CMC and selected cellulose ether solutions for glaze suspension, viscosity control, binding, water retention, surface application, and processing stability in ceramic glaze systems.
LANDERCOLL cellulose ether helps ceramic glaze manufacturers improve glaze slurry stability, application consistency, surface coverage, suspension behavior, and production reliability across wall tile, floor tile, porcelain, sanitaryware, and specialty ceramic glaze systems.
From spray glaze and dipping glaze to colored, opaque, and specialty formulations — the right cellulose ether grade supports stable suspension, controlled viscosity, and consistent surface application before firing.

Ceramic glaze formulations require stable suspension of mineral particles, pigments, frits, and functional additives. During production and application, glaze slurry must maintain proper viscosity, smooth flow, good surface coverage, and stable adhesion to the ceramic body before firing.
LANDERCOLL provides cellulose ether products for ceramic glaze applications — with CMC (Carboxymethyl-Zellulose) as the primary grade for suspension stability, binding, viscosity control, water retention, and improved glaze application behavior. Selected HPMC and HEC grades are also available for customized glaze systems where special rheology, flow control, or processing stability is required.
A suitable cellulose ether grade helps improve glaze uniformity, reduce settling, support better surface application, and maintain consistent production performance — directly contributing to higher yields, fewer surface defects, and more reliable fired glaze quality.
Ceramic glaze systems contain fine mineral particles, pigments, opacifiers, and frit particles that must remain uniformly dispersed throughout production and application. If the glaze slurry is unstable, particles may settle, viscosity may drift between batches, application may become uneven, and the final fired surface may show defects such as pinholes, crawling, color variation, or uneven gloss.

The following table provides reference dosage ranges for cellulose ether in ceramic glaze applications. Actual dosage should be determined through formulation testing and production-scale validation.
These dosage ranges are starting references only. Final dosage should be confirmed through slurry viscosity testing, suspension testing, application trials, drying evaluation, surface inspection, firing trials, and production-scale validation.

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.

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.

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.
