TENMA KIRIKO / TENMA CUT GLASS
About 180 years ago / 1840s / Late Edo–Meiji Period
Tenma Kiriko developed from the glassworking culture around Osaka’s Tenma district, where thick glass and deep grinding became distinctive. Modern Osaka also produced pharmaceutical and scientific glass, and those polishing skills fed into decorative sake cups and drinking glasses.
In Japan, Tenma Kiriko is known for a bold, practical Osaka character. Deep cuts are made into thick bases and walls so that, once liquid is poured, patterns reflect repeatedly across the bottom and can appear almost kaleidoscopic.
Where many cut-glass traditions focus on surface pattern, Tenma Kiriko deliberately designs internal reflection. A single cut can multiply through glass and liquid, making one motif appear several times. The vessel functions almost like a small optical device.
