Chondrules were molten droplets. What caused the melting is hotly debated (har). Chondrule textures reflect the extent of melting and rates of cooling. Porphyritic chondrules did not fully melt. Fine-grained porphyritic chondrules began cooling with many fine widely distributed unmelted mineral crystals. Coarse-grained porphyritic chondrules had fewer. Either type can contain larger grains that survived the melting episode and retain their original character. Here are some chondrules with relict grains.
