Featured Thoughts on Renwax?

It's BENZENE, a known carcinogen and common impurity in many organic oils/solvents. It is not an intentionally added component. It's only mentioned in the SDS because it must be classified when it exceeds 0.1% to warn the end-user of a carcinogenic hazard. Everyone in the industry knows the issues with benzene and they go through great lengths to make sure it's well below reportable amounts otherwise their SDS's will get hit with cancer warnings.....a sure path to reducing your sales.

I remove traces of water from metal surfaces and residues frequently in the lab with low temperature ovens. Usually a 60-80°C is quite sufficient, you don't have to exceed the boiling point of water!

Waxes are long chain hydrocarbons, either naphthenic or paraffinic. Considering they mentioned benzene on the SDS, I suspect they are naphthenic in the product. The solvent they dissolve it in just makes the wax easier to use for the customer - it greatly reduces the viscosity.

I like the idea of fully drying a coin before applying since it not only prevents moisture from getting to the surface, it will also seal in moisture which may help corrosion.....especially the HCl induced corrosion common to ancients.

 

Toothpaste from back in the sixties..........does wonders on ancients.

Dang Ken, I thought we were contemporaries.........

 

Thad , stop by more often!! Hope all is well , Jim

 

Duh..."Brusha brusha brusha here's the new Ipana, with the brand new flavor, it's dandy for your teeeeeeeeeeth" From memory, now I'll look for the clip.

 

Green is a lot younger than us Kentucky...guess that's why he dances to the new music

 

Yeah, 5-6 years.

 

I think you just explained something to me. I bought two ancient coins at a pawn shop about 20 years ago. They both have the shiny finish like your after pics. I always thought it was because mine are probably fake. I was never too concerned about that, though, because I only paid 50 cents apiece for them. Now I think it's possible they are real. I'm going to have to take them to a dealer and find out.

 

Here is a pic of my two ancients. Anyone got an opinion on whether they're real, considering 20 years ago I only paid 50 cents apiece for them?

 

I have no idea abut the Asian coin since I don't collect them, but I believe the Carisius denarius is fake. Post a larger image to be certain.

 

Better?

 

The Asian piece is a Chinese Ban Liang, but I really cant see much in the photo.

 

It's a bit too fuzzy; however this type has been faked extensively. Take a look here: forumancientcoins.com/fakes under Carisius

 

And yet there isn't a warning about Benzene on gas pumps, where levels of Benzene can be as high as 1% during the winter.

 

What about Blue Ribbon, a favorite of the Early American Copper people?

 

After all the times we have discussed this one here, everyone on CT should have memorized the off center obverse with pit on the left edge and cheek here. Most recently, we saw one of these common fakes in an NGC slab and many here raked NGC over the coals for that mistake. I suspect they slabbed it years ago before this fake was quite so well known. My example was sold and refunded by a dealer who should have known better to me who should have known better but used it as a learning experience. Casts allow being doctored up to make them look a little different but this is a case where I believe we might be forgiven declaring any coin of this type off center to the lower right to be guilty until proven innocent.

 

Well now I know for sure. But I'm new to the site so I have never seen any other posts about this, and I only have a few ancients; most of my collection is American coins. I never really thought those two coins were real, anyway. Thanks.
