NJSB W2 ht results

As a part of this whole ordeal I'm checking my oven for accuracy. It was suggested to melt table salt in my kiln (melting point 1475) as a way of checking this. I've read some conflicting opinions as to whether this is this a good idea.

I also just bought a K type thermocouple and PID from Auber Instruments. Is this a better way to check the accuracy?
I melt salt all the time, morton kosher no iodine. Melts at 1474°F. I forge small steel bowls and hang them in my furnance from hooks. Also I use a verticle drum forge to heat treat not kiln, dunno if salt is a safety hazard with heating elements but I have also done this test on an evenheat kiln. Not saying I recommend the later though

Yes, the Tempilaq Temperature Indicating Liquid is very accurate and correlates within 15 degrees with my baking oven and my Evenheat kiln at a wide range of temperatures. I've heat treated a wide variety of steels and measure the exact hardness I expect given known heat treat formulas. Hrc is not even a single point off.
 
Hey everyone, first off those micrographs are very cool, I'll be showing the guys at the shop. Next, I'll be hopefully posting up a bunch of AEIS results hopefully tomorrow along with some of our own results and samples sent out to other makers. We've fallen behind on the new website due to some things out of our control, but it will be up soon as well with mill certs, AEIS results, and suggested heat treats. So far in our internal tests we've had good results either going from straight stock to austenizing for 5 minutes per mm or 1550 normalize for 5 minutes per mm followed by austenizing for the same time. Hopefully I stated that correctly, I'm going to need to bug Warren and Ed and a few others before I put the results up so I don't sound like too much of a beginner. The only really anomalous result we had once we had the same two tests done to each sample I believe was .41 Vanadium in one piece. Other than that between both tests run on each sample things looked pretty solid. Most of the samples had two different tests run on them, but a couple I had them run the second test to check the carbon content. Maybe the guys here can shed some more light on it once I get them posted up. We sent a bunch of samples to the mill, the AEIS samples, tests results, and any other information we could get together. Also, the tip on the Temperature indicating liquid is a good one, had not heard of it before. Thanks for everything here, we're just trying to make sure we're staying on top of things as we can.
