Technical criteria to evaluate before issuing bulk purchase orders to domestic distributors.
Commercial candle vessels require annealed soda-lime glass rated for thermal stress up to 140°F–160°F during wax pouring and flame combustion. Avoid repurposing food packaging or decorative glassware lacking container candle thermal certification, as uneven wall thickness causes catastrophic thermal shock cracking.
Industry standard closures use continuous thread (CT) finishes—most commonly 70-400 (70mm diameter, 1 thread turn) and 58-400. Ensure metal closures have plastisol or polyethylene foam liners to lock in volatile organic fragrance compounds. For friction-fit bamboo or wooden lids, inspect the food-grade silicone gasket fit to prevent scent seepage during seasonal storage.
Glass jars are sold by fluid brimful volume, NOT wax weight. Because molten soy wax has a specific gravity of approximately 0.86 g/ml, an 8 oz fluid volume amber jar holds approximately 5.8 to 6.2 oz of molten wax with a standard 1/2-inch wick clearance.
Glass is heavy and freight carriers classify it under specific freight classes. For orders over 400 lbs shipped via LTL freight, always request liftgate service if your facility lacks a commercial loading dock (– accessorial fee). Inspect all pallet wraps immediately upon delivery and photograph damaged cartons within 48 hours for insurance claims.
Standard procurement details, case tiers, and dispatch information.
No. You cannot safely pour candles into thin decorative glassware, drinking tumblers, or unrated food jars. Commercial candle jars must be made of thick, annealed soda-lime glass engineered to withstand localized heat cycles up to 160°F from an open flame without thermal shock cracking.
The industry-standard starter size is an 8 oz straight-sided amber or clear glass jar with a 70-400 neck finish. It provides a 35 to 50 hour burn time, fits a single wick cleanly (e.g. CD 12 or ECO 8), and holds approximately 6 oz of molten wax.
Brimful volume measures the total liquid capacity to the very top rim in fluid ounces. Because soy wax expands when molten and has a specific gravity of ~0.86 g/ml, net wax weight is roughly 15% to 20% lower than water volume. An 8 fluid oz jar holds approximately 5.8 to 6.2 oz of wax plus fragrance.
Continuous thread (CT) finishes like 70-400 and 58-400 are the most versatile. A 70-400 finish accommodates black metal lids, rustic gold closures, and brushed aluminum screw tops with plastisol heat seals.
Distributors like Berlin Packaging, CandleScience, and Lone Star Candle Supply offer case-tier ordering with no minimum order thresholds ( MOQ), allowing makers to order single 12-pack cartons before stepping up to pallet volume.
When ordering LTL freight (>400 lbs), always declare whether your delivery address is residential or commercial, and whether you require a hydraulic liftgate. Failing to pre-book liftgate service incurs carrier accessorial penalties of to .
Most industrial distributors (like Berlin Packaging) sell jars and lids as separate SKUs so makers can customize metal, wood, or cork finishes. Candle-specialty distributors (like CandleScience) frequently offer bundled case packs with matching lids included.
