Default YELLOW sodium sulphite / sulfite

I'm about to run out of sodium sulphite / sulfite, so have been checking the prices.

One of the cheapest about only offered YELLOW sodium sulphite. I've looked it up, and it is a thing, but I was worried that it wasn't pure enough for photographic purposes, so bought my usual white powder at a couple of pounds more.

So, has anyone ever bought some of the yellow kind and then used it photographically? Was it OK?

I've just never heard of this before now.

I use sodium sulphite as the 2nd clearing bath for chrysotypes so this may not apply but I would be very wary of using the yellow variety in case it stained the paper. Maybe that's just being overly cautious and it would be good to know if the dilution is clear when using it.

If it's yellow, it has something else in it. Maybe the vendor could clarify. I've only ever had it white.

edit: a search suggests it's sodium sulphide, totally different!

No, it's definitely Sulphite / Sulfite!! Yes, you do get Sulfide in yellow as well, but check google and this link of pictures which shows yellow versions of both, although more of the Sulphide:

And on two of sellers pages:

I find it pays to shop around and generally find it's much cheaper at firstcall https://www.firstcall-photographic.c...ous-1-kg/p7153

Not sure what apc charge for p&p, though

Barry and Terry It's a very comprehensive list - in fact too comprehensive

It might be easier if I asked: What chemicals do they not stock such as Phenidone or Metol?

Thanks

Mike

I have re-read my post above and realise it may have been assumed it was simply a "funny" but it wasn't I was just unable to find the likes of Phenidone or Metol I may not be looking in the right place or it simply isn't stocked

So do they stock either of are there some common photo chems they don't stock?

Thanks

Mike
