陶瓷的产生和发展，其实是同人们的生活和生产实践紧密相连的，在大约70万年以前的原始时代，人们就泥巴晾干后用火烧烤坚硬的盛器用于盛水，存放食物等等，这便是陶器产生的初始。最新的考古资料表明，我国境内目前发现最早的陶器遗址是位于江西万年县内的仙人洞遗址、广东英德青塘、灵山滑岩石洞、广西桂林甄皮皮岩。其主要品种有灰陶、彩陶、黑陶和几何印纹陶等，手法粗糙，构图新颖流畅，表现了当时制陶的技术水平。

仪器介绍

    The FOX 50 Heat Flow Meter is an accurate, easy-to-use instrument for measuring thermal conductivity according to ASTM C518 and ISO 8301. The FOX 50 provides rapid results in a compact footprint. The instrument is configured with the identical high performance features and proprietary technologies of the larger FOX systems including thin film heat flux transducers, digital thickness measurements, responsive temperature control, plus an integrated contact-resistance correction. Covering a wide range of temperatures, the FOX 50 is an ideal choice for measurements of medium-conductivity materials such as plastics, ceramics, glasses, composites, concrete and more.
