Hi Michael

Hope Education list 250gms for £4.20 which seems a good price.

Sorry Michael, just read they will only deliver to a School address.

Hi,

Camlab is a UK chemical supplier who will happly sell chemicals to private individuals (as long as they are not restricted). They eventake PayPal. They list Sodium Nitrite at reasonable cost.

Unfortunatly it's on back order at the moment.

Try asking at a butcher

Michael, try these , no experience with Nexchem also look up Walsall chemicals they manufacture metal treatment salts which do contain said compound, I have used these folk for supplies. There is another one in Brum that supplied the gun trade— name escapes me right now but if the memory bank opens I’ll PM you

Not clear whether you want lab grade or food grade???

Before we went to all stainless pipework at work we used to have treatment baths for mild steel pipe fabrications. The first tank was deoxidine which was a phosphoric acid based chemical. The second tank was plain water to rinse off the deoxidine. The third tank was a heated tank containing sodium nitrite to neutralise any remaining acid and after the water flashed off left an anti-corrosion layer that was good for a week or so giving enough time to get the pipes painted then the bores were sprayed with preserving oil before the ends were capped off.

We went all stainless when the labour costs of removing lacquer, descaling (imagine the work involved with raised face spiral grooved ANSI flanges), treating and painting required for mild steel pipes outweighed the material cost of stainless pipes.

Important if you were going to pickle or preserve food

Sorry, typing too late, missed that bit.

Looks like it comes under Section 1.2 of This Document as a poison

So it looks like suppliers are taking the easy way out on EPP reporting and only selling to companies even for reportable substances.
In theory they should sell to the public and only report it if the transaction is suspicious. By only selling to companies they remove the need to judge if a transaction is suspicious. Basically they are applying the EPP prohibition to every chemical on the list They don't even say you can buy them if you have an EPP licence (you can't get an EPP licence for Sodium Nitrite becuse it not restricted DOH). The easy way out is to set up a business to use it.

If no luck elsewhere (and in no hurry) you might try adapting the time honoured 'saltpeter from urine' approach. Involves a pit. straw, chicken poo and urine and time. I seem to remember the result was boiled up and stewed with wood ash (potassium carbonate). Easy to substitute sodium carbonate (washing soda). The result is usually a mix of nitrate and nitrites. Best to wait till SWMBO is out….

Recall reading in some medieval gun history revival of some Dutch folk trying this out, the results a bit disappointing though. Perhaps some good English pee will do the trick. Other recipes are available.
