How pillars, tapers and tealights are made
Pillars are poured into metal or silicone moulds around a wick, or pressed from fine wax powder in a machine. Poured pillars can shrink and need a second pour; pressed pillars are fast and even but can crack or crumble if the powder or press pressure is wrong. Coloured pillars are either dyed through or white candles over-dipped in a coloured layer.
Tapers are made by dipping a wick again and again in molten wax until the right thickness builds up, or by moulding. A taper has to fit a standard holder socket and stay straight, so its base diameter and the way it is cut matter as much as its look.
Tealights are small pressed pellets dropped into an aluminium or clear plastic cup, with a short wick held on a metal tab. Because they are sold by the hundred, small faults such as an off-centre tab or a short wick add up to many complaints.
What we check on pillars, tapers and tealights
| Check | How it is checked | What fails |
|---|---|---|
| Diameter and length | Caliper at base and top; tapers tried in the holder sizes in your plan | Taper too thick to fit or too thin to stand firm; pillar out of tolerance |
| Straightness | Tapers rolled on a flat table; pillars stood on glass and checked for lean | Bent tapers, leaning or rocking pillars, uneven bases |
| Surface and colour | Against the colour standard in daylight; over-dip checked at the base | Shade outside the limit, white bloom, scratches, air bubbles, over-dip cracking or peeling |
| Pressed-candle integrity | Pillars tapped and checked for layers or cracks | Cracks, crumbling edges, layers that split |
| Wick | Centred, upright, cut to the agreed length, primed with wax | Off-centre, too short to light, unprimed |
| Burn screen | Pillars and tapers burned in still air, tapers in their holder; tealights in a holder | Dripping on a "dripless" candle, guttering through the wall, taper bending, flame above the agreed height, smoking |
| Burn time | Tealights and tapers burned to the end and timed | Burn time below the claim on the pack |
| Tealight cup and tab | Cup checked for splits and leaks; tab position; flame goes out at the tab | Split cups leaking wax, tab off-centre, flame continuing on the last of the wax |
| Count | Pieces per pack counted | Short packs |
Common pillar, taper and tealight candle defects and how they are classed
| Defect | Typical cause | Class |
|---|---|---|
| Taper or pillar tips over while lit | Wrong diameter for the holder, uneven base | Critical |
| Tealight cup splits and leaks hot wax | Thin or damaged cups | Critical |
| Flame does not go out at the end of a tealight | Wick tab missing or too low | Critical |
| Burn time below the pack claim | Wick too large, light pellet | Major |
| Heavy dripping on a "dripless" taper | Wax blend or wick size wrong | Major |
| Bent tapers | Stored warm or packed loose | Major |
| Colour off the standard | Dye batch change | Major or minor by difference |
| Light bloom on the surface | Wax migrating, cool storage | Minor |
Your defect list decides the final class.
Standards and rules that apply
- US. The lead ban in 16 CFR 1500.17(a)(13) applies to metal-cored wicks; a tealight's metal tab holds the wick but is not a core, so check what the wick itself is made of. ASTM F2417 (fire safety for candles) and ASTM F2058 (fire-safety labelling) are voluntary and often written into retailer specifications.
- EU. The GPSR applies to all candles. EN 15493 sets fire-safety requirements and EN 15494 the safety labels. EN 15426 tests sooting of single-wick candles up to 100 mm in diameter; larger and multi-wick pillars cannot be tested by that method and are judged on visible soot instead.
- Scented versions. A scented pillar or tealight brings the fragrance labelling questions covered on the scented candle page.
A burn screen at the factory is not a certified test. For lab reports we pull and seal samples through lab testing coordination.
Packing, heat and your purchase order
Tapers and slim pillars bend if they are stored or shipped warm, and coloured candles can mark each other in film. The inspector checks that tapers are packed flat and tight in boxes, that pillars are wrapped so surfaces do not touch, that tealight stacks are sleeved so cups do not crush, and that finished stock is kept away from roofs and walls that heat up in the afternoon.
- Type, wax, diameter, length and tolerance; holder sizes the candle must fit.
- Colour standard and whether colour is solid or over-dipped.
- Burn time claim and the "dripless" or "smokeless" wording, if used.
- Wick type and supplier; tealight cup material.
- Pieces per pack and packing method.
Pillars and tapers are sold with holders: see candle holder and lantern inspection.
