One Light Table Lamp by Currey and Company from the Celadon Collection collection in Celadon Crackle / Clear / Antique Brass finish The name of the Celadon Crackle Table Lamp says it all, as this lovely vase-shaped creation is made of porcelain with a crackled celadon finish. The pale blue lamp's body sits atop an optic crystal base, and the scalloped shade is fastened in place with an optic crystal finial. The random crackle on this lamp will vary from piece to piece -- a hallmark of this artisanal treatment.
