I love screen melts

So back from Florida, we had a great time, and I am once again looking at screen melts.  Following instructions in an e-book downloaded from Helios Kiln Glass Studio on Fused Glass Mesh & Trough Melts, I created the below piece of glass. 

The picture is a bit distorted, on its side, but the glass itself came out ok, unfortunately filled with black specs from the iron screen and a little uneven but good overall.  I am now fire polishing it to see if I can get rids of some of the little glass mountains on the top and smooth it out.  To fire polish I used the following firing schedule:

150dph.............................1000 degrees........................hold 30mins
Full...................................1400 degrees........................0 mins
Full.....................................900 degrees........................hold 60 mins
50dph..................................800 degrees........................0 min
100dph.................................725degrees........................0 min
0ff

So the fire polishing did not a huge job but I suppose that is a good thing.  There was a small rise or bump on the top of the piece and it somewhat modified that but it is still there.  Now I am going to slump it with the following firing schedule:

150dph.........................................1000 degrees.................................30mins
100dph..........................................1200 degrees..................................5mins
Full..................................................900 degrees.................................60mins
50..dph............................................800 degrees..................................0.
100 dph...........................................725degrees....................................0.
Off

There are several issues that I will be looking at here.  This slumping schedule, is quite different from the standard slumping schedule suggested by Bullseye.  I increased the 2nd step hold time to 5 minutes instead of 3 mins because it is a deep mold, but all of the slumping of the glass may have been taken care of in the hold time for step one which is 30 mins.  The other consideration is the unevenness of the piece itself.  Will that cause the finished piece to be unbalanced.  I bet it will.  Should I have put a border around it like discussed in the e-book.  I will look at that again and finally what about the black flecks and the little bump on the top.  What do I think about all those imperfections.
