Lacquer to Prevent Tarnishing of Silver, Brass and Copper?  Discussion on Jewelry Making Journal

Hello. Can you tell me if it is safe to use a clear lacquer on jewelry for a more permanent solution to tarnishing of silver, bronze and copper?
Thank you,

  1. Hi Anne, thanks for asking! In this post – Product That Prevents Jewelry from Tarnishing? – people mentioned several specific products in the comments below the main post there. Hope this helps! 🙂

  2. Colleen says:

    I have been using Krylon non yellowing, gloss clear acrylic spray on my copper and aluminum pieces. So far I have had no probs with it and no complaints. Yes it’s a bit smelly at first, but the smell does go away. Hopes this helps.

  3. Hi Anne! I recently found a clear protective coating that prevents tarnishing on metals used to make jewelry. It’s called ProtectaClear. I just purchased a can online, and I hope to try it this weekend. I think it comes as a brush-on sealer and also as a spray. (I bought the spray version.) It has great reviews!

  4. Anne, I never use lacquer of any type on my copper, brass, or nickel-silver jewelry. If a piece was meant to hang on the wall, I might do it. But the wear that jewelry gets will eventually wear off parts of the lacquer, and it will develop an unattractive spotty look. Then all of the old lacquer will have to be removed (a thankless task!). I encourage my customers to wear rings 24/7, and doing the dishes and showering, etc., will keep them clean. For bracelets and pendants, oftentimes a silver polishing cloth will be enough.

  5. Like Ann, I also use ProtectaClear. I purchased the brush-on as I wanted to have pin-point application. I use it on copper blanks that I have flame-painted then hammered. It will work well on surfaces that are not constantly rubbing against another surface (won’t work on jump rings in weaves).

  6. Please keep in mind that any of the products mentioned need to be used in a well-ventilated area. Most of them contain toxic chemicals that you DON’T want to be breathing in.

  7. I have also heard of Renaissance wax. It is a paste. I have not used it long enough to know about it rubbing off. It is easy to apply and dries immediately.

  8. I personally prefer copper and brass in its natural state, but if you must seal, POR15 makes a clear coat catalyzed urethane that is terrific, VERY strong, especially in humid (body contact) environments. Not cheap but it is good for 15 years sun exposure. Negative: it is very tough to take off if needed. You can find it at automotive part supply stores and on Amazon.

    Incralac is a copper specific clear coat, good UV protection and can be removed with Methyl ethyl ketone (butanone), a solvent if needed. Not nearly as tough as the POR product above, but offers protection, easy removal if needed.

    Also, the POR product is a much thicker coating than the Incralac. Incralac was originally developed to be used for bronze sculpture that was outside.

    Also clear powder coating might be something to look at but sharp edges do not take good coverage, but this is true of most any applied material.

    Hope this helps!
