- Visit our website for more free tutorials and jewelry-making resources! - fmg.co/m3ScFz Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals, copper, precious metals and aluminum alloys. In jewelry-making, pickling is completed after metal has been annealed. If you're a beginner metalsmith, you'll want to watch this video and our video on annealing that's in a link below.

Thanks! A lot of information in a short time. My main reason for commenting is about teaching safety habits. A teacher not following her own advice because "I just know I'm safe" seems a potentially dangerous method. I'd venture the guess that nearly everybody who ever hurt themselves soldering also "just knew" they were safe. I also have long hair that I know doesn't;t reach, but a ponytail-holder only takes a few seconds. Ditto for a hairnet.
Thank you Steve. We sincerely appreciate your feedback and will keep that in mind in the future. 🙂
Awesome tutorial. Thank you x
Glad it was helpful!
Thanks ...very informative!
Glad it was helpful!
Thank you.
You're welcome!
Do you think the crock pot lid is enough to keep the sparex fumes down, or should it still have a fan venting it outside?I know some work areas have exhausted and what not. I was just wondering what your thoughts were on it. I planned to just have a pot setup like that, but its just not a real good seal on top.
We would still recommend working in a well-ventilated area. You can refer to the Sparex Safety Data Sheet here: image1.fmgstatic.com/pdf/Sparex%20Pickle%20Compound%20No%201%20%20and%202%20-%20Rev.111915%20-%204549BS.pdf
And if i dip my copper tongs in the pickle than drop them in the quench which has baking soda in it than I dip ny copper tongs in the quench can i put then back in the pickle or will that neutralize the pickle
Dropping your tongs into the water dish is okay and it won't hurt the pickle.
I have a question that I can’t find an answer to, so I hope you can help. I make beaded jewelry with snake chain and crimp ends, but I want to transition into soldering ends. Is their a way to pickle, remove, or avoid fire scale without damaging the gemstones that are beaded onto the chain? Thanks.
Hmmm, that's a great question. We have never experimented with that so we can't say for sure what might work for you. Our apologies.
@@FireMountainGems Thanks for the reply. I really appreciate the honest answer, it’s so much better than getting no answer at all. ☺️
I’ll make sure to let you know if I find any info. Also, thanks for posting such great material, it’s been super helpful to me.
And easy gold solder paste where to find and what's the melting temp for easy solder paste gold?
How do you treat the pickle with baking soda to dispose of it?
And when I solder these jump rings the solder doesn't melt until it turns red like completely is that bad
Here is a link to our gold-colored solder paste: www.firemountaingems.com/itemdetails/h204768tl The flow point is 1250°F.
In the video you will see that there is baking soda added to the quenching bowl to neutralize the pickle from the piece before it is going to be worked on. As far as disposing of the pickle itself, please refer to the manufacturers safety data sheet on how to properly dispose of the product.
For the solder, it would depend on what you are using. Some solder has a much higher melting point. Be sure you are using the correct solder for that application.
@@FireMountainGems I just went on your website and saw that your are not requiring a license number to order stuff from your website
What would be best for removing firescale from steel?
Pickling the metal would help to start removing the firescale. After pickling wet or dry sanding and then using a polishing would help to shine up the piece! We have some great polishing supplies on our website: bit.ly/4bjHg7f
@@FireMountainGems Thank you
Hello I'm having trouble soldering these jump rings. I put them in the pickle the material is alloy steel/ brass. I put them in the pickle and they are still black. If they are fire stained what do I do? Should I make my pickle stronger? If the pickle needs to be stronger. What is the ratio for a stronger pickle? I don't want to make it to strong.
You will want to stick to the ratio provided in the mixing instructions for whatever pickling compound you are using. You can try leaving the metal in the pickle longer to see if there is any change over time. It may also help to polish the piece after pickling and then you can always return the piece to the pickle and repeat the process. It is also possible that the type of metal is not compatible with the pickle. Refer to the instructions on your pickling compound for a list of compatible metals. Hope this helps!
@@FireMountainGems thank you
@@FireMountainGems what are other pickle options for a alloy steel/brass jump ring?
No I'm using the spare x number 2 that you show being used in the RUclips video
The Sparex No. 2 is intended for non-ferrous metals, so the steel, which is a ferrous metal, could be the cause of the issue. We would recommend using a non-ferrous metal or precious metal. (brass, copper, silver, gold, etc.)
@@FireMountainGems ok thank you. What would I use to pickle the alloy steel/brass or any ferrous metal?
My pickle pot is small. How much sparex No 2 for a cup of water?
1/8 cup (2 Tablespoons) for one cup of water. Be sure to check the manufacturers mixing instructions before use.
@@FireMountainGems the mixing instructions say that the compound makes 24oz of water. It doesn't give a amount for a cup of water
I left my gold plated brass jump rings in sodium Bisulfate pickle which ratio was 1/8 cup of pickle to 1 cup of water and the jump rings came out black still. Can anyone tell me why this happened I have spent all day sanding the jump rings with 600 grit sand paper and than using the pro polish pad I'm halfway done I got two jump rings completely clean and the chain is halfway done
Pickle is meant to clear away the slag caused from soldering. You cannot solder plated metal. You can only solder uncoated metal.
@@FireMountainGems so in order to solder jump rings they jump rings have to be solid metal they cannot be plated?
Can u put nickel in the pickle?
Yes, this would be suitable for nickel as well.
Where i dispose of the pickle at?
It is recommended to dispose of the pickle solution at the nearest hazardous waste disposal site. Containers should be marked with the correct type of solution and metal, such as: "Sodium Bisulfate - contaminated with copper." Please refer to the Safety Data Sheet of the specific pickling solution you are using for proper disposal instructions.
