numbersix, don't let their use of water-glass complete turn you off from the company - as I noted originally, I was originally drawn to the company due to their Canadian origin - and didn't know sodium-silicate from grape-flavoured fish-shit when I started collecting them. However, even now, with a plethora of Stanwells, Petes, Chacoms, and even a few artesianal pieces at my disposal I wouldn't hesitate to snap up a new Brig if the shape catches my eye (most recently a little 1-dot straight-bulldog).
I do, however, take the time to remove the bowl-lining and thoroughly clean the pipe before I load her up for the first time. There may be better ways to go about it, but I have found that I get good results by tossing in a movie, loading up (another) bowl, and settling in with a sandpaper wrapped dowel for some serious wet sanding action.
Make sure you do this over newsprint, and afterwards ensure you clean the pipe (and yourself) up very well - the dust produced is rather caustic (as is sodium silicate in it's liquid form) and can cause skin irritation (and sinus/lung if you inhale the dust, half the reason I wet sand - the other half is better results).
