03 Merapi material story
The supplied photographs support a straightforward product transformation story: large volcanic blocks, thinner natural pieces, then regular cut tiles. We keep the commercial claims separate from what the camera actually shows.

Origin and lot relationship require records beyond the photograph.

Actual thickness range and yield must be measured, not inferred.

Size, tolerance, surface, edge and acceptance rule belong in writing.

For this website, Merapi lava stone means the owner-supplied natural volcanic stone reference from the Merapi area of Yogyakarta, Indonesia, shown as raw blocks, thin irregular pieces and rectangular cut tiles.
Those names are used variably in the market. Do not rely on a trade name alone: confirm origin, material identity, colour range, texture, geometry and an approved sample for your order.
No fixed public size or thickness is claimed. Send the required dimensions, thickness and tolerances so feasibility can be confirmed in a written quotation.
MOQ depends on format, specification, packing, trial purpose and shipping route. It is confirmed after those variables are reviewed.
You can request a sample discussion. Availability, representativeness, size, fee, courier cost, timing and relationship to a future commercial lot require written confirmation.
Suitability cannot be decided from a photograph. The project, finish, water chemistry, installation design and applicable performance evidence must be reviewed by qualified parties.
