Know Your Candle Vocabulary

Here are a few great reasons for why it’s important to brush up on your candle vocabulary:

  1. It helps you get faster and more accurate advice when reaching out to customer service or message boards.
  2. It helps you understand the process of candle making
  3. It helps establish you within in the industry.
  4. Ultimately, knowledge of the terms (and the common occurrences that they define) will significantly reduce your production and troubleshooting time.

As with learning any language, some of these terms can be quite confusing. Terms like afterglow, tart, mushrooming and frosting are common terms that you will become accustomed to recognizing and there are many more.

To make it easy for you, we’ve compiled a comprehensive glossary of terms for everything you need to know to master the art of candle making.

GET TO KNOW THESE COMMON CANDLE MAKING TERMS

AFTERGLOW: The light emitted from the wick after the candle is put out.

CRACKLING BOOSTER WICK (also known as an Adhered Wick): The Crackling Booster Wick is an Crackling Wick in various sizes and thicknesses combined with a .1875″ (4.8mm) Crackling Wick “booster” adhered vertically down the center of the wick. The Crackling Booster Wick is an ideal option for vegetable wax blends, soy wax, beeswax candles or candles with heavy fragrance or dye loads.

BURN CYCLE: (not to be confused with Burn Rate or Burn Time). A Burn Cycle is burning a candle for four hours, blowing it out, letting it cool and then most likely repeating. This process is mainly used for evaluating wick performance as well as general candle testing.

BURN RATE: The amount of wax consumed per hour in grams. Burn rates will vary based on vessel size, wax type, and the heat emitted from your wick. A good rule of thumb to follow is small candles with small wicks can burn for seven to nine hours per 1 ounce of wax while those with large wicks burn approximately five to seven hours per 1 ounce of wax.

BURN TEST (also known as Test Burn): A specific, controlled, structured burn generally used to determine proper wick size. This is step 4 in the candle making process and one of the most important steps. After wax, vessel sizes, and fragrances have been chosen, it’s important to conduct a burn test to evaluate the best wick size and type for your specific candle. See our full blog post for more on burn testing.

BURN TIME: The total amount of time it takes for a candle to burn to completion. Different factors will contribute to different burn time such as wax type, wick size, and vessel size.

CARBON BUILD-UP (also known as Mushrooming): The ball of carbon build-up on a wick. This is most common with cotton wicks but not as much with Wooden Wicks. To prevent build up on Wooden Wicks be sure to trim the wick and clear any carbon buildup between burns.

COLD THROW: The amount of fragrance emitted from a candle that is not burning. This is unique to each candle maker’s preference. Certain waxes have a better cold throw than others. For example, 100% Soy Wax has a reputation for not having a very powerful cold throw.

FINISHING (with a heat gun): This is when a heat gun is applied to the top of the wax to smooth out any sinkholes or imperfections in the candle after the original setting.

FLASH POINT: The temperature at which a fragrance can ignite when exposed to a spark or flame. This can can be found on the Fragrance Safety Data Sheet or MSDS. See MSDS for more information.

FRAGRANCE LOAD (also known as Scent Load): The percentage of fragrance concentration in one batch of candles. We recommend using 8-10% fragrance per batch of candles. We have created a Fragrance Percentage Chart to help you calculate your desired percentage load.

FROSTING (also known as Bloom): The formation of white crystals on the surface of natural waxes (soy) caused by cooling at a different rate. This is not ideal with candle making as it can ruin the aesthetic of the candle. To help eliminate frosting, try heating your vessels and adjusting pour temperatures.

GLASS ADHESION (also known as Wet Spots, Pull Away and Delamination): Areas where the wax pulls away from the glass caused by inaccurate pouring temperatures or rapid ambient cooling. This is most common with soy and paraffin waxes.

GUTTER: Excess melted wax that can run down the outside of a pillar candle.

HANG UP: Remnant wax that remains on the wall of container candles when the candle has finished burning. This happens as a result of tunneling and can be prevented by making sure that your candle is achieving a full melt pool.

HOT THROW (also known as Warm Throw and Scent Throw): Similar to cold throw, the fragrance emitted from a candle when it is burning. This is unique to each candle maker’s preference. Various wax types will give better hot throw. 100% Soy Wax has a reputation of poor hot throw and you may need to increase fragrance load up tp 12% for desired scent throw.

JUMP LINES (also known as Chatter and Stuttering): The unintended horizontal lines or rings around the sides of either a container or pillar candle.

MELT POINT: The temperature at which the wax begins to liquify. There are different melt points for each wax type so be sure to accurately follow the instructions of your chosen wax.

