Elm Burling

I have been extremely lucky to find someone with an Alaskan Mill
to slab the burl for me, I cut off the bits that were sticking out and have started to cut them up and rough out some bowls, one piece that  was protruding was the remains of the trunk.
I didn't have to push the chainsaw mill so it looked easy it was my job to put wedges in the back side and stop the piece already cut from dropping down.
We first cut the top flat that gave us a tapered piece then 2 at 100mm thick and 2 at 75mm thick all the rest was cut to 50mm thick and that was about 5 pieces so in all about 9 pieces and some bits, the good man who did the cutting took 2 for his efforts.
Now they are all sticked up in a pile drying, that is with 2 sticks between each slab to allow air to pass through and the drying to take place
I have been cutting up the bits and rough turning bowls, it is a learning experience, as I am turning them it is good to see the colour return but then quickly fades again as the surface water dries out.
I am unsure how much movement will occur during drying so have been leaving plenty of thickness, I have weighed each one and written on them the weight it has only been a few weeks and already I can tell the difference in weight.
The smaller ones seen here are what I cored from inside the bigger ones.
