Blue and White ceramics - Egypt


Blue on White ceramics: the reciprocal influence of Chinese porcelain on European and Middle Eastern ceramics - Egypt

This brief investigation of blue on white ceramics is focused on Egypt as my previous investigation suggested that the potters of Basra moved to Cairo around the 10th century and the rise of the Mamluks.
Here is the previous post on the ceramics of Iraq

Pre 10th century
The Ancient Egyptians produced some beautiful items with blue overglaze such as these bowls (1, 2, 3). Over a long period of time, the Egyptians were producing items such as the iconic scarab in solid blue or turquoise overglaze (4). This range of blueish-turquoise items is sometimes call Egyptian blue (copper-calcium-silicate) but others appear to have been coated in a cobalt glaze the source of which is suggested to be evaporite deposits. Interestingly, the combination of blue and white doesn't seem to be culturally attractive and there are very few extant examples from this time (5).

In the 5th - 7th centuries Egypt was controlled by the mostly Christian, Copts. Coptic earthenware featuring blue motifs seems to have consisted of red clay objects that were fired (or dried) and then decoratively painted. Many jars were painted with lines of text however there are some examples of figures or patterns. The British Museum collection contains a number of whole (6) and fragmented items (7) from this period. This decoration method appears to be traditional in the region as similar ones can be found dating to the 18th Egyptian Dynasty (8) (1543 - 1292 BCE).

The 7th century saw the Byzantinians fighting a loosing battle for control of Egypt against the Rashidian Caliphate. The islamic influence of the Rashidians and later the Umayyadian Caliphate resulted in the conversion of much of the population. I have yet to find any items with blue glaze from this period but the Rashidians are important to note as they established the capital at Fustat (now part of Cairo), near what was Coptic Cairo. After the Umayyadian Caliphate (the largest Empire in the world at the time), the Abbasid Caliphate came to power.

10th-13th centuries
The 10th century saw the Baghdad based Abbasidian Caliphate suffering from internal political strife. Sections of the empire were breaking away, and trade relationships were fluctuating. Fustat (Old Cairo), under the Fatamid dynasty, was rising as a political power at this time, resulting in the shift of production from more marginalized regions of the empire, i.e. Basra, to Cairo (Attwood). I have found no extant BoW items that support this theory as there is no evidence of the simple designs employed by the artists of Basra in items recovered from Egypt. The Egyptians do seem to have adopted the lustreware first developed in Iraq around this time. It's possible the lack of local cobalt, the local penchant for turquoise and the desire for the more decorative lustreware squashed the transfer of the BoW designs.

In the 10th century common ceramic objects in Egypt are still being dipped in overglaze before being fired (9) as part of the ongoing traditional decorative theme. The blues are becoming more varied by the 12th century with the introduction of a more purplish tint to the glaze (10). This may indicate an iron contamination in the cobalt source. This shift away from the more traditional lapis or turquoise colourings may be a result of the Islamic influence or a reduction in quality/quantity of pigment sources. The blue-purple strainer is an interesting item because typically these lovely objects are natural clay (11) and rarely glazed. I have found a couple of extant items that were glazed in turquoise as well (12, 13) indicating the love of this colour is deeply rooted in the Egyptian potters traditions. It seems that even though more complex and decorative methods are available, the production of common household goods such as filters and lamps (14) continued to involve simple glazing techniques. Lamps are of particular interest because they need to be glazed to prevent the terracotta from absorbing the oils. Lamps are also a common household object that would require mass production. Colours range from yellows (15), to greens and turquoise (16) and the rare blue (17). (side note: I love the pied colour of this one - 18).

Support for Attwood's suggestion on the move of Basra potters to Cairo is derived from lustre-ware items (19) recovered from Fustat. Stylistically these items are very similar to objects produced across the Abbysaid Empire (20) and even imported from Spain (21). This makes identification to a hobbiest like myself particularly challenging and I initially assumed the stylistic diversity at Fustat was solely due to their geographic location and the importation of high-level ceramics. However sherds such as 22 are marked with 'sa' which may be a potters mark, a workshop or a Fustatian tradition, either way, the item has been identified as Egyptian in origin. Essays on Islamic ceramics on the Ashmolean Museum propose that the Basra potters migrated to Egypt bringing the skills of lustreware. These potter families them migrated to Syria and later spread to Spain after the fall of the Fatamid dynasty in the 12th century.

13th - 14th century
By the 13th century, the Mamluks had risen to power in Egypt ousting the Abbysaidians. On a side note: the Egyptian Mamluks seem to have made the greatest imprint on history, but the Delhi Sultinate was also controlled by the Mamluks which is often overlooked by hobbies scholars discussing this period in the middle east. Through the 13th and 14th centuries, Egypt was an important trading hub connecting the Mediterranean, the Red Sea, India and the East Indies.
Where the potters of Basra produced stylistically individual designs which are reasonably easy to identify. If anything, the potters of Fustat can be most easily identified through the use of solid Egyptian blue and turquoise glazes. This method of identification unfortunately, doesn't work for styles that require the use of different glazes. Items recovered from Fustat have a broad range of stylistic influence with sgraffito (23), incised and dipped (24) and polychrome underglaze (25) items all being produced from the 10th - 14th centuries. The position of Fustat as the hub of trade networks allowed local potters to adopt patterns and techniques from across Europe, the Middle East and Asia. A good example of this is the black and blue (BBW) items produced in Fustat during the 14th century (26). Some blue and black fragments have been recovered from Fustat (27, 28) and the style is quite similar to items produced in Syria at the time (29, 30)

Blue on White in Egypt
The production of BBW items in Fustat indicates the potters are conversant with the method of applying a white underglaze, then decorative elements and a clear overglaze. Sherds of Chinese porcelain (31) have been recovered from Fustat confirming the transport of such items to Egypt. There is no doubt these items influenced local designs. Sherds have been recovered that sport chrysanthemum like flowers (32), ducks (33) and other Chinese motifs (34). A number of sherds have been recovered from Fustat with patterns are reminiscent of Asian and iznik designs (35, 36, 37, 38, 39, 40). While I would like to wax lyrical regarding BoW trends in this region, I simply do not have sufficient extant objects to do so.

As well as the importation and imitation of Chinese BoW items, the Mamluks were producing BoW tiles (41, 42, 43, 44, 45, 46) very similar to the turquoise and blue hexagonal tiles being created in Syria with an almost Iznik flavour (47).
