The invention relates to heat-resistant archaistic iron crude ceramic and a preparation method thereof. The heat-resistant archaistic iron crude ceramic comprises the following raw materials in partsby weight: calcined kaolin, water-washed kaolin, petuntse, iron-ore slag, feldspar and mullite. In the heat-resistant archaistic iron crude ceramic, the weight content of silicon dioxide is 54-56%, the weight content of aluminum oxide is 34-36%, and the weight content of ferric oxide is 5.0-6.0%; the density is 1.8-2.1 g/cm , the water absorption rate is 3% or below, the volume expansion coefficient is 90-105*10<-7>/DEG C, and the thermal stability comprises that the crude ceramic passes through a test at the temperature of 200 DEG C for 3 times; the production cost is low, the expansion coefficient is low, the thermal stability is good, and the simple and rough aesthetic feeling of the crude ceramic is well reserved. 本发明涉及一种耐热的仿古铁质粗陶和制备方法，原料包括如下重量份的各组分：煅烧高岭土，水洗高岭土，瓷泥，铁矿渣，长石和莫来石；所述耐热的仿古铁质粗陶中，二氧化硅的重量含量为54～56％，氧化铝的重
