and updated in these communities, serving to feed concepts of identity that were quite different from those of the dominant Luso-Brazilian society.  
De Souza (2015) shifted the focus from decoration to the morphology of the vessels and their potential to help us understand the enslaved people's material practices, analysing a morphological pattern common to ethnographic records from central and southern Angola and its relationship with vessels from eighteenth-century Goiás and Minas Gerais, which received a large contingent of Africans from the aforementioned Angolan regions. The vessels had a concave base, an inverted oval shape and a cylindrical neck and were used in Angola to cook corn, cassava and beans. In Brazil, bases were flat and the pieces featured two handles; these modifications were representative of the interaction between the groups in colonial society and the incorporation of European references. The adoption of flat bases served to make the vessels suitable for resting on the flat surfaces of colonial furniture, on tables in particular, unlike the concave bases found in Angola, designed for use in fireplaces where meals were cooked. The tables were linked to different rules of sociability, with a similar logic underpinning the addition of handles, which allowed the users greater control over the vessels when transporting and serving their contents. These vessels were therefore adapted to the colonial logic; similarly, the groups of Africans producing and using them had also adapted to the colonial logic. The shifts in the morphological pattern between Angola and Brazil represented the emergence of new practices in the diasporic contexts, including both continuities and transformations.
