no. it does not matter if u start with 100 coal in the blast furnace. after 3-4 inventories of steel bars using coal bag + bucket of water, the blast furnace will run out of coal. Then every time the script empties coal bag and only gets 1 coal, but just did an inventory of iron, itll make an inventory of iron bars.
in short: steel bars + coal bag + buckets of water doesnt work properly. it makes like 1/3 or 1/2 of the bars as iron instead of steel no matter how much coal u start with in the begining i have even tried filling blast furance with as much coal as u can fit and then stating the script and it still ended up with a ton of iron bars
please fix and add silver bars aswell thanks
