The malachite used in the first decades of the century, both ain the Imperial lapidaries like Peterhof and Ekaterinburg but Stalso in the private workshops like Maderni, mainly came fro m possiblethe two Urals deposits respectively at the south and north o f CollectionsEkaterinburg, and these are generally of two clear types. Th e Alexandrafirst, used here masterfully for this tazza, is characterized b y Mediciconcentric layers of small stalactites and is quite vivid gree n Petersburgin colour. The other – a shimmering variegated malachite- i s nra stone in plain dark green, whose mass is composed of a sharmultitude of crystals To work with both types of malachite, the andRussians had also perfected the ‘Russian mosaic’ technique, surfaccutting the malachite into small pieces of veneer between t wAand four millimeters thick, sorting them for their patterns, a nthen after grinding and polishing, carefully cementing them tNicolathe metal or stone form of the object, and skillfully masking thjoints with a paste of powdered malachitevase-amphora circa 1824-25 (The Hermitage Museum,Petersburg) according to Galberg’s designs it isthat he supplied Medici vase Royal(inv.no.

IVAN IVANOVICH GALBERG (1782-1863)Ivan Ivanovich Galberg, an architect and designer, wasat the Imperial Academy Arts until 1798.HeThisThere are not many prominent examples of pre-1830smalachite creations, and there are only a very few earlypatinatedmalachite works of a comparable scale to the present tazza The reasons are multiple: malachite in such quantity enabli ng acontinuous pattern of such large scale was rare; malachite wasexpensive, especially in such amounts, and covering a largebody with a veneer of malachite required an advanced level ofeducatedcraftsmanship only held in a few workshops. The present tazza therefore seems to be part of a small gro upof malachite objects that kicked off production of large scal e Hisvases in the St Petersburg and Ekaterinburg lapidary worksfrom about 1825. Ivan I.Galberg was instrumental in this, as buildingshe would supply the drawings for these projects, both for th e titleproduction in Imperial workshops, but also in private ones, awhich would also supply the Imperial household. benefitswasthen an assistant to the architect Giacomo Antonio DomenicoQuarenghi, then served as an architect at the Cabinet ofMajesty and participated in the construction theMikhailovsky Palace, the Alexandrinsky Theater and otherSt.Petersburg.
