When the inside of a jar becomes red-hot from the flame, the glass expands there. The outside of the glass is in contact with the cooler air in the room and expands more slowly. We call this difference in expansion \u201cthermal shock.\u201d When the material cannot withstand this stress, cracks form.    <\/p>\n\n<p class=\"wp-block-paragraph\">Not every glass is suitable for candles. Drinking glasses or inexpensive vases from discount stores are often made of standard glass that already contains internal stress from the factory. For your hobby, be sure to use <a href=\"https:\/\/www.youwish.nl\/en\/handmade\/packaging-en-4\/glass-containers\/\">glass containers<\/a> that are specifically designed and tested for heat. Good candle jars often meet the ASTM F2179 standard for annealed glass. This means the glass has undergone a process to remove internal stresses.    <\/p>\n<div class=\"woocommerce columns-3 \"><ul class=\"products columns-3\">\n<li class=\"product type-product post-290085 status-publish first instock product_cat-candle-making product_cat-packaging-en-4 product_cat-glass-containers has-post-thumbnail taxable shipping-taxable purchasable product-type-variable\">\n\t<div class=\"commercekit-wishlist mini\" data-product-id=\"290060\"><a href=\"#\" class=\"commercekit-save-wishlist\" data-product-id=\"290060\" data-type=\"list\" title=\"Wishlist\" aria-label=\"Wishlist\"><em class=\"cg-wishlist\"><\/em><span><\/span><\/a><\/div><a href=\"https:\/\/www.youwish.nl\/en\/buy\/packaging-en-4\/glass-containers\/30cl-candle-glass-round\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/www.youwish.nl\/en\/buy\/packaging-en-4\/glass-containers\/30cl-candle-glass-round\/\" title=\"30cl Candle Glass Round\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img fetchpriority=\"high\" decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2024\/04\/30cl-glas-300x360.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"30cl Candle Glass Round\" sizes=\"(max-width: 360px) 147px, \" \/>\t\t\t\n\t<\/div><\/div><\/a><\/div><div class=\"woocommerce-card__header\">\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/www.youwish.nl\/en\/buy\/packaging-en-4\/glass-containers\/30cl-candle-glass-round\/\" aria-label=\"30cl Candle Glass Round\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">30cl Candle Glass Round<\/a><\/div><div class=\"my-price\"><span class=\"wts-price-container\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>1.85<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>1.53<\/bdi><\/span><\/span><\/span> <span aria-hidden=\"true\">&ndash;<\/span> <span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\" aria-hidden=\"true\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>1,350.00<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>1,115.70<\/bdi><\/span><\/span><\/span><span class=\"screen-reader-text\">Price range: &euro;1.85&euro;1.53 through &euro;1,350.00&euro;1,115.70<\/span> <small class=\"woocommerce-price-suffix\">incl.

The wick acts as the engine of your candle and determines how hot it gets. A common mistake is choosing a wick that\u2019s too thick in an effort to quickly create a wide pool of melted wax. However, a wick that\u2019s too thick produces a flame that\u2019s too high and causes excessive heat against the sides of the glass.   <\/p>\n\n<p class=\"wp-block-paragraph\">If a flame becomes too large or starts to flicker, it can come into direct contact with the side of the glass. Direct contact with the flame greatly increases the risk of breakage. In addition, soot buildup indicates incomplete combustion. It\u2019s therefore a good idea to read up on <a href=\"https:\/\/www.youwish.nl\/en\/candle-making\/choosing-right-wick\/\">choosing the right wick<\/a> for your specific combination of wax and fragrance oils.

