We also cast church bells, ship bells, gongs, and conduct renovations of old bells. In bell production, we draw upon the centuries-old expertise of ancient foundry workers in creating bell structures accumulated over many years. These methods are described, among others, by Vanoccio Biringuccio in 1540 and in the encyclopedia ‘Krunitza’ from 1780, as well as in materials collected by Tadeusz Szydłowski in 1922. We combine the experiences of past bell founders with modern casting technology supported by years of experience, enabling us to produce high-quality bells with harmonious sound.
