A fantastic item of mid century modern decor, created in the legendary "barovier i tosso-murano" workshops, most sought after "hybiscus" edition. made of best craftsmanship murano "rugiadosa" glass, (a layer of uniform microcrystals added and fused to the the inside of the shade for a superb refraction of light, a proprietary technique pioneered by ercole barovier in the late 50's), on polished brass support. uses four e27 light bulbs\. For a warmer/goldish light, 2700k or less led light bulbs need be used, while for a whiter/colder light, 4000k or higher led light can be used. in impeccable condition, complete, perfectly functional. diameter-60cm (24.62 inches), height-20cm (7.6 inches), this piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
