used for the wax amount
  • Fix – Increase fragrance oil percentage to 10-15% of wax volume

Wax Not Melting Properly:

  • Cause – Wax poured at too low of a temperature
  • Fix – Increase pouring temp to 185°F; preheat candle vessel

Applying Finishing Touches and Embellishments

Finally, complete candles by adding back dust cover, bespoke labels, or decorations:

  • Affix fabric over exteriors using Mod Podge then finish raw edges with rope
  • Print personalized logos or inspirational quotes directly onto adhesive paper wraps
  • Roll base coats in granules like fine glitter or crushed seashells for tactile intrigue
  • Impress buttons, charms, or dried botanicals directly into pliable exterior layers
