While there is no shortage of irrelevant details, the article is very light on relevant details. What prevents the factory from staying in business? Not enough orders? The French people supposedly love this glassware and orders pour in whenever the company is mentioned. They have the factory up and running, they have employees. The workers own the means of production, what could be better than that? Why do they need…
I guess they have the same problem that Superfest glass from the GDR had, the glasses just don't break often enough.
I use only borosilicate glass vessels for cooking, for storing food, for eating and for drinking (some from France, some from Czechia).
I have replaced some of them in order to have more optimized sizes and shapes for the ways I use them (even if the replaced vessels were still perfectly good), and I have some extra vessels kept in reserve for the very unlikely case when I will break a vessel (which has not happened yet).
I do not expect that I would need to buy any more such vessels during my lifetime, unless I will become bored of those that I have and I would want a change.
So making money from selling high-quality glassware that can last forever is much more difficult than getting free money from a software subscription.
