I cant seem to get my honeycombs to come out on 25mm ABR china tube. Silver yellows out bad, doesn't take the dots in well either, I've used both schott and chinese for the dots and its like they wont meld. You can see mass waves inside where the dots went in and I even had one where you could see/feel ripples on the surface where the dots were place. Couldn't polish it out for the life of me.

Then the comb itself doesnt want to take a very definite shape, its like the silver bleeds/blurs too much, yellows and I cant get any sort of blue crystal growth. I've had real bad problems with silver yellowing on the chinese tubing. Just wondering if it's me or if these are known issues. My next order is definitely some good ol simax.
