What’s a ‘Serial Review’? Instead of tackling a comprehensive review of four inks in one shot with the result that I’d probably never do it, I’m creating a review with smaller, bite-size chunks. I plan to add more parts of the overall review in the future, all in this thread. In future ‘episodes’ I plan to show writing examples with fountain pens (Japanese fines, most likely, and perhaps some flex nibs) and on different papers, examine each ink’s properties (flow, feathering, sheen, etc.) with some detail, color change over time, and compare with other iron gall inks I have. Episode 1: Background & First Impressions I have several PenBBS inks and inks from the Ostrich Flower series and I've been very happy with those products, with very few exceptions. I have been super-curious about inks that are not widely available outside of China and have been exploring various brands the past few months. The latest exploration is four Ostrich blue-blacks, supposedly all iron gall, made by the Tianjin Ostrich Ink, Co., an ink maker that has been in business since 1935: 223 (48 ml bottle) 313 (55 ml bottle) 553 (60 ml bottle) 903 ‘Tianjin Museum’(60 ml bottle) I’m not sure but I believe this may be the first non-Chinese review of these inks. Background I noticed Ostrich’s four blue-black inks online when researching their Flower series inks a couple years back. I wrote the company, asking which of their blue-blacks are iron gall. The somewhat vague initial response was, in part, “We have two types of blue black ink.” so I replied with the same question. This time, the response was “All blue black of ours are made of iron gall. Only the differences of formulations.” [sic] Many of their ‘normal’, workhorse writing inks – blues, blue-blacks, blacks, reds, and a green – have been available off and on from the Lazada and Shopee shopping sites here in Thailand. Lazada and Shopee are Amazon.com-like sites, with country-specific sites in many SE Asian countries (and I see that Shopee has spread to some South American countries plus Mexico & Poland). The price has been OK – while low, still a bit expensive for workhorse Chinese inks – and it wasn’t until recently that I saw prices that were low enough that my curiosity could be satisfied with minimal guilt about spending money on ink I really don’t need. I ordered from Lazada, here. (Link is not an affiliate link - I make no money.) The lower price bottles – 223, 313, & 553 – range from about $2.50 to $3.00 USD, with a fairly similar price per ml. 903 is about $5.25 USD, with a significantly higher price per ml than the others. The total for the four bottles shipped and after a small promotional discount was the equivalent of ~$13.25 USD - approximately $0.06 USD per ml, which is quite low (and with proportionally low guilt). You can find at least some of these inks on AliExpress, but at higher prices. I put in the order 7 days ago, the inks shipped from China, and they arrived today, which is a typical amount of time for goods purchased on Lazada and imported from China to arrive here. Since I live way out in the country, about as far away in Thailand from Bangkok as I possibly could, it typically takes an extra day or two. Packaging The boxes look ‘classic’, not cheap, with professional-looking labelling that is nothing like many of today’s ‘boutique’ inks. Same for the bottles, all of which are classic-looking stout, glass bottles that are unlikely to tip over. Each bottle has a single label. You might have noticed that there are emus rather than ostriches on the labelling. (While I do like the name ‘Ostrich Ink’, I think ‘Emu Ink’ has a better ring to it. That said, the Chinese word for emu is a bit drab …). 223 and 313, which have similar caps that come off with a mere 2/3 of a turn, were packaged in clear plastic, zip-lock bags inside their boxes. Packing was adequate - the boxes arrived with no damage and there was no leakage. Box Front & Back Box Top & Bottom Box Sides Bottle Front & Back Bottle Side & Top Odor Note: I have a slight cold so take these with a grain of salt, please: 223 – To my nose it is a pungent & sweet odor very similar to the smell of Hero 232, another Chinese iron gall blue-black ink. 313 – Not very pungent and sweeter than 223 but not as sweet as the Rohrer & Klingner iron galls, Salix and Scabiosa, and Pelikan 4001 blue-black, another iron gall ink. (These German-brand iron gall inks all smell like some kind of sweet liqueur, at least to me.) 553 – Same odor as 223. 903 – Supposed to be “teak” scented but my nose isn’t picking that up. The least pungent and most sweet of these four Ostrich inks. But not as sweet as the Germans. Enough Boring Stuff: On With the Show I pulled out a dip pen with a “1” nib, a glass pen, a piece of Kokuyo Campus loose-leaf paper (WCN-CLL1110 – I believe this might be the old version of Kokuyo’s Sarasara, their smoother paper. It’s a fairly creamy color.), and a Rhodia pad and went to town. You can see the results below. Mobile phone photos in indirect afternoon sunlight. (I believe I must have had Hero 232 on my mind …) Kokuyo Rhodia Color and Behavior on Paper: Initial Impressions Notice that 223, 313, & 553 look the same! My initial impression is that there might be some differences in flow between these three and then there’s the different odor of 553 but, given that the Ostrich rep indicated to me that there are two types of blue-blacks, it very well could be that they are pretty much the same. I’m confident we will find out more about this in a future episode of this serial. 903 is, however, very different. While much darker it seems much more a very rich blue than a blue-black. Not a stealth black, however. Note 903’s feathering, which is unacceptable on the Rhodia paper and a little on the Kokuyo. There’s also lots of bleed-through (not shown here) and 903 has a thicker line than the others, even with the glass pen. Don’t be quick to judge - the dip pen really lays on the ink, as can the glass pen. And, on initial impression, 903 has a quick flow. Again, we’ll see more about the feathering, bleed-through, etc. in a future episode. Fading I am writing this review episode about 3 hours after I used the ink and there is very little, if any, fading of the blue color in any of the inks. I think this may be quite different than the other iron gall inks that I have experience with. Hero 232 fades towards grey much more quickly, for instance. Sheen All these inks have visible rosey gold sheen, much more prominent on the Kokuyo than Rhodia, as expected. 903 has relatively much brighter sheen, which, unlike the others, seems to tend to spread out and make more of a halo effect. All the images below are from the Kokuyo example. 223 313 553 903 [Lighting conditions changed during the last photo.] Chromatography Just ‘poor man’s’ chromatography for this pilot episode: a drop of ink on a napkin. Again, 223, 313, & 553 look the same. Also, based on this rough chromatography, I believe there is a good chance that all these inks use a single dye. Water Solubility Iron gall inks have a reputation for permanence. About an hour after I finished writing the Rhodia sample I got a small paintbrush, repeatedly dipping it in water to keep it wet, and I brushed the large numbers written with the dip pen and all the glass pen writing. Only a slight bit of 223, 313, & 553’s dye is moved – pretty amazing. More of 903’s dye is moved by the water but plenty of the ink remains in place. Watch this thread for new Ostrich blue-black review episodes!

