# Basic Materials

<Color hex="#228">PneumaticCraft: Repressurized</Color> does not generate any extra ores in the ground. To get started, you just need *Iron Ingots*, which you will convert into *Compressed Iron Ingots*, used in many recipes throughout the mod.

To do this, throw your *Iron Ingots* on the ground, and cause a nearby explosion. *TNT* will do the trick, but any other explosion works too.

Warning: as a side effect of the explosion you will lose around 20% of your ingots. To avoid this, you can also craft *Compressed Iron Ingots* in a [Pressure Chamber](../manufacturing/pressure_chamber.md). However, to be able to craft the *Pressure Chamber* itself you'll need some *Compressed Iron Ingots*, so a little initial loss is unavoidable.

The *Block of Compressed Iron* is an excellent [Heat Conductor](./heat.md) and can be used to provide more faces to attach [Heat Sinks](../machines/heat_sink.md) to heat-producing machines. However, see also [Heat Pipes](../machines/heat_pipe.md).
