Yes, before machine made they were all hand gathered and machine rolled. I just posted the Sulphide thing for people who might not know how the earliest handmades were done before canes. I have a handful of 15/16ths or so pulls I got from a friend in the Netherlands.
It resembles a Veli, not seeing a single hand gather like a sulphide, single hand gathers were made from a single blob of glass. Big marble though, even for a Veli
