medieval Posted December 14, 2008 Share Posted December 14, 2008 After tempering pieces I would like to protect and maintain the colors. I want to keep the bright blues and the violets. Clear coat does NOT work. I have tried several brands. At best it is hit or miss, and tends to wash out the blues and makes them brown. I saw some work at the local Saturday market, asked the guy about it, he just smiled and said it was a secret. So I know it can be done. :confused: Thanks for your help.

Dave Budd Posted December 14, 2008 Share Posted December 14, 2008 I just wipe them over with a bit of oil. something like danish or linseed oil hardens in air, so will leave a protective coating on the steel. I suspect waxes like renwax would also work don't forget that the oxides are very thin and rub off with use ;) Quote Link to comment Share on other sites More sharing options...
unkle spike Posted December 14, 2008 Share Posted December 14, 2008 I use Rustoleum "crystal clear" it doesn't seem to yellow like others, I wouldn't think it would affect the blueing or color of the metals. Quote Link to comment Share on other sites More sharing options...
jonathan king Posted December 17, 2008 Share Posted December 17, 2008 I use bees wax clear or dark wax i heat the metal up to straw or blue heat and apply the wax with a brush. I then cool the job then polish it up. but their are 101 finishes out their. Quote Link to comment Share on other sites More sharing options...
Frosty Posted December 18, 2008 Share Posted December 18, 2008 (edited) Temper colors are the result of oxide layers of differing depths depending on the temperature. The refracting layer is literally only molecules thick and applying a clear coat will alter the colors. Some more than others, some in predictable and compensable ways maybe eradicate them completely. The thinner the better, you might try super glue to start. Take notes and before and after pictures so you know what's what. You may not like an effect for one piece that will be perfect for another. Good luck, let us know what you find out.

Woodeye Posted December 18, 2008 Share Posted December 18, 2008 One of the best protective coats I have used on my knifes is Briwax. A couple of years ago there was a comparative article in Blade Magazine and Briwax far out performed the other materials - including renaissance wax, various oils and I don't remember what all else but the difference was significant. Give it a try! Quote Link to comment Share on other sites More sharing options...
