queching

[bradrobert]

new to this forum and the way it works. I'm about to quench a 1095 knife I made and was going to use water first for 3 seconds then oil? Saw this used on youtube.
Was hoping to get some feed back. Also I'd like to post an image of my blade but can't figure out how to upload image?

some time this week I will be quenching my first blade. 1095 steel. I'm using refractory cement and was going to quench in water for 3 seconds and then oil for rest. Saw this used on youtube...I guess its supposed to increase chances of steel surviving while keeping the hamon active. Also I'm new to this forum and would like to upload a photo of blade? Any thoughts on my blade or uploading?

I have done this with very good results. But I would use a brine quench instead its even faster. Make sure you practice with a cold blade and empty buckets so you can get the timing down

I will most likely stick with the heated water. I'll drop a red hot piece of steel in water and oil to raise temp before I drop my blade in.

Brine? as in add salt to water? never heard of this. Why do this?

Salt raises the boiling point which reduces the vapor jacket somewhat during the first few seconds of quenching, allowing slightly faster and more even cooling.

It is also less violent when the hot blade goes in. One 26oz box of salt makes two gallons brine. I use sea salt or Kosher for purity.

When people say "Water Quench" it really means "Brine Quench".
You dissolve 3# of rock salt in five gallons of water.

No shit... I am tempted to use this method then. I wonder if the ancient blacksmiths used this?

Don't know about that but it's all about reducing the chances of getting a cracked blade. I have done a few this way and I am thinking of doing the next batch in the brine. I just got to afraid of loosing all the hard work due to cracking. While we are on the subject of water quenching what can we do to reduce chances. Should you try to go up higher in the grits and reduce deep scratches and what other tips would someone want to practice.
