<p><strong>Yes.</strong> Every piece of glass we use has passed rigorous third-party safety testing to ensure it can safely withstand the heat of a burning candle.</p><h2 id="astm-safety-standards">ASTM Safety Standards</h2><p>All Greenleaf glassware is tested and certified by the <a href="https://www.astm.org/">American Society for Testing and Materials (ASTM)</a>, an independent organization that sets safety standards for materials and products across industries.</p><p>ASTM testing for candle containers includes:</p><p><strong>Thermal shock resistance:</strong> The glass must withstand sudden temperature changes without cracking or shattering.</p><p><strong>Heat resistance:</strong> The glass must safely contain the heat generated by a burning candle without weakening.</p><p><strong>Structural integrity:</strong> The glass must maintain its strength throughout the product&apos;s lifecycle.</p><p>This third-party testing ensures that when you use your Greenleaf candle according to care instructions, the container will perform safely from first light to last burn.</p><h2 id="why-glass-quality-matters">Why Glass Quality Matters</h2><p>Not all glass is created equal. Candle containers need to handle:</p><ul><li>Direct flame heat from the wick</li><li>Hot liquid wax pooling at the bottom</li><li>Temperature fluctuations as the candle burns and cools</li><li>Repeated heating and cooling cycles</li></ul><p>Our glass is specifically designed and tested for these conditions. This is why following proper candle care matters. Burning your candle on a heat-resistant surface, avoiding cold surfaces like marble or glass tables, and stopping use when 1/2 inch of wax remains all help ensure the container performs as tested.</p><h2 id="can-i-reuse-greenleaf-containers-for-food-or-drinks">Can I Reuse Greenleaf Containers for Food or Drinks?</h2><p>We don&apos;t recommend repurposing Greenleaf vessels for food or beverage consumption. While our glass passes safety standards for candles, it&apos;s not tested or certified as food-safe glassware.</p><p>Candle containers are designed for a specific purpose: safely holding burning candles. They haven&apos;t undergone the testing required for food contact surfaces.</p><h2 id="what-can-i-do-with-empty-containers">What Can I Do With Empty Containers?</h2><p>You have plenty of options for reusing your Greenleaf vessels in ways that don&apos;t involve food or drinks:</p><ul><li>Storage for small items (cotton balls, jewelry, office supplies)</li><li>Planters for succulents or small plants</li><li>Makeup brush holders</li><li>Pen and pencil cups</li><li>Decorative vases for dried flowers</li><li>Bathroom organizers</li></ul><p>Just clean out any remaining wax first. You can use the freezer method, hot water method, or oven method to remove leftover wax before repurposing.</p><h2 id="proper-use-prevents-problems">Proper Use Prevents Problems</h2><p>Glass issues are rare when candles are used correctly. To keep your Greenleaf candle burning safely:</p><p><strong>Use heat-resistant surfaces only.</strong> Never place candles directly on cold surfaces like glass or marble, which can crack from temperature changes.</p><p><strong>Avoid drafts.</strong> Drafts can cause uneven heating of the glass.</p><p><strong>Keep the wick centered.</strong> A wick that&apos;s too close to the side can create hot spots on the glass.</p><p><strong>Stop at 1/2 inch.</strong> When only 1/2 inch of wax remains, it&apos;s time to stop. Burning below this level can overheat the bottom of the container.</p><p><strong>Never leave burning candles unattended.</strong> Always burn within sight.</p><h2 id="the-bottom-line">The Bottom Line</h2><p>Greenleaf takes glass safety seriously. Every container is tested to meet strict ASTM standards, so you can enjoy your candle with confidence. Just follow the care instructions, and your candle will perform beautifully and safely from start to finish.</p><hr><p><strong>More questions for us?</strong> Call 1-877-GREENLEAF (1-877-473-3653) or email info@greenleafgifts.com.</p>

