How to Choose Candle Jars for Candle Making

Updated

Choose candle jars by matching three things: the wax and wick you plan to use, the burn time you want, and how the finished candle will be used (gift, sample, or everyday home candle). Glass, tin, and ceramic each behave differently with heat and scent, and jar diameter matters more than height when you size a wick. Buy from a candle-making supplier that lists jar capacity and heat resistance, and confirm shipping and minimums before committing to a large order.

Compare jar materials first

Material What it gives you Watch for
Glass (clear) Shows wax color and layers; classic look; easy to label Needs heat-resistant glass; check for "candle-safe" or tempered wording
Glass (colored/frosted) Hides imperfections, softer glow Color can mask uneven burns and soot
Tin Lightweight, shippable, good for gifts and travel Dents easily; lid fit matters for scent retention
Ceramic Premium look, opaque, good for gifts Heavier shipping cost; verify it is rated for candle use

For a first batch, clear heat-resistant glass is the easiest to troubleshoot because you can see tunneling, wet spots, and wick performance.

Match jar diameter to wick size

Wick charts are usually indexed by jar diameter, not volume. A tall, narrow jar and a short, wide jar can hold the same amount of wax but need different wicks.

  • Measure the inside diameter at the widest point where the wax sits.
  • Use the wick manufacturer's chart for your wax type (soy, paraffin, or a blend) and fragrance load.
  • If a jar is wider than your wick's rated range, you get tunneling and a weak melt pool; too large a wick overheats the wax and can soot.

Fragrance load also affects wick choice. Higher fragrance loads can make wax burn hotter or cooler depending on the oil, so test a small batch in the actual jar before scaling up.

Pick capacity by intended use

  • Samples and testers: small jars, typically a few ounces, so you can test scent throw and wick performance cheaply.
  • Gifts and favors: mid-size jars that look finished with a lid and label.
  • Everyday home candles: larger jars for longer burn times, but confirm the wick is rated for that diameter.

Estimate burn time from the wax weight the jar holds, not the jar's nominal size, and leave headspace at the top so the flame has room.

Check safety and presentation details

  • Confirm the jar is heat-resistant and intended for candles.
  • Use a lid that fits well if you want to preserve scent between burns.
  • Plan label placement before buying: straight-sided jars are easier to label than curved ones.
  • Avoid jars with narrow necks that trap heat or make wick centering difficult.

Buying from a supplier

Aztec Wholesale Candle and Soap Making Supplies (candlemaking.com) lists Candle Jars among its candle-making supplies alongside IGI waxes, soy wax, and fragrance oils, and states same-day shipping and 40+ years in business. The site also promotes a 10 fragrances for $10 offer, online orders only, one per household per month, not valid with other coupons, with pickup orders required in the same month as the coupon. Pricing for jars is not shown in the available page content, so check the product pages and cart for current cost per jar, minimums, and shipping before ordering.

A practical approach: buy one or two jar styles in the size you need, test them with your chosen wax and wick, then reorder the winner in quantity.
