什么是陶瓷餐具

更新时间:2019-03-25 18:37:03  浏览量:

陶瓷餐具,陶瓷的传统概念是指所有以粘土等无机非金属矿物为原料的人工工业产品。它包括由粘土或含有粘土的混合物经混炼,成形,煅烧而制成的各种制品。由粗糙的土器到精细的精陶和瓷器都属于它的范围。对于它的主要原料是取之于自然界的硅酸盐矿物(如粘土、长石、石英等),因此与玻璃、水泥、搪瓷、耐火材料等工业,同属于“硅酸盐工业”的范畴。 陶瓷餐具的烧制和应用在我国有着悠久的历史,其造型多样、色彩斑斓、手感清凉细滑,容易洗涤,深受国人喜爱。陶瓷餐具的制作方法分为釉上彩、釉下彩、釉中彩三种。釉上彩陶瓷用颜料制成花纸贴在釉面上或直接以颜料绘于产品表面,再经低温烤烧而成,由于烤烧温度达不到釉层熔融的程度,所以花面不能沉入釉中。用手触摸釉上彩陶瓷,感觉花面有明显的凹凸感; 釉中彩陶瓷的烤烧温度可令釉料熔融,颜料可沉入釉中,冷却后被釉层覆盖,制品表面平滑,手触无明显凹凸感; 釉下彩陶瓷全部彩饰在瓷坯上进行,施釉后经高温一次烧成,花面被釉层覆盖,看上去光亮、平整,手感光滑。
