Thanks both!,
I think I've achieved the seasoning process now.
It seems the manufacturers give them a coating of wax, of some sort to keep them good while being shipped/stored.
I gave the a good scrub with hot soapy water and rinsed, then boiled some water in them for a couple of hours over a fire, poured away the water, final rinse, then left them to drain, upturned by the fireside, finally I gave them a spray with some 1cal olive oil.
Fortunately Retro, I do have a good pair of welding gloves, that I use with my wood burning stove.
For the first meal, I'm planning on 'mixed bean n' bacon stew', so you may wanna stay upwind ;-)
