    Keten's price for Metol hasn't changed in the last two years, so the price increase seems to come from within Silverprint and does not indicate a global trend.
    Trying to be the best of whatever I am, even if what I am is no good.

    coffe-as developer
    citric acid-as a stop bath
    baking soda-asan accelerator
    salt- for HCAAND A MILD FIXER
    what else and for what
    ideallyI like to end up with all processing chemicals right out of the kitchen.Is that possible?
    Sodium thiosulphate (hypo) is sold as a food additive for cattle, so can be found in farmers' co-ops etc, much cheaper than as photochemical. Like sodium sulphite, it is used in a multitude of industrial and agricultural applications, such as leather tanning. So it is generally speaking very easy to obtain. Ammonium thiosulphate is somewhat harder to obtain, and more expensive.
    Sodium carbonate (washing soda) is sold in grocery stores.
    Vitamin C or sodium ascorbate is of course used in caffenol and related developers, and is sold in health food shops.
    Tartaric acid is used in some alternative processes, such as Van Dyke Brown.
    Sodium hydroxide is used in for instance Rodinal, and is sold as drain cleaner.
    Potassium metabisulphite is used in many formulas, including reducers and hypo-clear, and is sold as an additive in wine and also in preparation of dried fruit, so can be commonly found in farmers' co-ops.
    Paracetamol (aka acetaminophen) is the precursor to the active component in Parodinal, and is sold as pain killer (Tylenol).
    Potassium permanganate (used in some bleach formulas) is sold as disinfectant in grocery stores and pharmacies.
    Copper sulphate (blue vitriol; used in some bleach formulas) is also sold in pharmacies and grocery stores, mainly as fungicide.

    I think most will be surprised how many of the other photochemicals are also used as precursors or reagents in the manufacture of industrial organic compounds such as pharmaceuticals. Phenidone is one such example, as are the pyro compounds such as cathecol and pyrogallol. Many photochemicals are used for the same general purpose in industrial application as they are used in photography, i.e. as pH buffering (carbonates and borates) or chelating agents (EDTA) etc. For that reason they are not particularly hard to obtain via general chemical suppliers. An interesting chemical sometimes used in hair products, is amidol. It is however quite toxic and very expensive, and unfortunately short-lived. I have not yet purchased it via that avenue, as the shipping quantities are typically 25 kg. That will make an awful lot of paper developer. What makes such chemicals expensive is not the starting reagents or process per se, but the administrative overheads of dealing with and distributing hazardous chemicals, and providing proper safety measures etc, especially when international borders are crossed. I am sure you'd be able to buy it for $5/kg directly from the plant that produces it.

    The idea of developers such as caffenol or parodinal made from ingredients entirely available from grocery or hardware stores is rather charming. What is more, demonstrating how film can be developed with such lowly and commonly available materials really opens up some people (especially children) to the wonders of 'chemical photography'.

    The sarcastic edge in Pentaxuser's post eluded me, but that may be attributable to me being dense or not having had enough sleep. My own remark earlier was made tongue-in-cheek, so forgive me if you saw it as being personal. Some if not most of us are not native english speakers, and a lot gets lost or distorted in translation. Try to read without bias, otherwise it may seem hypocritical to protest at being attributed intentions you don't possess, while doing like to others. Or ignore whomever you wish - you are fully entitled to that also. I for one appreciate your presence on APUG, and hope you find a way to tolerate those posters that don't rub you quite the right way.

    This prompted me to check a few other bits and bobs: Hydroquinone, I paid £9.76 for 250g in May 2013, today it is priced at £9.36/100g (or £23.40/250g); Phenidone 25g, £7.85 (last May, £4.88); Sodium Carbonate £10.10/1.5Kg (£5.40 last August).

    I'm not suggesting Silverprint are "trying it on" - I just think it goes to show how how niche (and therefore expensive to acquire) photochemicals are becoming over here.

    Couple that with the fact that you can no longer buy metaborate from them, and more recently that they seem to have dropped CD-3 and CD-4 and I begin to wonder for how much longer we'll be able to buy raw chemicals like this in the UK. Silverprint are one of the few places raw developing agents can be bought in the UK (yes, I know we can buy from Moersch, but shipping is ridiculous and they've never answered any of my enquiry emails to them anyway)

    just a blurt and steam-letting-off really.
    Search on eBay. Hydroquinone, Photo Grade - 300g works out at £22.12 including postage to UK.

    The last batch of Catechol I bought came from Poland, including postage it was half the price it would be from UK sources.

    pdeeh, I felt you seem to have concluded that by and large Silverprint is not exploiting its position and you may be right. I then suggested that you contact Silverprint to find out its reasons for the large price increases which will give you a better position from which to draw conclusions and inform us as well.

    I tend to the view that if a supplier believes itself to have a monopoly position or more monopolistic position it is likely to increase prices but you may not take this view as is your prerogative.

    If the price rises are beyond Silverprints control then it seems to me that there is little if anything further to be said on the subject. "Things are what they are" to use my words in my previous post.

    If you wish to ignore my posts in future that also is your prerogative but I was simply trying to reflect what I thought your position was on the price increases which were big enough to persuade you to put pen to paper with a view, I thought, to getting others' views.

    At the risk of enraging you further I would just point you to a post after mine which suggests that Silverprint's position may not be the same as other suppliers in terms of the price rises and may not reflect a economic trend

    Having used up the last of my metol stock, I am also in need of ordering more. Checked out some of the supplies that claim "if you need it, we can supply it" to no avail. Just had a response from Rose Chemicals in London with a price of £12.50+VAT for 100g and P&P at £6.50+VAT - Compared to Silverprint's price of £18.96/100g (inc VAT), it looks cheap, but then it is easy enough to get a big enough order together to qualify for free shipping from Silverprint.

    A moot point as I've already ordered 200g for £19.00 (inc P&P and VAT) from an ebay supplier.

    One of the dangers of not keeping up with current events - Hadn't known about the current unrest in Ukraine.... If it doesn't turn up in a reasonable time, I have some protection via PayPal.

    Despite local disagreements within Ukraine, the package took just over a week to arrive - If anyone plans on following suit, get yourself some containers to store the stuff in. It get shipped in a well sealed plastic bag.
