# Lesson 1 Creating the molten slag

In this lesson, you create the nParticle object and output mesh that simulate molten slag. After adjusting the nParticles and the output mesh so the slag flows down the chute, you apply a texture to the mesh, which gives the surface the molten red-orange glow. You render single frames of the simulation to view its overall appearance.
