Oil bottle for marching kit

[Peroni]

It will 'wick' a little but because the stopper is compressing the linen it usually stops at the neck of the container. My wife demonstrates Roman cookery, and she transports all her oil bottles in this way.

Ceramic vessels are ok, but I would advise a glazed interior. That way the oil will not leach through the ceramic onto the rest of your kit.

Did you have any leaching issues with your ceramic flask Paul?
