@Carlos8400 and others were saying how they have not been able to re,ove the yellow staining on the bowl with usual hardcore measures.
Like I say, all I did was put clean glass housing into a clear glass joint. The bubbler was the HOTTEST bubbler I ever touched!
The hea5 level from the Ti that transfers to the glass is phenomenal. By whatever mechanism, there must be some high temperature alteration to the glass' surface, whether permanent or just a real bi$ch to remove, Im not sure.
But no chance was it macining oils or anything.
Besides, it really is no real concern. If it cant be helped, and everythihg still works, nomproblem really.
2 loads in the Ti today plus a vapcap. Even tried setting 6, was a bit harsh for me,,went down to 5.5 to finish a decent bowl to very dark brown.
It is the way the vapor suddenly comes and builds up with such velocity!
You'll be sucking, watching, waiting, then there is a mass of it with no effort at all.
I need to test out the options, higher temps smaller load, and vice versa.
An incident earlier- pre-heating on 4, dropped in bowl for some minutes, went to load and ghe glass housing was stuck tight in the bowl. I carefull used some force,,and the housing came off the injector and stayed stuck in the bowl.
No damage done. I used a dust cloth to free the glass, didnt want to wait for cool down and re-heat. Then I used the dust cloth to replace the glass, EXCEPT- i touched the still hot heater with the dust cloth and it melted a little hole in it, onto the injector!
What a muppet! I had to turn it off and do a wipe clean etc then a burnoff.
All good, but watch out for that one guys!
I am about to try the bubbler with the Omnivap now, I have hih hopes for it to make the vapcap a far more enjoyable experience!
