I accept that a partially lead lined coffin may well be capable of floating in the short term (depending upon volume displacement) but there is also a secondary problem arising from the effect of seawater salinity on lead - but anyway, I won't go into that now.

I really don't know 'owt about the techniques and procedures in lining a coffin with lead; I assume the objective is to slow the decomposition of the body, in which case it makes far more sense to wrap the corpse itself in lead sheeting rather than line the coffin itself and then solder the surrounds.

I’ve attached a little sketch comprising 2 end views, feet up from a body in a coffin, one with the body wrapped in lead sheet and the second one with the coffin lined with lead, soldered and with a lead lid as well – I just can’t see how the coffin can be waterproof and as such will, after time, invariably sink.

Is that less in those coffins?
