ClinkerChunk™ (1/2–1½ in)

ClinkerChunk™ is the boldest and most rugged grade in the ScoriaSupply line — large clinker fragments naturally forged in the intense heat of Wyoming’s ancient coal seam fires. Each chunk embodies the raw power of the Earth, featuring lightweight yet durable volcanic textures that make it perfect for decorative terrain, drainage bases, and structural layering in reptile habitats, aquariums, and terrariums.

With sizes ranging from 1/2–1 inch, ClinkerChunk™ delivers strong aeration and drainage, ideal for creating natural terrain height or separating soil and substrate layers in larger enclosures. Its dark reds, rusty browns, and subtle black tones bring an authentic, dramatic aesthetic to any display — whether you’re building a desert canyon for reptiles or a mountain base for aquascaping.
