01 / Geological family
Origin and composition
- Geological family
- Sedimentary
- Origin and composition
- Bioclastic limestone rich in foraminifera
- Origin
- Malta, mainly the south-western sector
- Appearance and identification
- Pale yellow and cream, often bioturbated
Sedimentary rocks form through accumulation, compaction and cementation of sediments, or precipitation of minerals. Sandstones, limestones and travertines belong to this broad family but have different compositions and structures. Visible bedding can influence slab design and cutting direction. Selection calls for attention to pores, cement, discontinuities and the specific product rather than assuming that every member behaves like one familiar stone.
02 / History and curiosities
History and curiosities
Valletta, Mdina and prehistoric temples document Malta’s long tradition of building and carving with this material.
03 / Applications and design
Applications and design
Applications include masonry, sculpture, mouldings and restoration.
Finishes and processes ↗04 / Technical interpretation
What to ask your supplier
Porosity, salts and exposure are decisive; historical use does not replace diagnosis of the specific material.
05 / Care and maintenance
Care and maintenance
Remove dust and grit with soft tools, wash with a compatible neutral cleaner, then rinse and dry. Identify composition before using stain or scale removers: carbonate stones are acid-sensitive. Test every treatment in an inconspicuous area. An impregnator can reduce absorption but does not make a material waterproof or stain-proof.
