What is macro-crystalline
glaze?
Macro-crystalline glazes, an enchanting form of ceramic art, reveal a world where pottery surfaces are adorned with large and distinct crystal formations, echoing a rich history dating back to ancient Chinese pottery during the Song Dynasty. This mesmerizing effect is achieved through a unique chemical dance, activated by high-temperature firing processes and specific metallic oxides like zinc and titanium.
The allure of macro-crystalline glazes lies in the remarkable appearance of well-defined crystals on the pottery’s surface, creating highly esteemed patterns and colours. Artists embrace the capricious nature of crystal formation, experimenting with glaze recipes and firing techniques to craft unique masterpieces.
Despite being a challenging endeavour, pottery adorned with macro-crystalline glazes has fascinated artists and collectors since its introduction in 1850s Europe. Major factories abandoned these glazes due to inconsistency and cost, but they are now experiencing a resurgence, with modern studio potters leading a crystalline renaissance. The advent of electronically programmed kilns has made these glazes more accessible, with artists utilizing new technology to produce outstanding specimens.
This complex and technically demanding process requires patience and finesse, and artists invest significant time perfecting their techniques. For those intrigued by macro-crystalline glazes, experienced ceramic artists and institutions offer valuable resources, workshops, and classes to guide your artistic journey.
Macro-crystalline glazes represent a timeless art form, bridging tradition with modernity, captivating contemporary ceramic artists, and enthusiasts alike. The second golden age of these glazes is explored in-depth in the book “Macro-Crystalline Glazes” by Peter Ilsley, providing exhaustive insights, techniques, and visual inspiration for experienced makers, as well as those preparing to face the crystal challenge for the first time. This valuable resource is also a reference for collectors who admire the dramatic beauty of crystals.
