I bought a 1/2 Kg reel of Johnson Matthey silver solder from a gentleman (Mr Harvey) advertising on this site under 'Classified' - 'Miscellaneous' - what a bargain - £100 for what I have subsequently found would cost well over double that elsewhere. I know that he had one reel left. Highly recommended.

You'd better use it quick as after December the use of cadmium bearing solders is prohibited except for specific professional uses

Thought it was just the selling of it that was not allowed after that date.

Well with scrap sterling silver currently making £668 per kilo 1/2 kilo of easyflo which is 50% silver contains about £170 worth of silver so if it is easyflo bargain is the right word, I'll take 20 reels please.

From the EU press release:
 
"Cadmium is also present in brazing sticks, which are used to join dissimilar materials, and it is used for specific applications such as amateur modelling of steam engines of trains. Fumes released during the brazing process are highly dangerous if inhaled. The use of these brazing materials will be prohibited except for very specific professional uses."
 
 
Whether you choose to follow the new rules or not is up to you of course

what do you guys think of the Cad free solder . I have used it and find it poor to say the least ! it just doesent flow .The Quality of the joint worries me .I use this but hate it . My advice is to get the cad stuff while you can . I have been silver soldering in my trade for 30 plus years .I am finding this a backward step . I think it is a worry it makes the job so much harder

It is not an advert that I posted.....just an available bargain that I spotted and have brought to wider notice. I have no connection whatsoever with the seller other than as a satisfied purchaser.

Thanks for the references John Baguley. Just to pick out one choice morsel. Calculations suggest that there might be between 6 and 29 deaths which might be related to Cadmium Oxide poisoning, annually, throughout the 15 EU countries. (Yes, I know, that's 6 to 29 too many).
 
In my part of Lincolnshire there are more than 50 deaths caused annually by people being mown down by cars. God knows how many throughout the 15 EU countries. Statistically, I am sure that I am safer, silver soldering in my shed 24/7 than going for a walk down the lane!

The cadmium free solders do take a bit of getting used to. I've been using them for boiler making for a couple of years and had no real problems. You do need to be more careful with cleaning joints and need a bit more heat for it to flow properly. I do use Easyflo for some final joints and for small fittings etc. but won't be once my small stock is exhausted.
 
The main problem with the cadmium free solders is that they will be more expensive because they have a higher percentage of silver in the alloy. I agree it is a retrograde step for our uses but too late now. Some of us did complete a questionare from the EU to try and put forward our case but obviously it wasn't enough to sway the 'powers that be'
 
It is interesting that the main market for the cadmium bearing solders is/was model engineering - most of Industry stopped using it years ago.
 
Agreed you've got more chance of being run down by a bus or struck by lightening than getting cadmium poisoning, provided you take precautions e.g. work outside in the open. I did trawl through the actual EU documents and the main argument for the ban seems to be based on the high cost of the health care needed if anyone succumbs to the effects of cadmium

Who started the EU off on this particular track, cadmium has been banned from industrial plating for many  years.
 
Why the sudden interest in our silver solder use? Perhaps a vested interest (health interests aside)? Still available in the USA of course.

Hi Mark
I've just about used up all my Easyflo silver solder so recently I used some Silverflo rods,which I understand is the cadmium free alternative.I actually found this solder flowed very well with about the same heat input as for Easyflo,and found that the solder had penetrated the joints fully.
Granted,these were on some steel fabrications,which weren't overly big.
I've yet to find out how the new solder will work on brass or copper,or on fairly large fabrications;that might prove to be a different story!

Kwil....looking at some of the documents, it seems that the clowns in Brussels have been working on this for years and years and years. I suggest that the answer to your question is ....they had nothing better to do with themselves.
 
It beggars belief that they really want to save lives.....if that were the case there are dozens of more effective ways in all walks of life.

Stop worrying folks.
 
If anyone has some easyflo praying on their conscience, I will come around and dispose of it safely for a small fee

Hi all,
 
I took a silversmithing and jewellery making course at college for two years in the 1970's and had to use non cadmium silver solder on work pieces for assaying in order to qualify for hallmarking. I found no problem in use whether with sterling silver or copper fabrications as we used the same solder on both. As long as joints were well designed, accurately made, clean and well fluxed it worked well.
 
Regards
 
Terry
