Welcome back and welcome to all new subscribers! I am so happy to have you guys here!
I bought this pepper mill from a private guy. He told me that he had found it at the metal waste. Good guy, selling stuff from the metal waste 😄
You will see a lot of sanding brass on the lathe, lathe turning, cold bluing, vinegar bluing, wire brushing and more in this video!
If you are willing to support me feel free to leave a comment, subscribe and share my work!
I hope you will have some fun watching this video! If you have further questions on tools, my work or the chemistry behind the methods I use like cold bluing or removing rust, don’t hesitate to ask!

For experiments which could cause potential danger I will not tell you which chemicals I am using to prevent imitating. Those who know what is happening, know the chemicals anyway and probably are trained professionals. :)

@DrHutOfHandcraft 2 жыл бұрын

Hey mate, thank you for your comment! Of course you have to degrease the parts first. Cold bluing with vinegar is actually pretty simple (doesn't work with stainless steel): The acetic acid of the vinegar reacts with the iron and builds Iron (II) acetate. In this reaction hydrogen is also released. The reaction scheme goes like this: Fe + 2 CH3COOH --> Fe(CH3COOH)2 + H2 Iron (II) acetate makes the steel turn black. Btw Iron acetate is also the product which we receive when removing rust with acetic acid. In that case we brush it off, in this case we conserve it to stay. Heating of the vinegar is not necessary but it speeds up the reaction, since chemical reactions take place faster with higher temperatures. There is a rule of thumb which says that chemical reactions take place double to triple times faster when the temperature is raised for 10 Kelvin. The name of this equation is the 'Arrhenius equation', you can check that out if you are interested! If you want to try that out remember doing this only with a proper container, which is heat resistant. I used Borosilicate 3.3 glas. I hope my explanation was good enough. Let me know if you have further questions, I will be happy to answer them!

@@DrHutOfHandcraft Easiest way to answer this question is trying to grind coffee beans with this mill. If this works: it's a coffee mill for picknick or travelling (telltale sign: foldable crank) for one or two small cups of mocha á la Turka, which is the traditional way to brew coffee in all countries of the former Ottoman Empire. If not - because the entrance "holes" of the grinder are only big enough for the much smaller peppercorns: it's definitely a pepper mill. BTW: kudos for your marvelous work!

Hello again Jerome, thank you very much! So the cold bluing with vinegar is actually pretty simple (doesn't work with stainless steel): The acetic acid of the vinegar reacts with the iron in the steel and builds Iron (II) acetate. In this reaction hydrogen is also released. The reaction scheme goes like this: Fe + 2 CH3COOH --> Fe(CH3COO)2 + H2 Iron (II) acetate makes the steel turn black. Btw Iron acetate is also the product which we receive when removing rust with acetic acid, remember? In that case we brush it off, in this case we conserve it to stay. The heating of the vinegar is not necessary, but it speeds up the reaction, since chemical reactions take place faster with higher temperatures. There is a rule of thumb which says that chemical reactions take place double to triple times faster when the temperature is raised for 10 Kelvin. The name of this equation is the 'Arrhenius equation', you can check that out if you want! I hope my explanation was good enough. Let me know if you have further questions, I will be happy to answer them! Thanks again and greetings from Germany.

@@jeromebarois1875 Great question! The Iron II acetate on the rust removed parts is like only a top layer which is caused by the reaction, you can even clean it away with your finger, because it is also very loose. When bluing you have a degreased and clean part, which you put in the vinegar for some time (with heat) and the iron acetate layer is more durable. And of course you have to conserve it afterwards, if you don’t do that it would probably come of easily (like with other bluing methods). You could probably brush it away also, but I am pretty sure that this also works with regular bluing methods, like some quick bluing substances, since its only a thin and superficial protective layer. After all I think that this method should be as durable as other bluing methods if done right! 🙏🏼 Thanks a lot again for your support! 🙏🏼

@DrHutOfHandcraft 2 жыл бұрын

@@jeromebarois1875 Ah and I forgot: When removing rust with acetic acid there is of course also the rust (which of course is not only iron) which is included in the reaction. Basically the term “rust removing” is not 100 % scientifically accurate, since you are converting “the” rust into something else. With the bluing method we don’t have the rust taking place in the reaction. I am sure that this is also an important factor.
