Obsidian.
The lava is pahoehoe Lava.
The smooth and shiny lava is called pahoehoe.
Obsidian.
Obsidian is a type of volcanic rock that is extremely vesicular and glassy in appearance. It forms when lava cools quickly with minimal crystal growth, resulting in a smooth texture and shiny appearance.

Pahoehoe
The rock you are describing is likely obsidian. Obsidian is a naturally occurring volcanic glass formed during rapid cooling of lava. It is usually black in color and has a smooth, glassy texture.
Yes that is why it makes that glassy look to it.
Obsidian.
Extruded lava.
The resulting texture of extremely rapid cooling of lava, where no crystals form, is known as glassy or obsidian texture. This type of texture is smooth, with no visible crystal structures, and can appear shiny or reflective. Glassy textures typically form when lava cools very quickly at the Earth's surface or in water.
Obsidian is a type of volcanic rock that is extremely vesicular and glassy in appearance. It forms when lava cools quickly with minimal crystal growth, resulting in a smooth texture and shiny appearance.
The resulting texture is called glassy. This texture forms when lava cools so quickly that no crystals have time to grow, resulting in a smooth, glass-like appearance.
Obsidian is an igneous rock that has a smooth glass-like texture. It is formed when lava cools rapidly without crystal formation, resulting in a glassy texture.