MELT POOL: The liquid pool of wax of a candle while burning. As a rule of thumb, you should expect a full melt pool to be achieved within 2-3 hours of burn time. An ideal melt pool at 4 hours is ½” in depth.

MIX TEMPERATURE: The recommended temperature of the wax when you add your fragrance and color. Each wax is different and fragrance should be accurately mixed at the corresponding required temperature. See WAX for more information.

MOTTLING: The “snowflake” type appearance of the wax in the finished candle (pillars). MSDS: Material Safety Data Sheets are the product safety information sheets supplied by the manufacturers of your materials (wax, fragrance, colorants, additives, etc). These are important to reference for questions regarding flash point, melting instructions, and application information regarding the product’s ingredients and materials.

MUSHROOMING: The carbon build up on the top of the candle wick (both after and while it is burning). Also see Carbon Buildup.

OUT OF BOTTLE: The first experience of a fragrance once the bottle is opened. This is referred to as out of bottle or OOB evaluation.

POUR TEMPERATURE: The required temperature for pouring the fragranced and or colored wax into the vessel or mold. This is different for every wax type so be sure to follow the instructions for your specific wax.

POWER BURN: Burning a candle for longer than 4 hours. This is often categorized as 8+ hours. This is dangerous and we do not recommend it.

RELIEF HOLES: Holes that are manually poked into a candle as it cools to release air pockets that can form. Relief holes are used to eliminate sinkholes in conjunction with a heat gun. See Heat Gun for more information.

SINGLE PLY WICK: A Single-Ply Wick is a wick made from a single piece of wood in varying thicknesses. They are currently available in .02, .03, and .04 thicknesses.

SINK HOLES: Holes, craters or actual cavities in the wax caused by air pockets trapped in a finished candle. This is fairly uncommon but most common with soy candles. They can be prevented by accurately following instructions for melting and pouring temperatures and ensuring that candles are setting on a flat, undisturbed surface. They can be fixed using relief holes and finishing with a heat gun. See Heat Gun for more information.

SWEATING: (also known as leaching): When the fragrance separates from the wax (often collecting on the top of a container candle in small beads or even a small pool). This is fairly uncommon but is often caused by rapidly moving a candle from one temperature to another. Soy wax is most sensitive to extreme temperature changes. Read more on our blog post What is Candle Sweating?

TART (also known as Wax Melts): Scented waxes with no wick that are melted for fragrance in a “warmer”. These are different than candles and can be created using soft waxes and high quality fragrances. They are often used for aromatherapy purposes.

TRANSITION TEMPERATURE: The temperature or temperature range where a wax cooling from liquid state to solid state is changed from non-crystalline form to crystalline.

TOP POUR (also known as Re-Pour and Second Pour): An additional pour after the candle has set to either fill in a sink-hole or smooth out the top.

TUBE WICK: Tube Wicks provide a gorgeous circular shaped flame and work well in all wax blends. They are created to be used alone, but may be used with cotton wicks or wooden strip. Alone a Tube Wick will create a 2.5″ / 63.5 mm melt pool. For larger diameter containers, we suggest using multiple wicks evenly spaced apart. Tube Wicks are only available in a 6″ / 152.4 mm length, so to achieve the optimal height, cut the wick to your specific length with a pair of scissors.

TUNNELING: When the wick is too small for the diameter of the candle and a full melt pool cannot be reached, a “tunnel” is formed. A wax wall will be left around the perimeter of the candle.

VESSELS: Also known as the jar or container that your candle is created in. They can be made from varying materials and can be found in different shapes and sizes.

VISCOSITY: A waxes ability to resist movement when melted. For example, honey has a high viscosity and water has a low viscosity. Some waxes are more viscous than others.

WAX: The filler substance that a candle is made from. The most common types are Paraffin, Beeswax, Soy, Coconut, and Vegetable Blend. We’ve created two natural premium wax blends, our Virgin Coconut Soy and Coco Apricot Creme waxes. Learn more about these wax types on our blog Choosing the Best Candle Wax.

WHISPER WICK: The Whisper Wick is our softest crackling wooden wick and creates a unique, teardrop shaped flame. It is made from a light-colored wood and is available as Single-Ply, Booster, or Dual.

WICK DOWN: (also known as Size Down) During testing when you need to try one wick size smaller to try for optimal results. With wooden wicks, it could mean to go down one size in thickness or width or both.

WICK UP: (also known as Size Up) During testing when you need to try one wick size larger to try for optimal results. With wooden wicks, it could mean going up a size in thickness or width or possibly both. It could also mean adding a booster strip.

WOODEN WICK: A single-ply, adhered, multi-layered, curved or decorative shaped wick made from 100% wood. All of our wooden wicks are naturally processed and sourced and manufactured with pride (and great skill) in the USA.