Hold each glass up to the light for a moment before you begin. Do you see a scratch, a bubble, or a small imperfection? If so, it\u2019s best not to use that glass for a candle. The heat will target that exact weak spot and cause the glass to crack.    <\/p>\n\n<p class=\"wp-block-paragraph\">The position of the wick in the glass also affects safety. A wick that is not positioned exactly in the center causes uneven heating of the glass wall. You can <a href=\"https:\/\/www.youwish.nl\/kaarsen-maken\/hoe-voorkom-je-een-off-center-kaarslont\/\">prevent an off-center wick<\/a> by using centering aids or special guides while the wax is setting. Also, make sure the glass is clean and dry to ensure the <a href=\"https:\/\/www.youwish.nl\/en\/handmade\/candle-making\/wax-candles\/\">candle wax<\/a> adheres properly.   <\/p>\n\n<h2 class=\"wp-block-heading\">Working with gel wax and other types<\/h2>\n\n<p class=\"wp-block-paragraph\">If you\u2019re working with gel wax, you need to be extra careful. Gel wax burns hotter and melts at a higher temperature than, for example, soy wax. Because gel wax is often transparent, crafters sometimes choose decorative glassware that isn\u2019t heat-resistant. Never do this. Gel wax has a melting point between 70 and 85 degrees and requires glass that can withstand this constant heat. Also pay close attention to the <a href=\"https:\/\/www.youwish.nl\/kaarsen-maken\/wat-is-het-vlampunt-van-geurolie\/\">flash point of fragrance oils<\/a> when using additives in your projects.     <\/p>\n\n<h2 class=\"wp-block-heading\">Is it a good idea to reuse candle jars?<\/h2>\n\n<p class=\"wp-block-paragraph\">It\u2019s tempting to clean an empty glass jar and refill it with wax. However, manufacturers often advise against this due to material fatigue. The glass has already been heated and cooled many times during its first life cycle. This process can weaken the structure in ways that aren\u2019t visible. A second round of heat could then be just too much. It\u2019s better to use old jars as pen holders or storage containers for small items. Safety takes precedence over recycling when fire is involved.      <\/p>\n\n<h2 class=\"wp-block-heading\">Safety Rules for Burning<\/h2>\n\n<p class=\"wp-block-paragraph\">You can make the safest candle, but the user also needs to know what they\u2019re doing. Include clear instructions on your label. The most important rule is the 1\/2-inch rule. Stop burning the candle when there\u2019s about 1 to 1.5 centimeters of wax left at the bottom. Without this buffer of wax, the heat is transferred directly to the bottom of the glass.    <\/p>\n\n<p class=\"wp-block-paragraph\">Never let a candle in a glass container burn for more than 3 to 4 hours at a time. Otherwise, the glass will become too hot for the surface it\u2019s resting on. Also, never place candles in a draft. A draft causes an unstable flame that can flicker toward the edge of the glass, creating extreme localized heat there. For professional manufacturers, <a href=\"https:\/\/www.youwish.nl\/en\/buy\/services-en\/fire-safety-tests-for-candles-tuv-certified-en-154932019\/\">fire safety tests are available for candles<\/a> that comply with the European EN 15493 standard. This provides assurance regarding the flame stability and the integrity of the container.     <\/p>\n<div class=\"woocommerce columns-3 \"><ul class=\"products columns-3\">\n<li class=\"product type-product post-349664 status-publish first instock product_cat-candle-testing product_cat-services-en has-post-thumbnail virtual taxable purchasable product-type-simple\">\n\t<div class=\"commercekit-wishlist mini\" data-product-id=\"349468\"><a href=\"#\" class=\"commercekit-save-wishlist\" data-product-id=\"349468\" data-type=\"list\" title=\"Wishlist\" aria-label=\"Wishlist\"><em class=\"cg-wishlist\"><\/em><span><\/span><\/a><\/div><a href=\"https:\/\/www.youwish.nl\/en\/buy\/services-en\/candle-testing\/candle-burning-process-laboratory-test\/\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"woocommerce-image__wrapper\"><a href=\"https:\/\/www.youwish.nl\/en\/buy\/services-en\/candle-testing\/candle-burning-process-laboratory-test\/\" title=\"Candle Burning Process Laboratory Test\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\"><div class=\"shoptimizer-plp-carousel-container\"><div class=\"shoptimizer-plp-image-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"360\" src=\"https:\/\/www.youwish.nl\/wp-content\/uploads\/2025\/10\/Burning-Process-300x360.jpg\" class=\"attachment-woocommerce_thumbnail size-woocommerce_thumbnail\" alt=\"Candle Burning Process Laboratory Test\" sizes=\"(max-width: 360px) 147px, \" \/>\t\t\t\n\t<\/div><\/div><\/a><\/div><div class=\"woocommerce-card__header\">\t\t\t\t<div class=\"woocommerce-loop-product__title\"><a tabindex=\"0\" href=\"https:\/\/www.youwish.nl\/en\/buy\/services-en\/candle-testing\/candle-burning-process-laboratory-test\/\" aria-label=\"Candle Burning Process Laboratory Test\" class=\"woocommerce-LoopProduct-link woocommerce-loop-product__link\">Candle Burning Process Laboratory Test<\/a><\/div><div class=\"my-price\"><span class=\"wts-price-container\"><span class=\"wts-price-wrapper\"><span class=\"wts-price-incl wts-active\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>250.00<\/bdi><\/span><\/span><span class=\"wts-price-excl wts-inactive\"><span class=\"woocommerce-Price-amount amount\"><bdi><span class=\"woocommerce-Price-currencySymbol\" translate=\"no\">&euro;<\/span>206.61<\/bdi><\/span><\/span><\/span> <small class=\"woocommerce-price-suffix\">incl.
