not high enough high fire

A friend gave me a 12" steel ring about a 1/2" in height . I lined it with fiber paper and filled in my glass and fired 450 dph to 1550 hold 140 min
ramped down & annealed . I still have the small popped bubble look on top.
and this baby is thick
a tad over 1/4" I need to refire to loose the popped bubbles and add more color [to much clear] 250dph to 1600 / 1650?
some hold times in here? and to make a short story long, how can I add a rim + clear blank when this dang thing is already pretty hefty. can you thin down a blank without having it all over your kiln? and would kiln wash not fiber paper make the edges not so spiky... I did keep it away almost 1/2" from the edges and still got monster spikes... *sigh*
