In this blog, we will discuss the reasons why candle vessels can occasionally crack and ways to reduce or prevent it from occurring in the future. Always check glassware upon receiving it for any damage during shipment. You should never burn a candle in cracked or damaged glassware. Contact us immediately for a replacement.
Why did my candle's glassware crack?
The most common cause of candle glassware cracking is over-burning.
Allowing the candle to burn too closely to the base of the vessel creates too much heat concentration in the base of the wick, causing the glass to break. Discontinue using the candle when 10mm of wax remains or the steel tab is visible.
Off-centre wicks or moving wicks are another cause for cracked glassware. Burning the candle for periods longer than recommended can cause the wick to move off centre. When a wick is off centre is too close to the glass the heat distribution is uneven and leads to excess heat stress on one area of the glassware, which can cause cracking. Always remember to peel tabs on base of refills and press the refill firmly to the glass.
Ways to prevent cracked glassware
There are many things you can do to prevent or reduce the chances of your candle’s glassware from cracking or breaking.
- Ensure the wood wick is always trimmed to the correct length before each light. We recommend a wick length of about 5mm.
- Only burn the candle in rooms free from draughts. This will ensure the flame creates an even wax pool and prevent burn acceleration.
- Keep the wax pool free of debris. Debris can catch fire which includes dust, ash, and condensation.
- Always follow burn times, these can be found on the sticker on the base of the glassware.
- If the flame flickers or becomes too intense blow out, check wick length and for draughts.
- Always burn on heat-resistant surfaces and away from flammable items.
- Discontinue use when 10mm of wax remains or the steel tab is visible.
- It is good practice to check your glassware for cracks and breaks before each use. If you notice any damage to the glassware discontinue use immediately.
