You're probably thinking of Drierite, little blue rocks of anhydrous calcium sulfate with cobalt chloride so that it turns pink/purple when wet.
magma
Try slow heating at a moderate temperature and store in a dessicator.
The type of rocks formed from existing rocks that have been squeezed and heated deep inside Earth's crust are called metamorphic rocks. This transformation occurs through a process known as metamorphism, which alters the mineral composition and structure of the original rocks, known as parent rocks. Common examples of metamorphic rocks include schist, gneiss, and marble.
They are called clastic sedimentary rocks.
The rocks formed when other types of rocks are changed by heat and pressure inside the Earth are called metamorphic rocks. This transformation occurs through a process known as metamorphism, which alters the mineral composition and texture of the original rock, known as the protolith. Common examples of metamorphic rocks include schist, gneiss, and marble, which can originate from shale, granite, and limestone, respectively.
Dessicator is an instrument used in labs and laboratory.
yes there are some rocks that are round called geodes these rocks are hollow on the inside and have crystals inside them
Rocks with crystals inside are called geodes. Geodes are formed when mineral-rich water seeps into cavities in rocks, depositing minerals that crystallize over time.

magma
A round rock with pretty crystals of some mineral in them is called a, "Geode" (jee-owed)
They can be inside some rocks, otherwise called a Geode, They often grow inside caves, and many other places
Try slow heating at a moderate temperature and store in a dessicator.
Igneous rock.
its called molton rock
Rocks in the sea are typically referred to as sea rocks or underwater rocks. They can also be called submerged rocks or marine rocks.
Igneous rocks that are formed deep inside earth are called intrusive igneous rocks. These rocks are created when magma cools over millions of years inside earth. As it is cools, elements combine and form minerals. Intrusive igneous rocks are usually identified because they have visible crystals.
