Zincore Wick for Gel Wax

Why Every Gel Candle Maker in India Is Talking About Zinc Core Wicks If you’ve been making gel wax candles in India, you know the struggle — finding the right wick is one of the most frustrating parts of the craft. Cotton wicks mushroom. Paper core wicks collapse. And until now, the best option — the zinc core wick — was nearly impossible to source within India. That changes today. Kaari Candle Supplies is proud to be one of the first candle supply brands in India to bring authentic zinc core wicks to Indian candle makers — hobbyists, small batch crafters, and professional candle businesses alike. The zinc core wick isn’t just a wick — it’s the backbone of a perfect gel candle. It stands straight, burns clean, and holds its form through every pour. In this guide, we’ll cover everything you need to know: what zinc core wicks are, why they’re the best wick for gel wax candles, how to use them, and why Kaari is your go-to source to buy zinc core wicks in India. What Is a Zinc Core Wick? A zinc core wick is a candle wick that has a thin zinc metal wire running through its center, surrounded by a braided cotton or cotton-blend outer layer. The zinc core acts as a rigid spine, giving the wick structure and stability — especially critical in liquid or semi-liquid waxes like gel wax. Rigid Structure The zinc spine keeps the wick perfectly upright during pouring and burning — no drooping, no leaning. Controlled Burn Zinc core wicks produce a steady, moderate flame that melts gel wax evenly without overheating. Clear Gel Clarity Produces minimal soot and mushrooming, keeping your beautiful gel candle crystal clear. Clear Gel Clarity Ideal for container candles, jar candles, and all gel wax applications. Pre-tabbed options available. The braided outer layer is typically made from 100% natural cotton, which ensures a clean, non-toxic burn. The zinc core provides the rigidity without affecting the burn quality — zinc itself does not burn; only the cotton burns as the candle melts. Why Zinc Core Wicks Are the Best Choice for Gel Wax Candles Gel wax is unique. It’s transparent, pourable like a liquid when melted, and has a higher oil content than traditional paraffin or soy wax. This creates very specific challenges for wicks: Challenge 1 — The wick must stay upright in liquid gel Gel wax has a very low viscosity when melted. A cotton-only or paper core wick will simply fall over or float away during the pour. The zinc core’s rigid spine acts like a reinforcing rod — it keeps the wick perfectly centered and vertical throughout the entire candle-making process. Challenge 2 — Gel wax requires a wick that burns hotter Gel wax has a higher density than soy or paraffin, requiring a wick that can sustain a slightly hotter flame to achieve a full melt pool. Zinc core wicks are designed to burn with a consistent, moderately hot flame, making them ideal for gel wax candle making. Challenge 3 — Maintaining the visual clarity of gel candles The whole appeal of a gel candle is its crystal clear appearance — often with embedded decorations, sea shells, pebbles, or botanicals. A wick that produces excessive soot or mushrooming will cloud your gel wax. Zinc core wicks, when properly sized, produce a clean flame and minimal carbon buildup. Pro Tip from Kaari: Always trim your zinc core wick to approximately 6mm (¼ inch) before each burn. This ensures the cleanest flame and prevents any soot from clouding your gel candle. How to Use Zinc Core Wicks in Gel Candles — Step by Step New to zinc core wicks? Here’s a simple, beginner-friendly guide to using them in your gel wax candle making process: 1) Choose the right wick size Wick sizing depends on your container diameter. As a general rule: use a smaller zinc core wick size for containers under 5cm, a medium size for 5–8cm, and a larger size for wider containers. Kaari provides a sizing guide with every order. 2) Secure the wick with a wick sticker or tab Most zinc core wicks from Kaari come pre-tabbed with a metal sustainer. Press the metal tab firmly to the center of your glass jar or container using a wick sticker or a small drop of hot glue. 3) Keep the wick centered using a wick bar or clothespin Lay a wick bar, clothespin, or chopstick across the top of your container to hold the wick perfectly centered while you pour your melted gel wax. 4) Pour gel wax slowly at the correct temperature Melt your gel wax and let it cool to around 80–85°C before pouring. Pour slowly to prevent bubbles. The zinc core will hold perfectly in place even as the liquid gel surrounds it. 5) Let the candle cool completely before trimming Allow the gel candle to set at room temperature for at least 4–6 hours. Once fully set, trim the zinc core wick to 6mm before the first burn.   Frequently Asked Questions About Zinc Core Wicks in India   1) Where can I buy zinc core wicks in India? Zinc core wicks are now available in India exclusively at Kaari Candle Supplies. You can order online and get delivery across globally. Previously, candle makers had to import zinc core wicks from the US or Europe, which was expensive and time-consuming. Kaari has solved that problem for the Indian candle making community.   2) Are zinc core wicks safe for gel wax candles? Yes, zinc core wicks are completely safe and are the industry-standard choice for gel wax candles worldwide. The zinc metal in the core does not burn — only the outer cotton braid burns. Zinc core wicks have been tested and approved for use in candle making by international candle safety standards. 3) What size zinc core wick should I use for my gel candle? Wick sizing depends on your container diameter. For containers up to 5cm wide, a small to medium zinc core wick works well. For 5–8cm containers, use a medium wick. For anything wider, a large zinc core wick is recommended. Always conduct a burn test before finalizing your wick size. Kaari provides a free wick size guide with all orders. 4) Can I use zinc core wicks in paraffin or soy wax? Zinc core wicks can technically be used in paraffin wax container candles as well. However, they are specifically designed and optimized for gel wax. For soy wax, cotton core or CD wicks are generally a better choice. For gel wax, zinc core is the undisputed best option. 5) How do I know if my zinc core wick is the right size? A properly sized zinc core wick should produce a flame that creates a full melt pool reaching the edges of your container within 2–3 hours of burning. The flame should be approximately 1.5–2cm tall. If the flame is too small and doesn’t reach a full melt pool, size up. If the flame is too large or produces soot, size down. Always trim the wick to 6mm before each burn test. 6)Does Kaari Candle Supplies ship zinc core wicks across India? Yes!