In case you were wondering about the scientific differences between Hero and Ostrich inks observable through scanning electron microscopy. https://www.sciencedirect.com/science/article/pii/S2211715620300035

Ostrich ink is a very very old name in ink manufacturing in China and last year they bring out their first ever set of color ink in the form of the " Flower Series " at 15ml ea. for a collection of 12 colors; I recently get hold of a set of this in the plain form ( there is also the same set but with gold glitter ). A lot of back and forth communique with the factory tech finally get me informed that while the ink is not marketed or intentionally designed for mixing it is none the less mixable. So I set out to do a sampling of the ink and the combo The combo will have to wait a bit later but I've shoot a sample of the ink as they are The text is written with a 3B pencil and the gray card is a Kodak 18% gray for those who know how to color balance it; the paper is Rhodia dot pad. I forget to put the name of one of the color, that one is termed y the Mfr " Withered Sakura "

Ostrich is the main brand used by the Tianjin Ink Factory in China, and the firm is the first manufacturer of fountain pen inks; the modern pigment ink is believed to be one of their innovations. Oddly enough, while the brand is Ostrich, the logo is an emu: but then in the Chinese language the same word refers to both creatures, I understand. As a friend was making a trip to Tianjin I certainly was persuasive enough to end up with a few bottles of Ostrich inks, the most interesting one is undoubtedly the 901 Green, apparently the only green ink in series production in China. I understand that there was a 111 Green as well but it's no longer listed, perhaps it was renamed 901 to fit into the 90x series: 901 Green, 902 Blue, 903 Blue-black, 906 Red, and 908 Carbon pigment. The packaging is not luxurious at all, and the cap seems to be quite prone to leakage, but the content does work quite well. Below is a picture of the very few greens in my possession. The paper is very basic Xerox printing paper, a Serwex with a dagger nib was used. Compared to the original, the image - as displayed on my calibrated monitor - shows the Toucan Bright Green a little too dark and the Sheaffer Skrip Green a bit too light. Generally speaking the 901 Green is very easy to get on with, flows nicely and gives decent intensity; it does not appear to shade though. Compared to the most common Skrip, it shows the latter as more towards turquoise/blue than green. In reality it is very close to Toucan Aqua but with a touch more pea green as if it's Toucan Aqua with half a step towards Toucan Bright Green. In other words, it is a green with a moderate dash of yellow in the brew, and in effect it's a very "green" sort of green; compared to it the Toucan Bright Green is a bit muddy, and the Toucan Aqua has started to make its way towards blue. While I am no ink collector I cannot be sure how it compares to other green inks. But judging it by its own merits, I would say it is one that I can live with easily: a nice shade that is very easy on the eyes. But I sure hope that the backroom boys at the factory will eventually do something about bottle caps: they're meant to keep the juice inside the bottle!
