Title: How do I remove Renaissance wax ?
Post by: Gladiateur on September 06, 2006, 01:51:57 pm

Hello,

I finished treating a case of bronze disease on a Nerva as with false patina (all gone) about two weeks ago.  I followed the instructions to the letter, finished with isopropyl alcohol, baking in the oven and eventual waxing.  Now, about two weeks after the coin was placed in a cardboard holder (adhesive, so the coin is supposed to be air-tight), BD is back again on a few tiny spots.  So I will have to try and treat it again.  How can I get rid of the Renaissance wax ?

Regards,

Pascal

I have used soap and hot water with a toothbrush followed by soaking in olive oil - but it was on a coin I decided after I was all done cleaning - needed some more cleaning. I've noticed no wax left after doing this and its now back to soaking in olive oil.

Hot water and soap will work, or alcohol, just like any other wax. If your coin is thick, more than 2mm, it may require soaking in a soda mix for at least a week with at least two changes of solution. Don't close it up for about 3 weeks. I generally watch the coins in open air for that amount of time,  watching for further out breaks. You can finish, ie wax, the coin, but watch for the reappearence.

Can you post some pics of the BD?  I've always thought one of my Connies had it, but then again it could just be dirt.

Here's one of mine, before and after an hour's simmer in sodium carbonate / sodium bicarbonate solution:
