Most things have increased copper, iron, oil and coal costs. But here is the comprehensive list of things with increased stone costs:
- Burner Mining Drill: 2 Stone Furnaces instead of 1
It would be consistent with other low-level components like iron gears, electronic circuits and pipes if stone bricks had their stone costs doubled. Maybe stone furnaces too since other basic items like inserters do have costs about doubled (due to gears and circuits). But anyway, just doubling the cost of stone bricks would also double the stone usage for concrete, advanced furnaces and production science packs. Whether there should be a quadrupling of cost as with electric mining drills is another matter but the stone brick change would be safe and conservative - and it still wouldn't put a dent in all the stone patches I've uncovered in the course of acquiring enough iron.
If it is desirable to maintain the balance of stone availability to paving the world with concrete, another point of doubling would be stone / stone brick consumption in furnaces.
