セラミック釉薬システムには、微細な鉱物粒子、顔料、不透明化剤、フリット粒子が含まれており、これらは製造と塗布の全工程で均一に分散された状態を維持する必要があります。釉薬スラリーが不安定だと、粒子が沈降したり、バッチ間で粘度が変動したり、塗布が不均一になったり、最終的な焼成面にピンホール、ハガレ、色むら、光沢の不均一などの欠陥が生じる可能性があります。
LANDERCOLLは、セラミック釉薬用途に特化したセルロースエーテル製品群を提供しています。製品の選択は、釉薬の種類、塗布方法、顔料システム、および特定の性能目標によって異なります。
懸濁安定性、粘度制御、結合性、釉薬塗布性能
CMCは、セラミック釉薬配合で最も一般的に使用されるセルロースエーテルです。釉薬粒子を均一に分散させ、保管中および製造中のスラリー性能を安定して維持するのに役立ちます。沈降を低減し、未焼成釉薬層の接着性を向上させ、バッチ間で一貫した釉薬厚みを維持します。
特殊なレオロジー調整、保水性、塗布制御
HPMCは、特殊な保水性、レオロジー改質、またはカスタマイズされた塗布挙動が必要とされる特定のセラミック釉薬システムで検討される場合があります。その使用は、フリットの種類、顔料システム、固形分、および塗布方法に基づき、配合試験を通じて常に検証される必要があります。
水性セラミックシステムにおける非イオン性粘度調整と懸濁支持
HECは、粘度調整や懸濁支持が必要な特定の釉薬スラリーや特殊セラミックコーティングシステムで使用されることがあります。HECは非イオン性であるため、一般的に電解質の干渉に対する感受性が低く、pHや可溶性塩分含有量が変動するシステムで有用です。

CMC helps keep glaze particles, pigments, frits, and opacifiers uniformly dispersed throughout the slurry. This supports more stable glaze slurry during storage and production, and more consistent application behavior — reducing the need for frequent re-mixing and preventing defects caused by particle segregation.
Cellulose ether helps adjust glaze slurry viscosity to match the requirements of the target application method — whether spraying, dipping, bell glazing, curtain glazing, or roller application. Proper viscosity control is essential for achieving consistent coating thickness and surface uniformity.
Before entering the kiln, the unfired glaze layer must adhere firmly to the ceramic body to prevent chipping, cracking, or detachment during handling and transport on the production line. CMC supports binding and helps improve the cohesion and mechanical integrity of the unfired glaze layer.
Cellulose ether helps manage water movement in the glaze layer during application and drying. Controlled water retention supports more stable drying behavior, reduces the risk of surface cracking, and helps maintain consistent glaze thickness from application to firing.
A suitable cellulose ether grade helps improve coating uniformity and surface coverage by supporting consistent flow, leveling, and adhesion behavior during application. Final surface quality depends on the complete glaze formulation, application equipment, and firing process.
Cellulose ether supports stable slurry behavior and helps reduce production variation caused by settling, viscosity drift, or poor particle distribution — contributing to higher production yields, fewer surface defects, and more reliable batch-to-batch glaze quality.
When ceramic glaze processing or surface quality fails, the cellulose ether grade, dosage, or system compatibility is often the first variable to review. The guide below maps typical symptoms to likely causes and practical cellulose ether support strategies.
Poor suspension or uneven particle distribution in glaze slurry.
CMC supports suspension stability — review grade selection and dosage level.
Poor viscosity control or application imbalance during spraying or dipping.
Improve rheology and application consistency with a suitable CMC grade.
Weak binding or low cohesion of the unfired glaze layer on the ceramic body.
CMC supports binding and unfired layer strength before kiln entry.
Dispersant, solids, pH, or electrolyte interaction affecting additive performance.
Test compatible cellulose ether grade and optimize dispersant-additive balance.
Poor dispersion or weak suspension in colored glaze systems.
Support pigment distribution and stability with properly matched CMC grade.
Viscosity too high or unsuitable rheology for spray glaze application.
Use suitable low-viscosity grade and optimized dosage for spray systems.
Drying stress or uneven moisture distribution in the glaze layer.
Support water retention and layer cohesion through grade optimization.
Raw material variation or poor additive balance across production batches.
Improve slurry stability and batch consistency through grade and dosage control.
Understanding the key variables that influence cellulose ether behavior in glaze systems is essential for successful formulation and production optimization.
Frits, feldspar, quartz, clay, pigments, and opacifiers influence suspension, viscosity, and adhesion.
Fine and coarse particles affect settling tendency, slurry flow, and surface smoothness.
High-solids systems require careful viscosity and rheology control.
Strongly influence slurry flow, particle distribution, and cellulose ether performance.
pH and soluble salts affect hydration, viscosity response, and suspension stability.
Spraying, dipping, bell glazing, and roller application require different viscosity profiles.
Speed, temperature, humidity, and layer thickness influence cracking and surface uniformity.
Kiln temperature, firing curve, and cooling behavior affect final fired glaze appearance.
Choosing the right cellulose ether requires balancing suspension stability, viscosity, application method, binding, water retention, surface coverage, drying behavior, and production consistency.

CMC (Carboxymethyl Cellulose) is the most commonly used cellulose ether in ceramic glaze formulations, providing suspension stability, viscosity control, binding, water retention, and application consistency. HPMC may be considered in selected specialty glaze systems, and HEC may be used in selected glaze slurry systems where non-ionic viscosity control is needed.
CMC helps improve glaze slurry suspension stability, viscosity control, pigment and particle distribution, unfired glaze adhesion to the ceramic body, water retention during application and drying, and surface application consistency. It is the primary functional additive for glaze processing performance.
Yes. Suitable CMC grades can help improve suspension stability and significantly reduce particle settling in ceramic glaze slurries during storage and production — supporting more consistent application behavior and reducing the need for frequent re-mixing.
Cellulose ether can help improve viscosity control, flow behavior, and application consistency, which supports better and more uniform surface coverage. Final surface quality also depends on glaze composition, application equipment, drying conditions, and firing process.
A common reference dosage range is 0.03%–0.50%, depending on glaze type, solids content, application method, particle size distribution, and cellulose ether grade. Spray glaze systems typically use lower dosages (0.03%–0.25%) while specialty glazes may require higher levels (0.08%–0.50%).
Viscosity drift may be caused by dispersant interaction, changes in solids content, pH variation, electrolyte level, particle settling, poor mixing, temperature fluctuation, or an unsuitable cellulose ether grade. Reviewing grade compatibility and optimizing the dispersant-cellulose ether balance can help stabilize viscosity.
Cellulose ether is an organic additive that burns out during firing. At typical dosage levels, properly selected cellulose ether grades do not adversely affect fired glaze appearance. Final fired surface quality depends on glaze composition, application thickness, burnout behavior, firing schedule, and kiln conditions.
Start with glaze type, particle size distribution, solids content, application method, target viscosity, pigment and opacifier system, suspension requirement, drying behavior, and firing conditions. LANDERCOLL can recommend suitable CMC or selected cellulose ether grades for testing based on your specific glaze system parameters.
Yes. Share your ceramic glaze type, application method, solids content, pigment system, current production issues, and performance targets. LANDERCOLL can recommend suitable CMC, HPMC, or HEC options and provide samples, TDS, SDS, CoA, and dosage guidance for laboratory evaluation.
