Foundry - Refractory materials as catalyst?

[Xynariz]

For Refractory recipes - is it intended to get the refactory ingredients back (or a chance for them, anyways) as part of the productivity bonus? Looking at the iron example in my K2SE game, I don't think I'm able to turn the process net-positive for graphite and silica, but I can lower it to 20 plates per graphite/silica.

Baseline (no enrichment, no vulcanite, no prod): 4.5 (silica/graphite) per yellow belt (15/sec) iron plate No prod, enrich, no vulcanite: 2.25 per yellow belt No prod, enrich, vulcanite: 1.5 per yellow belt (this is a 10:1 ratio - on average, I'll only need to use one silica/graphite per ten iron plates)

Productivity: No enrich, no vulcanite, T9 prod: 2.25 per yellow belt Enrich, no vulcanite, T9 prod: 1.125 per yellow belt Enrich, vulcanite, T9 prod: 0.75 per yellow belt (20:1 ratio)

Now I did have my iron jam because I got particularly "lucky" with a stretch of graphite/silica production, and that's just bad design on my part. But it led me to evaluate the refractory recipes in general, and left me curious.

Thank you. This is good feedback. I wasn't quite concerned about it, but I think you're right, given that it's probabilistic, I don't want to overcomplicate it. Also with modded furnaces and modules it might actually be possible to get a positive feedback loop, which is definitely not ideal or desired. I should update it so prod modules do not affect the refractory ingredients.

Possibly fixed in Foundry release 0.0.12

I believe this is fixed.
