I think I have this patina from my father. I thought it was liver of sulfur but it is written it sulfur and caustic soda. So this must be it. Unfortunately I have a lot of problems with it. I tried some of the online recommendation. I heat up the bronze sculpture, apply it, let it work for a while then wash it off and use a wire brush at the end. Some have told me to put it in a bicarbonated water and I’ve done that too. The thing is I end up with small dark stains on it and also with what looks like white salt flakes. I don’t know what to try anymore
When I worked with Sodium Hydroxide (Lye) to make soap we had a saying to remember how to combine it with water: It snows on the lake, it doesn't lake on the snow. As in Lye is the snow and the water is the lake...
Hi matey, could you do a quick edit and add eye protection to your list of essential equpiment please, I'd rate that more than every other safety part when you're working with boiling Lye!!
I do mine the extra stupid way, using a sealed container on a hot plate with a stir bar in it, which I do burp occasionally, that keeps the fumes and chances of flying drops of hot lye to a minimum, but introduces the fun fun fun risk of pressure building up too high in the container that could potentially go POP and spew it everywhere.. so I don't reccomend my method to anyone haha For everyone else, pretty please use eye protection!
If you noticed, I didn't even use gloves. I'm very familiar with lye. I used to make soap with my grandma since I was a kid. Off course, I will add a disclaimer in the description for those who don't know the behavior of sodium hydroxide. In this case I used a 1000ml beaker and 100ml of water. The wall of the beaker was very tall to prevent any plashing drop to go outside.
Risk is your second name… I don't even recommend the method that Jeweler Jordan does in one of his videos, where he put hot water in the mix of powders and everything goes like a frying wok. That's why I don't use eye protection, you just need to keep your face 25 inches away.
Thanks for the compliment (which you've edited, I liked that), and thank you for being present on my channel!!! I'm not sure about this method, but I've heard you can oxidize silver with bleach. I don't work with silver, so I've never tried it. You should experiment a little, and please tell me how it went, I'm really curious to know!!!
@@cuformingreally sry for that silly mistake, our dear super scientist sir I will definitely try this trick of yours☺️🌝 and also I have found a hack to oxidize my earrings with the boiled egg's yolk hack. Let's see whether these two are successful or not btw thanks a ton for the reply and idea . you r sharing very knowledgeable and interesting contents keep it up & all the best for ur alll experiment and for the bright future.👍🏻💚 Love from Rajasthan ❤️🙏
@@cuforming lol - me too! I'll be finding out in a week or so as I've just put your cold method of making Liver of Sulphate together. I will report back! Logic tells me that it's a possibility - after all, lead sulphate is pretty dark. It might well be good enough! Thanks again for your videos. Really really good stuff!
@@holymoly2353 Liver of sulfur on the market is usually made of potassium sulfide. The one I made is sodium sulfide and/or polysulfide (depending on the temperature). So, the reaction should produce lead sulfide, not sure. Anyway I've tested it on lead, and it does something, a light shade of gray appear but nothing extraordinary. On tin, it does nothing visible.
@@cuformingok, not terribly useful then... I suppose I could copper patinate and then use liver to darken it - or go to any or all of those colours! Could be fun! I'm dying to try but my solution hasn't even started changing colour yet... only 4.5 days left to go lol. Thanks for trying it out and letting us know!
@@holymoly2353 I know for sure that it works on copper and silver, and it does nothing on gold. It could work on copper alloys like brass and bronze. It'd be a nice experiment to test it on all kind of metals, or at least most of them.

Is it solid? Try to reboil a small piece, with a little water. And don't use bicarbonate to rinse, just water is good.

That's amazing! I wish I had a similar saying in my own language. Thanks for sharing, from now on I will always remember this when using lye.
Ahhh , need to try this
You should... and be careful!!!

Hey buddy give me any idea how to oxidised a silver jewelry at home and make it darker without using sulphur

Will this patinate lead and lead/tin solder too? Thanks for the video! Most useful...
I actually don't know... but now I need to find it out.

Does it work on silver?
Yes, it does
@@cuforming I mean to say sterling silver (925)?
@@LryuzakiLN Yes, It's good for silver alloys and copper alloys.
Not Liver of sulfur. Might be Sodium Sulfuret. Liver is potassium. Chemical dictionary is clear on this.
Sodium Polysulfide and Sodium Sulfide are the correct chemical terms for this substance. Just to be clear!
