hotel porcelain-cup and Saucer
Hotel porcelain cup and saucer sets are manufactured from feldspathic porcelain with water absorption below 0.5 percent and a dense microstructure. The firing process is carried out at temperatures between 1350 and 1400 degrees Celsius. Final density ranges from 2.3 to 2.5 grams per cubic centimeter. Flexural strength is at least 90 megapascals, and surface hardness is approximately 6 on the Mohs scale. A transparent or decorative glaze layer with thickness of 0.2 to 0.4 millimeters is applied. Typical cup capacity ranges from 80 to 250 milliliters.
The cup structure consists of a cylindrical or conical body with a reinforced integrated handle. Wall thickness is generally selected between 3 and 5 millimeters to balance strength and weight. The saucer is designed with a diameter between 120 and 160 millimeters and reinforced rims to prevent edge chipping. Thermal shock resistance is evaluated within a temperature differential of 120 to 150 degrees Celsius. The glazed surface exhibits near zero porosity and chemical resistance within a pH range of 2 to 11. Quality control includes cup to saucer fit testing, rim impact evaluation, and glaze uniformity inspection.
