With regard to the Renaissance Wax, I was wondering about using linseed oil. Has anyone ever heard of doing this?
Yeah from flax..Generally, linseed oil contains approximately 9-11% saturated (5-6% palmitic acid and 4-5% stearic acid) and 75-90% unsaturated fatty acids (50-55% linolenic acid, 15-20% oleic acid) (20).
Well, linseed oil should come from the seeds of the linseed plant As far as being an acid, yes technically but, consider milk has lactic acid.
Do people use milk on coins? That should come with 25 to life...milk is for eating, damn it! Flax is linseed or at least that's what Wikipedia says.
OK, OK...linseed oil plant...flax...whatever What I was thinking of was that linseed oil is what is used in oil paint. It air cures to a plastic after some time. I was just wondering if this could be used in liu of the Renaissance Wax.
I wouldn't put anything on them. And definitely not linseed oil. Leave them out in the air for a few months, checking them every couple of weeks, to make that bronze disease doesn't show up, i.e. the sudden appearance of a bluish-green powder building up on the surface. This is highly unlikely, but it is possible since you have recently exposed surfaces that have been covered in gunk for a long time. But really, there's no reason to coat them with anything. If you must put something on them, Ren Wax is probably the best option, even if it is unnecessary.
Here's the one that arrived the most cleaned from and uncleaned "premium" batch from noble roman. I need a better camera... I'm working on Identifying it now!
Coins are made of metal. There is no need to put anything on them. Linseed oil dries and creates a coating over the coins, which keeps oxygen from reaching the coin's surface and slowly repatinating over time. Plus, if there is any moisture left on the surface when the oil is applied, that moisture is trapped and will not evaporate. Save the linseed oil for furniture and oil paints. Today, many collectors curse the Victorian-era collectors who coated their prized coins with varnish. 150 years from now, future collectors will be cursing us for coating coins with Ren Wax and linseed oil. (Of course, we'll all be dead by then, so whether or not we should care what they say about us is a legitimate question.)
The "drying" with linseed oil is the reaction of the unsaturation of the compound with atmospheric oxygen, creating a crosslinked polymer barrier. Is this better or worse than Ren Wax?
What I don't like, is that I have notifications telling me there are replies and when I check if someone is offering more stuff I can use..... It's linseed... You already seem to have your mind made up about the topic no matter anyone else's opinion. You're just hijacking my post until someone validates your decision. I have my mind made up, Ren Wax, so please, stop it and make your own post about linseed. You're being rude, in my opinion. I asked you to stop and three times I've come back and three times I've seen my post go further from the information I'm seeking.
These threads are discussions and go where the readers here take them... that's what makes them fun. Don't take offense to someone adding their thoughts to the discussion, even if it isn't exactly the advice you are looking to get. Once you hit the post button, "your" post becomes the board's. Telling people to go away bums people out, making everyone less likely to reply to your questions. Be welcoming to everyone's input and everyone will be generous with their knowlege. Welcome, take it easy and have fun with the meandering discussions.
Well as a result I've unfollowed my post so go ahead. Take it away, until someone echoes your opinion. I'm done here.
Wow, sore loser...not even loser, I think cleaning and preservation go hand in hand. Forgive me if I offended anyone other than the OP.
