沈括《梦溪笔谈》记载毕昇泥活字印刷工艺甚为详细,但有关毕氏泥活字的制造工艺,只有“以胶泥刻字,薄如钱唇,每字为一印,火烧令坚”四句话。由于无实物可考,后世对毕氏泥活字的制造工艺研究很难具体,我们推测当时可能是用一个个胶泥字坯直接刻阳文反书字而成。清代安徽泾县翟金生泥活字的制造工艺虽无系统的文献记载,但活字实物及活字印本的发现为研究泥活字印刷工艺提供了可靠依据,这在活字印刷术发展史上有着重要的学术价值。关于翟氏泥活字制造工艺问题,张秀民先生曾撰文总结,张秉伦先生论述更为精辟。我们在此基础上,对翟氏泥活字制造工艺作了进一步研究,通过实验测试明确了泥活字的矿物组成和烧成温度范围,并就泥活字印刷术进行了模拟实验。 Shen Kuo, “Meng Xi Bi Tan” records Bi Sheng clay movable type printing process is very detailed, but the Bi-type clay movable type of manufacturing process, only "to clay lettering, thin as money lips, Four sentences. Because there is no material test, future generations of Bi-type mud-type words of manufacturing technology research is difficult to specific, we speculate at that time may be a piece of clay blank directly engraved Yangwen anti-book words made. Although there is no systematic literature on the manufacturing process of Zhai Jinsheng slime in the Jing county in Anhui province in the Qing Dynasty, the discovery of slogans in kind and typefaces provides a reliable basis for studying the slop printing process. This has important academic value in the development of type printing. About Zhai mud clay production process problems, Mr. Zhang Xiu Min had written summary, Mr. Zhang Binglun more brilliant discussion. On this basis, we further study Zhai’s mud-making technique, and confirm the mineral composition and firing temperature range of the mud-type character through experiments and experiments.
