Expanded Clay, Lightweight Expanded Clay Pebbles, leca, clay balls, clay pebbles is made from 100% natural clay at average 1200 degree in rotary kiln,

the Yielding gases are expanded by thousands of small bubbles as long as this temperature and porosity will appear by many voids and honeycombs

at these round shape aggregates when melted materials become cold.

Expanded clay

Our Expanded Clay is made of 100% natural clay,

lightweight Pebbles are uniform, round shape, inert, pH-neutral, and
decorative. Used in soil, hydroponics, and aquaponics Reusable,
High porous, Retains more water and moisture Many different sizes
of expanded clay can be offered Many different packing method can be offered
 
Physical Properties:
* Bulk Density: 230kg/m3 to 650kg/m3
