Slumping botanical pattern mold and fighting Devitrification on smaller pattern mold

I continue to have a devit problem.  With the deeper pattern molds I have lowered the processing temperature and brought the hold tie way down low.  I can lower it even more and will try this when next I use the deep pattern mold.  But to begin today I am slumping an already completed piece.  I will use the following firing schedule:

200dph.............................1220 degrees.....................5 min
Full.....................................900 degrees.....................1 hour
100 dph...............................700 degrees....................Off

Once i finish slumping I am thinking of using the cherry blossom fuser again, with one layer of clear and then one layer of clear and red glass on top.  I changed my mind about using the red and clear glass.  Did another design of white mixed with a clear glass with red and brown and white stringers on it and I put clear glass as a base.  Thinking of full fusing the whole thing first and them putting it on the mold .  So I am full fusing layer of clear glass and another layer of several pieces(2pieces of white and one piece of clear with stringer glass) on the bottom.  I am placing it on the bottom to see if I can get a more fully fused piece with better lines.  Then after fusing I will put it on the cherry blossom mold and fuse that.

So I will be looking to see how the design and the mixture of the glass works when I put it on the bottom and full fuse it first.  Often when fusing a solid piece as the base and mixed pieces on top those pieces to not fit together very well and appear to have spaces.  Perhaps putting the mixed pieces on the bottom whilst fusing them will allow them to fit together better.  Tomorrow I will spray the cherry blossom pattern fuser and place the new double pieces fused today on top of it.  Lets hope it all works. 

New Mold 4 and 5/8 inches square.

I've got a new mold, a subtle slump, 4 and 5/8 inches square.  I think I will use this size (small) and the shape of the mold to practice more with design and color.  This way I will not be making big pieces and potentially wasting the glass, if it come out not the way I like.  This initial fuse with the dot design came out well>  Corners were rounded on this 2 layer piece of one 3mm blue opaque and one 2mm clear piece.  This combination of pieces equalling 5mm not the typically 6mm feels right, not too thick or heavy.  Also I had cut the rod into uneven pieces, not on purpose, but because it is hard to amke them all the same but they all fused flat and well but some appear to have a samll bit of devit on their tops, maybe a leftover bit of the glue that used to stick them to the surface before putting into the kiln.  Should i try to fix it with the fix of putting a layer of clear glass powder over the top and refiring it or should I go ahead with the slump?  I will think about it.  Anyway to fuse it I used the following schedule:

300dph..........................................1225 degrees......................................30 min
600dph..........................................1470 degrees.......................................10 min
Full..................................................900 degrees.........................................1 hour
100 dph...........................................700 degrees.........................................2 min
Full....................................................70 degrees.........................................Off

Anyway, I decided to put a layer of clear powder over the top surface and fire it to 1425 degrees and hold for 10 mins.  I ramped up 600 dph for the first and second step and then held at 1425 degrees and then full power to 700 and then off.  I hope this annealing does not break it.  I should go slower.

It did not break thank goodness and it also came out beautyfully, the devitrication on the dots was gone.  I love Bullseye, anyway, now I am slumping it with the following schedule:

300dph...................................1200 degrees....................hold 20 mins
Full............................................900 degrees...................hold 1 hour
100 dph......................................700 degrees...................hold 1 min
Full...............................................70 degrees...................Off
