I have had the same problem with VanSon rubber base ink. I have a one
lb. can that was never opened during the year I had it, and it is
already much thicker. The local dealer has no explanation. Since I
don't use much ink, and it must be durable for long periods of time, I
can't afford to use rubber base ink.
