Client Background
As a glass candle holders supplier, Mosteb was approached by an established interior candle company from France, supplying scented candles to lifestyle boutiques and concept stores across Paris, Lyon, and Marseille. The client ordered a custom ribbed glass candle holder with a soft smoke-gray tint and a weighted base for their new collection.
This design was selected to match contemporary French interior trends—subtle texture for visual depth, a neutral tint to complement different candle colors, and a heavier base to improve safety for home use. The company chose Mosteb because of our factory-direct manufacturing, consistent quality control for large-volume orders, and our ability to translate design ideas into practical, repeatable production.
Challenges
During sampling and early production, the client faced two realistic challenges:
- Ribbed Texture Uniformity: Early samples showed slight variation in rib depth, which affected how light reflected through the glass.
- Stability Concerns with Heat Exposure: Some holders became slightly warm and unstable during extended burn tests, raising safety concerns.
Cause Analysis
Mosteb’s technical team conducted a detailed investigation. We found that inconsistent mold pressure during forming caused uneven rib depth, while insufficient base thickness distribution allowed heat transfer to affect stability.
To resolve these issues, we ran mold-pressure calibration tests, simulated extended candle-burn conditions, and reviewed the annealing curve to ensure even glass density across the holder.
Solution
- Optimized mold structure to ensure consistent rib depth on every unit.
- Increased base density slightly while maintaining the original visual proportions.
- Adjusted annealing time to improve heat resistance and structural balance.
- Introduced batch-level stability and heat exposure testing before shipment.
Result
The final glass candle holders met all safety and aesthetic requirements, achieving uniform ribbing, improved heat stability, and consistent weight distribution. The French company successfully launched the collection across multiple retail channels and has since appointed Mosteb as its long-term glass candle holders supplier for future product lines.
