Flange
The flange is a functional and aesthetic element in the architecture of ceramic containers with lids. It is commonly presented as an internal step, a lip or a protruding surface at the mouth of the container, whose main mission is to keep the lid centered and stable, preventing its displacement.
In utilitarian contexts, a well-designed flange guarantees the protection of the contents, avoids spills and improves the preservation of aromas and flavors. On the other hand, in ornamental or design pieces, the flange can assume a decorative role, adding aesthetic nuances, visual rhythms or textural contrasts. Material, thickness, height, shape and finish influence the quality of the fit between lid and body, demanding careful planning during modeling and post-firing calibration.Interesting Fact
Flanges have been an integral part of ceramic vessels since ancient times, allowing the lids of Greek amphorae and vessels to be securely held in place. In certain cultures, the presence of complex flanges on ceremonial vessels indicated social hierarchy or the specific function of the container, giving them a symbolic as well as practical role.Helpful Tip
Before producing a batch of lidded containers, create prototypes to adjust the flange dimensions. A flange that is too narrow will make it difficult to fit the lid, while one that is too wide will create instability. Experience and critical observation will make it easier to find the optimum balance.
