Sorry, no etymologies found.
It is almost, if not totally, impossible to hermetically seal pottery containers due to the variations that occur in the neck diameter and shape (slight ovality).
'I may mention that a study of defects in the vertical circle of a small Altazimuth formerly used by me, and an inspection of the operations in the instrument-maker's work-shop, have convinced me that the principal error to be feared in instruments of this class is ovality of the graduated limb; this cannot be eliminated by two microscopes, and such an instrument should never be fitted with two only.
On land in the US, Wireline Isolation Scanner* cement evaluation technology was deployed for XTO Energy and successfully identified salt encroachment, casing ovality, and a potentially catastrophic 7-in casing collapse in a well in the Rockies.
Capwatcher for pin holes, short shot, cavity number, colour, ovality including metal closures
-- 98 kgf/mm2 for AISI grade 1050 wire rod measuring 9.2 mm or more but not more than 9.8 mm in cross-sectional diameter, processed exclusively by heat-treating on an in-line fused salt bath patenting process that results in having a tensile strength tolerance range of plus or minus 5 kgf/mm2, and having an ovality of no more than 0.30 mm.
The project company, together with the insurance companies, is investigating the best way to deal with this problem: replace it completely, try to improve its roundness by squeezing it back into shape (the giant steel "pinch" for that was being prepared on site when we visited) or, quite possibly, use it as it is (by luck, it is the bottom part which was damaged, ie the part that goes in the sand, so ovality is less of an issue there as long as the vertical penetration in the soil can still be controlled).
