摘要：艺术设计是日用陶瓷产品的未来发展趋势,中国日用陶瓷产品自诞生之日起就与人们的生活息息相关,长期受传统观念的束缚,这使得国内日用陶瓷产品在传统的"庇护"下缓慢发展,导致产品缺乏创新意识和独特性设计。随着历史的发展变化,又出现新的需要。由于消费观念的变化,人们更加关注那些产品外形有张力,视觉冲击力强,色彩感、装饰感、节奏感丰富的日用陶瓷产品设计,人们希望日用陶瓷产品设计集观赏、实用于一体,且有一定的个性和艺术性。在这种背景下,提倡日用陶瓷的艺术化设计具有积极的意义,这对于提升日用陶瓷产品的设计理念,以及满足人们的"生活审美化"、"审美消费"起着重要作用。文章从日用陶瓷产品的造型、装饰、材料三个方面展开论述,实现日用陶瓷产品艺术化设计的途径。
