Roxley Iron Clays (200 Count)

Product Information

I am a board game player. I am also now the self-appointed family curator of a fairly decent sized collection of games. When budget allows for new cardboard recruits, my default is to seek out a new full game. Sometimes it flexes to admit an expansion to a beloved shelf-veteran. But when I saw the Iron Clays, all rules went out of the window. They went straight onto our shared Christmas wish list! Iron Maidens K. Lagarec and D. G.

This original masterpiece was first published in 2008 and is widely regarded as one of the deepest, most replayable economic games everdesigned. Honestly, these Iron Clays really have opened my eyes. Previously resistant to investing in accessories, I am now actually looking for games with the worst cardboard counters just so that I can revel in superior counter smugness! If you are fed up with cardboard coins lowering your fun level, I highly recommend investing in Iron Clays. After all, stunning counters are for life, not just for Christmas! A. Manceau, D.

For the majority of the samples, the LCF significantly improved when an Fe( III)-containing clay mineral reference (SWy-2, containing 3 wt% Fe) was included as additional reference in the fits. Released Si from Syn-1 after 1 day equilibration between pH 6 and 10 amounted on average to ∼0.016 mmol Si per g clay compared to up to 8 times lower Si concentrations for anoxic sorption samples with Fe (see Fig. S6a and S7 †). This provides additional evidence that the released Si from Syn-1 was removed from solution upon addition of Fe, either by adsorption or incorporation into newly formed Fe phases. It has been suggested by Soltermann et al. 30 that Fe 2+ can be taken up by the clay minerals, leading to the formation of Fe-bearing clay minerals.

To investigate the sorption mechanism of Fe 2+ to Syn-1 by XAS further, an additional set of samples was prepared at pH 7 or 8 under anoxic conditions containing 5 g L −1 clay, 0.25 or 2.5 mM Fe 2+, and 50 mM CaCl 2. The high CaCl 2 concentration and pH values were selected to focus on sorption processes on edge surfaces, which are expected to dominate under these conditions. Furthermore, at pH < 8 the dissolved Fe 2+ concentrations in the suspensions were always below saturation with respect to Fe(OH) 2 (Table S1 †).

I know we could have opted for metal coins. There are plenty of sets which are both game specific and open to wider application (the Scythe set is a great example!). But I am not a big fan of the texture, smell, or sound of metal coins. The jingling and tinny clinking jangles my ND brain, and I never carry cash around with me for that reason. But that is personal preference, and I am entitled to emulate monarchic habits whenever I like (haha!).

If a game has great components, it can elevate the experience to something next-level. Sometimes it can even save one that has a few bumps in its design. Not often. But sometimes. On the other hand, if a game has poor components, then that’s a real knife-edge moment. Keep it despite the bargain-basement bits? Or lose it and seek something similar but better furnished?

Environmental significance Clay minerals are considered major sorbents in soils and sediments. However, their significance for the redox cycling of iron is still unclear. Under anoxic conditions, elevated concentrations of dissolved ferrous iron are observed. We demonstrate that at circumneutral to alkaline pH, surface-mediated oxidation of ferrous iron can occur under anoxic conditions in the presence of clays that are virtually free of structural iron. The retention of dissolved ferrous iron in the presence of clay minerals was evidenced to be mainly due to the formation of secondary Fe( II/ III) phases. Subsequent aeration led to the complete oxidation of iron. In contrast to surface precipitation, adsorption of dissolved iron by layered aluminosilicates plays a minor role in iron retention and does not protect ferrous iron from oxidation. A. Manceau, D.
