I think you missed my point. First off, the person giving the classes obviously doesn't teach boro, so it is moot. Personally, I use boro more than Moretti now, and though I have some teaching experience, I do not feel qualified to teach boro. Whether I can duplicate a given technique or not I can explain how just about any bead is made, if it is soft glass. I can't always do that with boro. Secondly, in my experience, most people taking a beginner class are unaware that there are different types of glasses, and as I said before are not going to go any further with it anyway. It's not that the teacher should care whether they go further with it or not, but running a boro class is more expensive. The glass costs more, the fuel costs are higher, etc. So either the class would cost more (which would deter students) or the studio would make less (which deters the studio). Then you would have the notion of having two beginning classes, one for boro and one for soft glass, which would only confuse the majority of neophytes. Also since boro works slower than soft glass, you can't cover as many basic techniques in a given space of time as you can with soft glass. While there are differences, glass is glass. Dots and lines are dots and lines and so forth. But boro presents additional things to worry about that soft glass doesn't. Knowledge of flame chemistry and multiple annealing temperatures and times for striking are not necessary in soft glass classes, but are important in boro. After having some experience watching people freak out over rotating a mandrel, I can see why a teacher would want to keep the info in a beginning class to a minimum. As far as a "cruel joke" because of "getting an intuition for the glass", that is highly unlikely to happen in a weekend or one week workshop anyway. At least for most people. Finally, having said all that, all I meant was I understood the studio's viewpoint, and tried to give reasons why. If a person is savvy enough about different types of glass to want to learn boro first or exclusively, there is no reason not to do so. Obviously, it would be to their advantage. After all pipemakers do it all the time. And if you found a place that taught boro at all, and you had enough people to commit to a class (whatever their minimum is), I'm sure you would, and should, be accommodated.
