Hi Jennifer,

you have all you need for basic soldering. As A pickle I prefer the really harmless pickle from 10% Alum-salt + 90% water, working temperature about 50 degree Celsius.

You can solder solder copper with silver solder also. The disadvantage is, that the solder seam looks silver-colored and is to see very clear. The advantage from silver solder on copper is, that the silver solder flows more easy than the copper solder.

If you use soldering-paste, you do not need no flux. Important is only, that the areas where the both pieces are in contact are really clean. You need flux only, if you are with silver-soldering-sheet or soldering wire working.

The terms soft, medium or hard of the silver solder is only a description of the working temperature. Soft means a low temperature, hard a higher melting temperature. The soldering seams have all the same solidity, equal if you solder with easy solder or extra hard solder.

Apart from that, soldering is just a matter of practice. Very important is, that the torch is not too small. If you do not get enough heat, it is impossible to make a good soldering job.

Normal 0 21 Most birds are very sensitive to carbon monoxide. Therefore, the miners still took until the 50's of the 20th century, one or more birds in the coal mines. When the bird fell dead, it was high time for the miners to leave the mine.
Carbon monoxide, however, should not arise on the proper use of a torch.

Re: Meco Midget torch w/ natural gas?

Hi Judie, I am so sorry- I meant no gas tanks. Yes,an oxygen tank in your home will still be needed. There is no difference here. The objective is to remove the gas out of the house for home owner insurance and for a higher level of safety. I called the company today and they said that at times when usage is high, it keeps the flow of gas steady without failure. Yes, perfect higher temps for casting, but perfect for all applications as well, according to them. Also, NYC had a number of accidents and this was a solution, now required if you are a jeweler in NYC, according to the website. Many great results if you can afford this, with no limitation on what you want to do, so it seems. What could be better than connecting to your gas line with a flashback connector at the meter. Although Oxygen is an explosive under certain conditions, under normal condition this would a relatively low risk and this is my objective. I had a fire in my home less than a year ago, NOT related to what I do. So it has left a lasting impression on me of what fire can do. I may be a little bit more cautious than others, but I don't have 25 years of experience to fall back on:) WISH I DID!!! Better to be safe than sorry. I just don't want to experience fire again. Kat

Hi,
The shown torch is deffinitiv too small. By using this you not getting enough heat.
Is there in the U.S. similar burner as shown here?

The 300-ml gas cartridge should not be dangerous in an apartment.

Meco Midget torch w/ natural gas?

Grisby — Fri, 30 Oct 2009 03:19:51 GMT

Hello,

I'm trying to set up a new Meco Midget torch to city gas. I've got the natural gas connected and it will light, but the flame keeps going out.

My idea was to use natural gas with compressed air...somewhere I read that was possible with this torch.

When I do manage to get the pure natural gas flame going fairly strong, when I add any air, it goes out immediately.

I'm wondering if I need an oxygen tank instead of just air. I think this is what they use at Revere jewelry school in SF.

If anyone has experience with this setup, I'd really appreciate hearing about it.

Thank you

Thank you for directing me to that page. I have a better understanding of why my piece isn't heating properly. Because of safety issues, at the moment I'm not able to bring a propane tank into my home. But I will try adjusting the flame with the larger butane torch I have. Here's a pic of the torch I use.

I'm going to give this a shot, hopefully I can get this torch to heat the piece properly.

Thanks again.

Hello Kat,

if you clean the soldering area well as you wrote and the solder don’t flow yet, the problem is, that your flame or torch is to small and you get not enough heat. Thereby it is regardless wheter you use silver or brass-solder with flux or whether you use a soldering paste which include the flux. Have a look to this page:

Here you find some more informations.

Hello,

if you want to solder jump rings, it is easier to work with soldering paste instead of soldering paillons. Soldering paste is much easier to dose I recommend low or medium melting paste. The paste include the flux, so that you need no flux. Use only a pinhead small amount of the paste. The seam of the ring must be so close together as possible!
If you want to work with paillons, pinch a very little piece between the jump ring seem.
What runs wrong in you first soldering?
I think you use a too big soldering paillon and you heated with a big flame the ring too much.
Look in this forum under Sea glass and soldering question You’ll find some more information.

Glueign irregular gemstone to a bezel. Help Please!

Starter — Wed, 02 Sep 2009 12:54:37 GMT

Hi, my first poject soldering was to bezel an irregular gemstone. Though it was challenging, it was a great experience.

When we were setting the stone, the teacher added a drop of glue to make sure some irregularities were tight. He didn't give me the type of glue or brand. can anyone recomend one, since I might be working with more irregular gemstones?

Thank you so much!

I appreciated the humour! We use the same term here for a small amount.

Well, it worked! I didn't suspend the piece in water, I just took the chance. So far, I have 4 of the 5 soldered and the 5th one is proving to be difficult! I'm about to pickle the piece, clean it up and give it another go. Once the entire piece is done and tidy I'll post a pic. I was thinking of using it for the August Theme-Summer, so I'll post the pic there.

I also fixed up that little baby bangle. I ended up cutting out the 'Y', resoldering the bangle and stamping in the 'I'. Very happy with the result.

Thank-you to everyone who contributed with ideas and suggestions, I'm very pleased that I worked up the courage to try this and whilst the piece is a bit unusual, I just wanted to see if I could do it.

Kelly.
