Coins in airstill

[The_blue]

The only one with pure copper on the outside is the new one.. copper isn't porous, the inner core won't leak out.

I have been doing this for a while and I think I can speak with experience and certainty - if they are the newer magnetic coins (1p & 2p) they blister and then the inner will/is exposed.
I have some to hand if you need photographic evidence.

It is also worth noting that 'old fashioned' copper stills were copper for a reason and it wasn't convenience. Copper has beneficial effects on the spirit.

Try things for yourself if you like, but the recommendation for future readers of this post is copper.....or something inert such as the glass or stainless milk savers.

I've got a length of old water pipe ready to chop up .

I save all my copper pipe offcuts and hit them with a hammer once or twice for this use.
Simples.

Going to chop up some copper pipe I have in the shed

For a couple of quid a pipe cutter does make a much better and safer job than a hacksaw.

Look at this on eBay http://www.ebay.co.uk/itm/131120075557

Nice rounded ends with one of those,
