We will burn the metal with alkali so that the matte remains matte and the glossy glossy. In addition, bluing metal will be rust and scratch resistant.
To burn the metal with alkali, you need caustic sodium, it is also caustic soda, and sodium nitrate, it is also sodium nitrate.
We will bark with our own hands in a stainless steel container - another metal is not suitable.
Aluminum reacts violently to alkali. Enamel, like glass, albeit not immediately, but also corrodes the solution.
Therefore, look for a stainless steel. Bix is too small. And the barrels are just right. The height of the walls will not allow the boiling solution to fly in different directions.
We will degrease the first batch of axes by boiling, and we will burn the metal in a solution of sodium nitrate at the rate of 200 grams per liter of water and 600 grams of caustic soda per liter of water.
Degrease the second batch of axes with ordinary solvent. We will burn the metal in the same way in a solution of sodium nitrate, but increase the dose to 350 grams per liter of water and add caustic soda less than 500 grams per liter of water. I don’t know about you, but I’m wondering what the difference will be.
The smell when blued is quite pungent. Therefore, it is better to darken in the open air.
The first batch of axes was great. But there was one nuance when bluing metal with alkali.
The butcher's large ax cracked along the edge of the cutting edge.
The second batch of axes missed just super. There was almost no plaque, the gloss after bluing the metal with a larger portion of sodium nitrate looks better.
The little hatchet was the first to burrow with his own hands. The gloss is not expressive, and all in a touch. The butcher's ax was also the first to burrow. Plaque looks like rust, but not.
After polishing, bluing metal with alkali looked just super
At the final stage, he cut and sharpened the butcher's ax. The pure metal of the blade is striking, but overall it came out just super. Off-screen, he greased the axes with machine oil and wiped them dry.
And here's what happened. I like. If you like it too - put your thumbs up.
Let's take a closer look at the DIY result. The color of the ax is dark chocolate - almost black. The gloss is not much lighter. Colored sheen on gloss, this is an oil film. The gloss is even - no defects.
Cleaver. The pattern is also glossy. But the general view is spoiled by slag and other debris that remained after casting.
The next ax looks great. On the ax blade, where the hardened part is - the shade turned out to be slightly different. Closer to the plum. So the bluing color can be said also depends on the metal and the degree of hardening.
Small ax. Was defatted by boiling. The shade is darker, closer to black. It was not possible to polish the gloss well. But there was a wear effect. A kind of vintage style. And finally the butcher's ax. Yes. In some places the bluing was removed almost to the very metal. But the drawing began to look more expressive and rich. The ax is just super. The bluing of metal with alkali did him good .. It's a pity that there is no familiar butcher. The cutting edge against the general background is a little striking. But despite this, I am satisfied with the result.
In my opinion, the second bluing option is better. Slight plaque, good gloss, pleasant shade.
A few axes are going to work soon. After that I will definitely take a photo and post it in my groups. By the way, those who are subscribed to my VKontakte and Telegram groups are the first to know about new homemade products. The photo can be uploaded immediately. And the video takes time.
As for the bluing of the metal, the coating will be durable and moisture resistant, I have no doubt.
That's all dear friends. Now you know how to make bluing metal with your own hands .. The video was prepared for you by the author of the channel 1000 DIY's and Advice - 1000 DIY AND TIPS.
