There's a recipe for this somewhere (raw linseed and an extra rapid

I was looking for patination oil in Wickes, and on the linseed oil can
it said "do not use on lead" or some such thing. Anyone know what
patination oil is, and what it actually does chemically ?
Simon.

The wickes data sheet says of patination oil:
contents:
White spirit
CAS:64742-82-1 (this is white spirit type 1)
Xn; F; N

No idea what the last bit means. But apart from this it is just white
spirit.

You can also get lead-cote, a non-solvent based alternative from
Jewsons.
I'm off to get some tomorrow. Its in a spray bottle.

Simon.

These substances form a semi-permeable membrane on the lead that
slowly allow the atmospheric gases and moisture etc through, stopping
the white carbonate until the dull grey patina has build up. They wear
away over time.
Anything you can think of that does this, would work.
