💡 Quick Tips:
🎯 A Simple Example: Making Your First 3-inch Soy Candle
You've just bought a beautiful 3-inch glass jar and want to make a soy candle. Which wick do you need? Let's find out:
Just do this:
1️⃣ Click the "3" Pillar" preset button (or enter 3 in the diameter field)
2️⃣ Make sure "Soy Wax" is selected in the dropdown
3️⃣ The tool recommends: ECO-6 wick
4️⃣ Order ECO-6 wicks and do a test burn before making more candles
5️⃣ Watch the SVG—the flame size changes with your wick selection! 🕯️
Pro tip: If your test candle tunnels (burns down the middle), go up one wick size. If it produces soot or flames too high, go down one size.
⚠️ Safety First: Never Leave Candles Unattended
Always burn candles on a heat-resistant surface away from drafts, flammable materials, children, and pets. Never leave a burning candle unattended. Extinguish candles before leaving a room or going to sleep.

The Historical Problem: Before modern wick science, candle makers relied purely on trial and error. Medieval chandlers would test dozens of different cotton threads and braids, watching candles tunnel, smoke, or drip wax everywhere. The problem? They didn't understand capillary action—the physical force that pulls liquid wax up through the wick's fibers to feed the flame. Too small a wick, and the flame drowns in its own wax pool. Too large, and you get a smoky inferno.
The Scientific Discovery: In the 1800s, scientists studying fluid dynamics discovered that capillary action depends on surface tension and fiber diameter. The narrower the spaces between fibers, the higher the liquid climbs (like water in a narrow straw). This led to standardized wick construction: cotton cored (CD series), flat braided (ECO series), and square braided (LX series). Each design controls how much wax flows to the flame based on candle diameter and wax viscosity.
Modern Application: Today's candle makers match wick series to wax type and diameter using burn testing data. Soy wax (lower melting point) needs a slightly larger wick than paraffin (higher melting point) for the same diameter. Palm wax, with its unique crystalline structure, requires careful wick selection for optimal burn. The "perfect burn" creates a wax pool that reaches the container edge within 2-4 hours—no tunneling, no waste, no soot.
The Magic Moment: You light your handmade candle, and instead of watching it tunnel or smoke, the flame burns steady and clean. The wax pool spreads perfectly to the edges. The room fills with fragrance, not soot. That's the moment capillary action becomes real—when 200 years of wick science turns your craft into something beautiful and functional. Science wins again! 🕯️
🐾 From the Lab Cat's Perspective:
Humans invented "wick sizing" when the solution was obvious: watch the flame. If it's too big, I knock the candle over. If it's too small, I ignore it. I've been regulating candle safety for centuries through strategic paw intervention. You're welcome for my service! 😸
