Meakin Mark Comparative Test (Trnio Plus)

One of the tests conducted at the Digital Archaeology Lab lately was to create a model of the same sherd using every application that we had at our disposal, so as to have comparative data. This particular model was made using Trnio Plus, a photogrammetry iPad application. The sherd itself is an ironstone basal sherd from a plate; it features a transferprinted maker's mark indicating that it was made by J. & G. Meakinn (Hanley, Stoke-on-Trent, England). The mark itself features what is referred to as the "modern" Royal Arms and can be used to date this particular sherd to after 1890. If you look closely, you can make out the beginning of the word "Ironstone" and the start of "J. & G. Meakin."

Meakinn（英国特伦特河畔斯托克市汉利区）生产。该标识带有所谓的‘modern’皇家纹章，可将该陶片的年代判定为1890年之后。若仔细观察，可辨识出‘Ironstone’一词的前缀以及‘J. & G. Meakin’的开头字样。数据集来源：Objaverse 1.0 / Sketchfab
