Still in awe everytime I visit his site ... can't wait to one day just be able to watch much less take a class! Enjoy the eye candy!

And speaking of the master himself, I am going to be a wet blanket on "implosions." According to John Kobuki, the proper term is "COMPRESSIONS" as implosions are different. IMPLOSIONS are done with tubing. What we are doing with solid rods and the melting in, melting over, pressing, repeat... is compressing a design, NOT imploding it.

I took a class with John this fall and heard this from the master himself.

Granted, it's a losing battle to "change" our use of the term "implosion," but I do want this out there as my part in our educational process.

Just to add a bit more to the confusion, all the flower marbles I make are soft glass, the clear is Schott 91 which is much stiffer than the colours which are Bullseye, Kugler and Riechenbach ( lead free ) For reef marbles, galaxy, Vortex and Fumed I use Boro. The flower is much easier to make in soft glass and even though the colour is softer than the clear it "implodes" very easily and can be controlled throughout the process, also because of the intensity of the Kugler and Reichenbach colours it is possible to make the petals very thin without loosing the colour, what ever the process is, I'm certainly glad it works.
