9:15 You could've just not done the decanting steps and instead directly wash the mercury sulfide in the vacuum filter with sodium sulfite. That way, you would get less mercury waste and less of a chance for yield loss from decanting.
Super interesting, and I am not here to eviscerate you but... not only were you not wearing gloves, I could see you wiping the cinnabar off your fingers. Looks like you were wearing a long sleeve sweater too. Dude you CAN be a tad safer. I saw the old beat up magnetic stirrer. I appreciate what you do and I understand you are on a shoestring budget but please wear gloves and goggles and a lab coat. A makeshift fume hood will work. You need that. I am sure you know who Nigel Braun is. He started at home too and that's cool but please do this so others will follow your example. Start off your video introducing yourself in a lab coat because that is cool. Put on googles and gloves and as needed and explain why. My thoughts. Keep at it and stay safe.
Mercury metal does not easily pass through intact skin, and it is perfectly safe to touch without gloves. Even if it did it would be very poorly absorbed as it's not much water soluble, nor really soluble in apolar solvents. Mercury sulfide is virtually completely insoluble in water, it has very low bioavailability and it is possibly the least toxic compound of mercury. It has been used as a pigment for centuries without much issue. The maximum allowed concentrations by law of mercury sulfide reported in the literature are so low only by analogy with other mercury II compounds and do not reflect any available pharmacotoxicological literature, as this is virtually non-existent. The only skin contact hazard I really see here is the potassium hydroxide which is highly caustic and corrosive, but still, it won't do much if you wash it off promptly. Don't get me wrong, gloves are important, but knowing what you are working with is much more important than gloves. Especially when there's people who use chemically incompatible gloves and/or don't change them after a spill of something dangerous by skin contact that will pass through them.
Except it would react in so many different ways with the poly sulfide, sulfite, and thiosulfate in solution as well as potentially reacting with some of the mercurial sulfide as well... probably best to not mess with the pH till the end
@@elirevzen418 I looked into it and found two patents I could scale down (industrial processes, processing 1000s of pounds at a time) and try one or both out. What do you want Cu2O for?
@@napalmholocaust9093 not sure, haven’t made a paint out of it yet. From what I’ve read about it and using this method to make it, it shouldn’t fade in sunlight. The presence of chloride is detrimental to how lightfast and generally stable it is, so using distilled water is necessary
You stated at the end you are open to suggestions for future videos... Something I have wanted to do for a while but can't seem to find literature on the topic is production of potassium nitrate. I have heard that one of the best sources is from bat guano and/or chicken shit. Almost everyone out here in the country has a chicken coop, and to say there are a LOT of abandoned hard rock gold mines in my area would be an understatement. A flat shovel, a backpack with a plastic liner yields copious amounts of black gold. So I guess what I'm trying to say is I have (nearly) unlimited access to the raw ingredients needed to make KNO3. However, the only literature I can find on the matter will show you how to prepare it for production, (basically how to make it easier for the chemist) but not how to actually make it! Talk about frustrating. If you were to make a video on that, you would earn my subscription, hands down.
Is there a reason that you don't like the many other youtube videos posted on that exact subject? I haven't watched them, as for me, KNO3 is easily cheaply bought. Maybe you haven't looked into it on youtube and have only searched for literature sources - regardless, if the other videos aren't satisfactory for your purposes, I could head to my local hardware store, buy a 25lb bag of "Chick N Poo™," which is apparently 100% chicken manure compost, and start working on something. Also, when you say black gold, what exactly do you mean?
It's a simple neutralization reaction, you react aqueous ammonia with hydroiodic acid. I needed some several years ago, and I made it by using a slight excess of ammonia solution, boiling it to dryness, and washing it with ethanol then filtering 3 times. After each ethanol wash and filtration, I pulled a vacuum on the product for 24h. Wrapping the flask containing the NH4I in aluminum foil is preferred because it's light sensitive. If that's an insufficient writeup, let me know, and I'll start working on a video shortly. I'm a visual learner, so I understand if a textual description isn't enough
The rubber over the vacuum filter is an awesome idea

8:24 What was the point of all the decanting when you could've just used the sulfite at the start?

I second this. Ppe is vital! Gloves, goggles and coat! Especially with mercury!
Plus look up how to dispose of these compounds

Awesome effort
At what temperature you heat the reaction?
Mercury is never safe in any form. Trust that. It can put u in hospital bed for 20 years, even throughlatex.
Amazing video ! Another mercury simple compound that has a stunning color is Mercury (II) Iodide, HgI2 also a redish orange color
اووك.ايش الفائده منه.اشتي اعرف
This is red Mercury sulphide???
Waiting for the obligatory "red mercury" comment...
Oh, look, there ^ it is!
Adding a small amount of HCl will greatly spead up the reaction of formation of HgS
Except it would react in so many different ways with the poly sulfide, sulfite, and thiosulfate in solution as well as potentially reacting with some of the mercurial sulfide as well... probably best to not mess with the pH till the end
How much heat we can give in machine
Does adding sodium hydroxide give the same effect like potassium hydroxide?
@@VR-qd8le yes
I've been looking for a synthesis of red copper oxide for years. Maybe you can make a video on that?
@@elirevzen418 I looked into it and found two patents I could scale down (industrial processes, processing 1000s of pounds at a time) and try one or both out. What do you want Cu2O for?
Super! Thank you very much!
would you sell this? if so how muych for 30 grams?
@@ps.6023 you can the same stuff from designated shops online easily unless you want mine specifically for some reason?
Does the color fade in sunlight over time as a paint?

Hi ! What's the temperature during the procedure? Is it a fixed temperature from the beginning to the end? Thanks!
Solution temp is around 45-50°C from beginning to end
How much heat we can give
U will do no bro
Please white phosphorus neuter liquid
@@sudhakarsudhakar1399 do you mean something to neutralize white phosphorus burns/exposure?

Can you plz melt 10 gram of this in furns?
It doesn't melt, it either sublimes and/or decomposes back into mercury and sulfur
Very very nice prosess
Super interesting.
Good working
Sir ap ka practical vee good but use simple language for other people. Thanks
Can I paint my car with this?
Very interesting!
