“…In the last few decades, several archaeological and art historical studies have investigated the connections between these tiles, characterized by similar circumstantial motifs and illustrated topics, along with the number and location of the possible production workshops (Anderko, 2023; Bodnár, 1988; Cserey, 1974; Gruia, 2007; Hoššo, 2005; Jančiová, 2020; Kvietok & Mácelová, 2013; László, 2012; Mácelová, 2005, 2006, 2009; Mezei, 2013, 2016; Mordovin, 2015; Parádi, 1984; Rakonczay, 2018, 2020). These studies were recently complemented by systematic archaeometric research to determine the raw materials and production technology of the ceramic body, as well as of the glaze of the stove tiles found at various archaeological sites, using a multi‐analytical methodology (Györkös, 2022; Györkös et al, 2018, 2019, 2020). Based on the similarities and differences in the applied materials and production technology, the investigated tiles from seven sites were classified into three groups: (1) tiles from Besztercebánya/Banská Bystrica (Slovakia); (2) tiles from Eger, Salgó, Szécsény (northern Hungary) and Fülek/Fiľakovo (Slovakia); and (3) tiles from the castle of Csábrág/Čabraď and the monastery of Ipolyság/Šahy (Slovakia).…”
