How We Help
At CelSian, quality improvement focuses on predictability, stability, and control across the entire process. We help you understand why defects occur, anticipate quality risks, and implement solutions that prevent recurrence. By understanding and controlling raw materials, melting, refining, combustion, and operation, CelSian helps glassmakers achieve stable, repeatable quality, even under changing production conditions. Our approach combines digital modeling, real-time process intelligence, laboratory insight, and hands-on furnace support to improve refining behavior, combustion adjustment, melt homogeneity, and operational consistency, ensuring quality is maintained across shifts, campaigns, and pull rates.

Celfos: From Process Control to Quality Control
Celfos shifts furnace operation from reacting to process conditions to actively steering glass quality. By combining AI with CFD modeling, it gives you forward-looking control over quality up to 48 hours ahead.
How Celfos Helps:
- Predict quality issues early.
- Optimize combustion for balance.
- Speed up color and product changes.
- Support operators in real time.
- Keep performance consistent.
From Lab Insight to Better Glass Quality
A container glass manufacturer faced persistent quality issues; blister defects, reaching 2% rejection on one production line. The issue was traced to batch behavior and redox imbalance, causing unstable melting. Using High Temperature Melting Observation System-Evolved Gas Analysis (HTMOS-EGA) and on-site evaluation, targeted adjustments to the batch recipe and redox conditions were implemented.
Impact:
- 1% reduction in blister rejection.
- Improved melting and glass surface stability.
- More stable furnace temperatures.
- Lower operating temperatures, supporting efficiency gains.
Knowledge That Elevates Quality
Optimizing glass quality isn't just about technology; it’s also about people. Through Celsian Academy’s expert-led training programs, we equip your team with the practical knowledge to identify root causes, interpret lab results, and make informed process decisions. Because when your people understand the “why,” they deliver better “how.”
