   Plasticity is crucial for shaping ceramic bodies during forming processes like pressing, extrusion, or slip casting. Choose plastic clays such as ball clay and kaolin (china clay), which provide the necessary workability and green strength before firing.

   Key considerations:

   • Test plasticity using standardized methods like the Atterberg limits or rolling tests.
   • Ensure the material maintains its shape without cracking during drying and retains dimensional accuracy.
   • Balancing plasticity with drying shrinkage is critical to prevent warping or deformation.
3. Firing Temperature Compatibility

   The raw materials must be compatible with the intended firing temperature range of your production process. Vitreous ceramics are typically fired between 1,100°C and 1,300°C, depending on the composition.

   To ensure successful sintering and vitrification:

   • Match the maturing temperature of individual materials (e.g., feldspars, fluxes) with the kiln's operating range.
   • Avoid materials that melt too early (causing slumping) or too late (incomplete densification).
   • Conduct small-scale firing trials to evaluate thermal behavior and phase development.
4. Test for Vitrification

   Vitrification is the transformation of the ceramic body into a dense, glassy, and non-porous structure. Materials like feldspar (as a flux) and silica (quartz) (as a network former) play vital roles in promoting glass formation.

   Evaluation steps:

   • Analyze water absorption rates after firing—true vitrification results in absorption below 0.5%.
   • Monitor shrinkage and density changes during firing to assess densification.
   • Use dilatometry or XRD analysis to study phase transitions and glassy phase development.

   Optimal vitrification enhances strength, impermeability, and long-term durability.

5. Granulometry Standards

   The particle size distribution (granulometry) of raw materials significantly influences the ceramic body’s workability, drying behavior, and fired properties.

   Consider the following:

   • Fine particles increase plasticity and surface smoothness but may lead to higher drying shrinkage and cracking.
   • Coarser particles improve green strength and reduce warping but can affect surface finish.
   • A well-graded mix (combination of fine, medium, and coarse particles) optimizes packing density and reduces porosity.

   Use sieve analysis or laser diffraction to characterize particle size and adjust blending ratios accordingly.

6. Purity Level

   Impurities such as iron oxide, titanium, or organic matter can negatively impact the color, strength, and translucency of the final product.

   To ensure high purity:
