Fellow member & Knifemakers,

Here is a source for "Anti Scale Compound"
Rose Mill Company

PH: 1-860-289-4098

It is called "PBC Compound" it protects blade up to 1650F
Place your blade in oven or furnace at 450 degrees F take the blade
out and apply the PBC compound, place blade back in oven to harden
(Look at Rose web site for instructions) www.rosemill.com
5lb pail is approx $75.00 plus shipping cost.
This stuff is compatible with oil and water hardening and clean up is with water and brush..

They have another compound called "PBC Special " that protects blade from scale or decarb up to 2250- degrees F.
It cost about $125.00 per 5 lb pail.

Look at their web site for all the specs and order info.
It cost slightly less if you place an internet order.

They also offer a "Case color hardening compound:
Take a look at their web site, (Its kind of slow opening, be patient).
Good luck,
Mel Pardue

Hi Mel,
First of all Thank-you for the infomation, sincerely...

I did e-mail Ross Mill and asked them if PBC was for only up to 1650 F and/or could we use PBC Special for up to 2250 F.

Their response was if you are going up to 1650 F, PBC is the way to go. If you are going to take the HT to between 1650 to up to 2200 F, PBC Special is the way to go.....but alot of folks have variations of what they do....But before doing this with PBC Special, see Warren's post below on this thread....(edited to add reference to Warren's post)

Again, Thanks Mel....my wife who has a lot more common sense than me will appreciate your recommending this over that roll of foil I have in the shop...:D

Hey, Spend it like you can afford it!

Thanks again for being an asset of the Guild!!!!

Guys , Ive tried the high temp powder they supply & burnt up three blades doing it.The temp i used was about 1900 degrees & it just doesnt work. The low temp powder works fine. I called them on this & they could give me no explanation for the failure. The powder actually melted into the steel along the spine & the edge & I could not grind it out. Try it on a sample piece before you attempt a blade.

Warren,

Is it possible your temperature regulator/thermostat got really inaccurate at the higher temps; perhaps, you over-baked them…

My oven has two parometers which are calibrated correctly. I test & rockwell every blade & they come out to spec. Like i said, you'd better try it on a test block first!
