    No, I didn't know about Utopian's technique then so the stone wasn't pre-heated. Well, accept that everything is preheated in the 90 degree + weather we've had for the past two weeks.

    All my Naniwa stones seem to be a lot more thirsty than the Shaptons.

    There are a lot of ways to manipulate the boiling temperature of a liquid.
    Clausius Clapeyron shows that the pressure of a system will change the fugacity of a liquid:




    It is also true, that a compound (liquid, or solid) that is less volatile and added to a volatile liquid (such as water) will increase or decrease the temperature said liquid will evaporate at:




    with dTsdp = difference in boiling Temperature
    Ke = ebullioscopic constant and b = molality
    (that´s how de-icing with salt works)


    So you either managed to decrease the boiling temperature of water by adding a special (so far unknown ^^) compound, or you completely evacuated the room you where honing in, causing dP to become extremely high and force the water molecules to evaporate.

    Or, and this is only my own opinion, the water did not evaporate,
    but got soaked into the stone, or run elsewhere.





    Sorry, I could not resist


    To add at least *some* thing usefull:
    There seems to be some difference in thirstyness in Naniwa.
    My SS1k, 2k, 3k, 5k and 10k seem to be less thirsty than my 8k,
    allthough, and this is interesting, my SS8k seemed not that thirsty for over a year and suddenly, it drank like a sailor
    (exaaggerated, of course, it still doesn´t require any soaking but 2 instead of 1 spritzer)

After looking at every vial in every box and cane in 4 tanks I finally had to report that the desired vials no longer seemed to be in the lab's possession. To me, the response was priceless..."well, just keep looking."
    Hey Ron,
    Looks like it's time for the lab to think about biorepository inventory tracking, management, and record keeping system. Look into CaTissue (this link give you some overview). It's a bit buggy, but does work very well. It's free and can be downloaded from NCI. I don't want to hijack the thread, but if interested, PM me.

    Thanks but that's not necessary. I'm only working in that lab on a temporary basis. They can clean up their own messes. I had no difficulties keeping track of everything in my own labs with my own databases but this is not my lab and so it's not my problem and not my place to correct. I just don't understand how someone can believe they can function in such a disorganized manner.

    No problem...It was just a suggestion

    Guys don't even joke about this. it's gonna be like breadknifing. Guys are going to see it and think it's just another routine honing method. Now they'll see this and start putting their hones in a 350F oven for an hour or two to enhance the effect.

    You guys are starting something and you'll have slurry and hone debris on your hands.

    You're right. I'm sorry. That was stupid. I didn't give a thought to the possibility that someone could take it seriously. I've edited my post.

    Holli started it.
