It worked for me. I still have blinding gaps in my knowledge of machine-mades, but it doesn`t bother me a bit. I bought a few small lots of machine-mades in the beginning, just to get a feel for them, but after that I only bought Individual marbles, considering my money better spent in that way. I really bought only Peltier, Akro, and Alley. And Champion Furnace Swirls when I could get them. I decided I wasn`t all that interested in other companies, just buying the occasional Vitro, Ravenswood,MK, Champion etc. that really appealed to me as individual marbles, not because they`d been made by a particular company. So I have some nice examples of other companies` marbles, but that`s about it. I doubt you`ll ever see me commenting in an ID post about any of them. That approach allowed me to buy more and nicer examples by the companies I was really interested in (including some decent CACs that I would not have otherwise been able to afford). And some nice contemporary glass artists` marbles. I`m happy and satisfied by that decision I made long ago. Besides, as an art historian, I know you can`t know everything about everything, but knowing a lot about a few things is fun!
And of course, over time, you do start to soak things up about other companies - I do read all the ID posts, no matter what they`re about . . . .
