Ok, first batch has 1780g when it should have 800g.
Therefore you have added 1780 / 800 more than you should have, =2.225
So, multiply all the other ingredients by 2.225 to get the same proportions in the glaze: -

feldspar 4000 g x 2.225 = 8900g
kaolin 1920 g x 2.225 = 4227.5g
dolomite 1280 g x 2.225 = 2848g
zircopax 600 g x 2.225 = 1335g
bone ash 640 g x 2.225 = 1424g
iron oxide 80 g x 2.225 = 178g

Likewise for the 4 other batches, you have added 1280g instead of 800g i.e. 1280 / 800 = 1.6
Therefore multiply everything else in the 2nd batch by 1.6 : -<

feldspar 4000 g x 1.6 = 6400g
kaolin 1920 g x 1.6 = 3040g
dolomite 1280 g x 1.6 = 2048g
zircopax 600 g x 1.6 = 960g
bone ash 640 g x 1.6 = 1024g
iron oxide 80 g x 1.6 = 128g

Hope that makes sense- feel free to check my calculations if you wish!
