Hello! I've been looking into your mod and I'm liking what I'm seeing, but I am noticing that in my current mod-pack set up, it cannot really stand out amongst the other options, leading to my suggestion of possibly adding config options for changing the stats of the building? Most notably the Base Productivity, since it's +15% is quite weak/doesn't match the +50% of most Space age buildings.
In my mod pack for instance, the only thing it is the best at making is Heavy Glass, due to no other machines that can craft it having base productivity, Maraxsis' Reinforced Glass can be made with the Foundry, and mods like Calciner and Big Heat Furnace outclass it for the furnace smelted-glasses.
In my opinion, a hyper-specialized machine like this should be the best at its dedicated task. (or at least on par with more expensive/advanced options.)
