    That's awesome, quick and easy. Do you save all of the test solutions and reprocess for the gold...ie...stock pot?

    • @omegageek64
      @omegageek64  ปีที่แล้ว +4

      Yes, I save the tests, but usually not in the stock pot. I try to keep it free of tin. I dump the tests in with my filters and rags.

    Mike, if you filtered the stannous chloride solution to remove the impurities, would it have a longer shelf life? And you'd eliminate / reduce the chance of those impurities eventually going into solution, diluting the stannous chloride.

    Excellent vid.
    Iv gotta say, though iv never criticised you for it, i hate the spoon method! Haha
    But you did just sell it to me. I appreciate the logic and will see what works best for me... probably a spoon.
    Heh.

    Does that mean tin tin should be made with tin metal?

    I have a question with the easy of making stannous test from fresh tin.
    What's your status on lab grade stannous crystal? Does that 5 dollar chemical supply crystal make Stannous Test the same as dissolving tin? Does it have a short shelf life living life as a "crystal stannouss" dry? And what's the recipe for a good test solution? Can it mix quicker than tin powder?
    All I could find online for mixing crystal staneous is add small amount of Stannous crystal to hcl. There is no info on the crystal Stannous and its behavior, being an undocumented science supply chemical.
    The test worked the day of for me. But I didn't know of expo on solution. After three weeks, back in the lab I never got a positive with my pure crystal made stannous solution, assuming know it was expired. Do you think my solution could have expired sooner, not using pure tin?

    • @omegageek64
      @omegageek64  ปีที่แล้ว +1

      I'm no expert in this area. I've only ever made it from pure tin or solder.

    • @NOFX0890
      @NOFX0890 ปีที่แล้ว +1

      Im no expert either. I have read:
      Potentially you are testing dirty, contaminated solutions, so a high purity tin is not of utmost importance.
      Some solutions will be highly contaminated depending on your material.
      Im planning to use lead free pewter and have read this is satisfactory.
      I Also save relatively clean tin (possibly gold/silver/ lead/soldermask + contamination) from BGA scrapping to test effectiveness.
      I Will take the residues undisolved by the HCl through a process to test for precious metals.
      If you have another use for high purity tin, i would save it for that.
      Great vid, great question.
      Appreciate the vid.

    • @NOFX0890
      @NOFX0890 ปีที่แล้ว +1

      Long winded, sorry.
      If its cheap and readily accessible the SnCl² crystals are a great option, I also came across a post that mentioned supplementing your solution with a small amount of undissolved Sn as a preservative.
      It might give you a slightly extended usage.
      If you test this, let us know!

  • @RolandoBustos-qc3hk
    @RolandoBustos-qc3hk 3 หลายเดือนก่อน

    Tin chloride is used to identify whether gold and platinum are present in a sample dissolved in aqua regia.
    I asked if the sample contains other elements such as iron, nickel and copper, which could interfere with the detection of gold and platinum.

  • @jerrydavis7130

    Hi Mike. Why it is important to use silver free tin? I though that silver will not dissolve in HCl.

    • @omegageek64
      @omegageek64  ปีที่แล้ว

      Waste of money and yet more sediment. If the silver percentage is high enough, the solder may not dissolve at all

    • @jerrydavis7130
      @jerrydavis7130 ปีที่แล้ว +2

      @@omegageek64 I use bga chips for making SnCl2 as you demonstrated ones. Bga suppose to contain about 10% of silver, so you strip Sn contamination from bga chips, sediment is mostly silver and SnCl2, after filtration is ready for testing of gold in solution. I like killing few flies with one swipe. Warning about solder containing silver is at the best confusing, but hey, I like your videos. Thumb up every time.

    Oh well. I bought tin shot before I saw this. I'm making my first batch of solution now. Based on current indications, the tin should be dissolved, and the solution should be ready in a month or three.

    I also use the same method to make stannous chloride solution, but the difference is I use waste solder which costs me nothing, then I keep the solution in the refrigerator, so the function will last almost forever.

    And i know it dont have a shelf life! Good for a month or two? So dont make alot. It doesn't take much unless you have a load of gold to test .

    How can you call this a "Stanous Chloride" test solution, without adding any "Stanous Chloride? Just curious.

    • @omegageek64
      @omegageek64  ปีที่แล้ว +4

      Um, tin plus HCl = stannous chloride.

    • @wadebert4458
      @wadebert4458 ปีที่แล้ว +1

      @@omegageek64 Um, TIN dissolved in HCL is not "Stanous Chloride". Granted it is the first step in creating Stanous Chloride. Your missing a few important steps, like evaporating the aqueous solution, until crystals of the dehydrated form, "Tin Salt" or Stanous Chloride. After this process, you rehydrate the concentrated, Stanous Chloride, with HCL and three nines fine Tin, to achieve a cohesive PGM testing solution.
      Three eggs, butter and cheese, don't make an omelet. You have to add heat, salt pepper, or you end up with a nasty mess, that, well. I guess you could eat; but, it wouldn't be an omelet.
      Usually, shortcuts, just end up getting you lost, or worse. If folks are wanting to test for Gold and PGMs, in solution, wouldn't you believe that it would be worth the extra effort to practice true chemistry, rather than risk a nonviable solution, that could cause someone to discard a solution that tested negative. Not because it lacked Gold or PGMs; but, rather, the testing solution they used wasn't what it should be.
      There's a reason why, "Chemistry", is called "Science". There are no shortcuts.