<p>All Greenleaf candles use <strong>cotton or paper wicks</strong> that are completely <strong>free of lead and zinc</strong>.</p><h2 id="why-wick-material-matters">Why Wick Material Matters</h2><p>The wick is the heart of a candle. It draws melted wax up to the flame, creating the light and fragrance you enjoy. The type of wick affects everything: how cleanly your candle burns, how evenly the wax melts, and how well the fragrance fills your space.</p><p>We use cotton and paper wicks because they&apos;re natural materials that burn cleanly and consistently. These wicks are specifically chosen to work with our proprietary soy-blend wax formula for optimal performance.</p><h2 id="lead-free-and-zinc-free">Lead-Free and Zinc-Free</h2><p>This might seem obvious, but it&apos;s worth stating clearly: <strong>Greenleaf wicks contain absolutely no lead or zinc.</strong></p><p>In the past, some candle manufacturers used metal-core wicks (wicks with a thin wire running through the center) to help the wick stand upright in the wax. Some of these metal cores contained lead, which could release harmful particles when burned.</p><p>The candle industry has moved away from this practice, and reputable manufacturers no longer use lead wicks. Greenleaf never has and never will. Our cotton and paper wicks stand up perfectly on their own without any metal reinforcement.</p><h2 id="how-cotton-and-paper-wicks-work">How Cotton and Paper Wicks Work</h2><p><strong>Cotton wicks</strong> are made from braided or twisted cotton fibers. They&apos;re soft, flexible, and burn steadily. Cotton is a natural material that creates minimal smoke when trimmed properly.</p><p><strong>Paper wicks</strong> are made from specially treated paper fibers. They&apos;re rigid enough to stand upright in the wax and burn consistently throughout the candle&apos;s life.</p><p>Both wick types work through capillary action. As the wick burns, it draws liquid wax upward, where the heat vaporizes it. That vapor is what actually burns, creating your candle&apos;s flame and releasing fragrance into the air.</p><h2 id="why-we-choose-natural-wicks">Why We Choose Natural Wicks</h2><p>Natural fiber wicks like cotton and paper offer several advantages:</p><p><strong>Clean burning:</strong> When trimmed to 1/4 inch and burned properly, they produce minimal soot.</p><p><strong>Consistent performance:</strong> They maintain a steady flame size throughout the burn.</p><p><strong>Optimal fragrance throw:</strong> They create the right flame temperature to properly release fragrance from our soy-blend wax.</p><p><strong>Safe materials:</strong> No metals, no synthetic materials, just natural fibers.</p><h2 id="wick-size-matters-too">Wick Size Matters Too</h2><p>It&apos;s not just about the material. The wick diameter must be perfectly matched to the candle size. Too small, and the wax won&apos;t melt to the edges (hello, tunneling). Too large, and the flame gets too hot, causing smoking and soot.</p><p>We extensively test each candle to ensure the wick size is just right for the container diameter and our wax formula. This testing is part of what makes Greenleaf candles burn so cleanly and evenly.</p><h2 id="caring-for-your-wick">Caring for Your Wick</h2><p>Even the best wick needs a little maintenance:</p><p><strong>Trim to 1/4 inch before each burn.</strong> This is the most important thing you can do for your candle. A trimmed wick creates the ideal flame size and prevents mushrooming (that little ball that forms on the wick tip).</p><p><strong>Recenter if needed.</strong> After extinguishing your candle and before the wax cools, use tweezers to gently center the wick if it&apos;s shifted.</p><p><strong>Remove wick trimmings.</strong> Don&apos;t let trimmed pieces fall into the wax. Fish them out before lighting.</p><p>A properly maintained wick means a better burn, better fragrance throw, and a longer-lasting candle.</p><h2 id="the-bottom-line">The Bottom Line</h2><p>Greenleaf uses only cotton and paper wicks, free of lead and zinc. Combined with our proprietary soy-blend wax and extensive testing, these natural wicks ensure your candle burns cleanly, safely, and beautifully from first light to last burn.</p><p>Quality materials matter. From our in-house fragrances created in Spartanburg, South Carolina to our tested glassware to our natural wicks, every component of a Greenleaf candle is chosen for performance and safety.</p><hr><p><strong>More questions for us?</strong> Call 1-877-GREENLEAF (1-877-473-3653) or email info@greenleafgifts.com.</p>
