Hi all I have a bottle of P de L which is about mmm maybe six years old. I haven't used it for ages, but had a sudden yearning but it's not really behaving very well in my TWSBI Eco 1.1. (The colour is to die for though.) It's not flowing at all well and I remember it being reasonably wet. So, it struck me that it may have gone off - any experience with this? I'd be sad to lose the bottle, but would definitely buy some more.
DevrimJan posted a topic in Fountain & Dip Pens - First StopTitle pretty self explanatory. I have heard that threads made of differing materials tend to have the softer threads wear out over time. I know that many pen companies do this with pretty much their entire line (such as Sailor with there metal section threads screwing into their resin/ebonite barrels). Others do it with particular models (like Visconti & OMAS with certain metal sectioned pens that screw into resin caps). Does this cause the softer material to wear out over time? Is this a poor design choice?
Sometimes I see pen auctions with 14k nibs that appear as if the usual iridium tipping has been worn down to nothing. The cost of retipping is often more than the cost of the pen, so am unlikely to pursue the better option for cheaper pens. With an untipped steel nib, I can pretty much grind it to a stub and expect it to last a long while. With more delicate gold, however, I'm not sure how long an untipped nib will be good for. Does anyone have experience with this? Will an untipped gold nib likely last a good while?
I have this obsession with ensuring that my possessions get the longest longevity possible, and since hearing things about threads getting worn down (especially metal to plastic ones) I have been wondering if threads on my pens, even plastic to plastic, would last longer with some lubrication. The answer would have obviously been yes, but then I heard that even silicone grease will weaken plastic with time. So yeah, should I lube up the threads or not, if long term longevity is what is desired? Also, how important is it that the silicone grease in question is 100%? Silicone grease is hard to come by where I am, and the one brand I was able to find was Polypipe. Anyone have any experiences with this brand? Are there any other kinds of lubrication that may be better than silicone?
