0:59 When I was a very young kid of only a few years old I got into the shed and tried to climb up onto the work bench. In doing so, I knocked over a bag or box of plaster of Paris and it fell right into my face and all over my body. It got right into my eyes and started rehydrating via my tears and my parents had to rush me to the ER. I don't remember anything other than being strapped tight in a straight jacket, hysterically losing my mind, as a nurse used a bag of saline and an IV tube to flush the plaster out of my eyes. :( My parents were traumatized. I'm lucky to have normal eyesight today. The shed remained locked at all times following that incident and I was officially deemed "a climber" and things were never kept on the countertops again. 😸 I hadn't done anything like that before, which was why I caught everyone off guard. Ok, thanks for stopping by to share this random traumatic memory with me. I have many more but they aren't relevant to plaster. 😇

You can try discharging capacitor to spot weld PT1000s. You will just have to make a several trials to see what kind of energy is needed to spot weld the wires, and then just charge some large caps to get it to enough energy (and hopefully not to vaporize a sensor). After initial runs, it behaves quite/ consistently afterwards. This copper foil connection will oxidize and it can start varying a temperature, making a mess of experiments. Good news is they are failing safely (increasing resistance equals increase in temperature) but lack of heat can be an issue...

You might have problems with the copper foils, each heating will cause them to expand. Then they change position slightly, and eventually they will lose the electrical contact. Since you do not have the ability to weld, you need to crimp the connectors. The most available are probably the smallest ones car mechanics use or bootlace ferrules. Just strip the plastic off if any. Is there any possible use for the residual products in the dry method?
@NurdRage4 жыл бұрын
Very true about the copper foil. I guess i'll just have to cross that bridge when i get there. I might see if i can electrochemically bond the connections if it gets really bad. That might be an interesting video it itself! As for the residues. I'm not really sure. I suppose if you filter it, you can get crude calcium sulfate powder. If you heat it up to dehydrate it you can make your own plaster powder. Also calcium sulfate powder can be used as a catalyst support (but i'm not sure if i'll get that far on my channel). If you mix it sodium carbonate solution and stir for a few days you can convert it to calcium carbonate which is useful as a base for other reactions. Personally though, for the amount of work and cost, it might be more straightforward just to buy those end products. But i'll see if there is enough interest to attempt a recycling effort.

I convert my calcium nitrate to the more desired nitrates (eg sodium nitrate by using soda ash). This forms sodium nitrate and Calcium Carbonate at pH~7 which is highly insoluble, easy to filter, not as voluminous as calcium sulfate, and useful for neutralizing other metal (iron, nickle, copper, etc) nitrate solutions to scavenge the nitrate ion as calcium nitrate again to repeat the process. Of course, once neutralized the excess water will need to be removed to concentrate the nitrate in solution for the highest strength nitric acid when using the wet processes. Doing it this way allows us to use the Ca++ ion as a nitrate source and scavenger for recycling metal nitrate solutions. I can buy Calcium nitrate plus soda ash cheaper than sodium nitrate excluding my labor costs of course.

I honestly feel the best choice when using calcium (ammonium) nitrate is to mix a solution of it with ammonium solution. it will form insoluble calcium hydroxide and ammonium nitrate. You can even use excess ammonium solution to ensure full conversion of the calcium salt then recapture the excess ammonia. it is a little extra work but it is much easier to make nitric acid with pure ammonium nitrate than calcium nitrate or the mixed salt. You can than easily form sodium/potassium nitrate with the appropriate alkali hydroxide. This can be done from the mixed salt too but you will always have either a calcium nitrate or alkali hydroxide impurity which could hinder some reactions. Yes you will have the same issue with pure ammonium nitrate but just use and excess of ammonium salt and the impurity will be guaranteed to be ammonium nitrate and not the alkali hydroxide. For most reactions a small ammonium nitrate impurity will not affect the reaction in the same way calcium nitrate or alkali hydroxides will. Also when drying the alkali nitrate a byproduct will be ammonia gas which can be recaptured helping replenish the supply you used in the initial reaction. Yes it is more work but you have a higher rate of success in your reactions, and you will not end up with nasty gypsum in your flask.
