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.
Our Expanded Clay is made of 100% natural clay,
decorative. Used in soil, hydroponics, and aquaponics Reusable,
