Title: Do you wax ?
Post by: Dominic T on November 13, 2018, 05:36:49 pm
Hello. I would like to take the pulse of different members about waxing our coins. Im ambivalent on the question if I should proceed with my bronzes or not. Just not sure I really like the  wet look  and also wondering if I must do it for the conservation of these ancient treasures.  So what do you think, specially you, experienced collectors ? Thanks for your precious opinion.

Nope ... and I'm mad at the few coins that I've purchased that have been waxed (I'm not a fan of that fake look)

=> I like my coins the same way that I like my women woman => honest, beautiful and with zero makeup

I wax some bronze coins.  Only with Renn wax.

Sometimes it is to preserve poor patinas/surfaces.  Sometimes for the look.  It can also help keep out moisture - so as long as there is not already an issue within the coin metal itself it can help with preservation.

I find that Renn wax does not usually make coins look too shiny.  Not if used sparingly.

I wax almost all my bronzes... I find it brings out detail, keeps any risk of damage from moisture at bay, and to be honest, I just like the look...
   Should any future custodians of my coins disagree, a wipe with nail varnish remover on a tissue, and it's gone... No harm done...

I do too with my bronzes after drying.  I also like the look and anyone after me can wipe it off no troubles.

Hi folks,

I use Renaissance wax on coins that I previously treated for bronze disease. But that is the only situation I have used it in the past. Regarding 98-99% of my bronze coins, I leave them alone.

Hello:  Yes, I wax bronze coins with Ren wax- three very thin coats.  I like the look and agree it helps bring out detail sometimes.  I also like the idea of protecting the coin during handling and from moisture.

To the point about not locking in moisture, in the past I have heated coins to above 212 for a short period to drive out any water, then waxed immediately after they cooled down.  However, from my experience with Civil War brass artifacts I learned about solvent dehydration.  Water is completely miscible in many alcohols--methanol, ethanol and isopropanol etc.  I use 91% isopropanol you can buy in a pharmacy (or can when this virus thing is over).  If you soak a group of coins in alcohol any water in the coins will become completely dissolved in the alcohol, meaning there will be very little water in the coins when removed from the alcohol bath after a few days.  Alcohol evaporates quickly and with a little help from a blow dryer or space heater you can drive out that alcohol quickly, then wax. By avoiding the oven I eliminate the risk of changing the appearance--sometimes darkening-- of the coins.

I can attest that Ren wax is easily removable-- I have removed it from two groups of coins to clean them a little more.  A short soak in mineral spirits, wet brushing with a tooth brush, and then a rinse in clean mineral spirits does the trick. My point is, Ren wax is not permanent; its completely undoable. 

Also, I use Briwax on restored iron and brass Civil War artifacts.  It's a high quality wax and much less expensive than Ren wax.  I've never used it on coins though, and because the coins are so small the cost of Ren wax is not that much of an issue.  On a large number of large Civil War artifacts Ren wax would get very expensive.  The Briwax does a good job.  See attached photos of Union breast plate and Confederate 6 pound cannon ball.

I do not wax my bronzes; for me less is more.
