Sintering has been used for years to manufacture porcelain. The differences however of porcelain vs. sintered stone are found when comparing characteristics.

While traditional ceramics might have one characteristic in common with sintered stone, no single ceramic product possesses all of the characteristics, including stain, scratch, chemical, and heat resistance that sintered stone does. 


How is Sintered Stone Made?

Sintered stone is a fairly new product on the market manufactured using recent technological advancements that weren’t possible before. Minerals and stone particles are carefully selected and ground to a powder which is then bonded together without any need for resins and bonding agents - but rather by using extreme heat and pressure to form a 100% natural stone.

Franke Stone Surface by Lapitec® is sintered at 1200°C with no resin or hydrocarbon based binder components. It’s chemistry and mineralogy is similar to granite but with a tight, cryptocrystalline structure and will also not emit toxic fumes into the environment when exposed to fire or extremely high temperatures making it a favourable choice for Green building projects.

The nature of Sintered Stone:

Franke Stone Surface by Lapitec® is full bodied being completely coloured throughout. This premium stone surface is anti-bacterial, stain resistant, scratch resistant, as well as heat and frost resistant.

It is ideal for application in the kitchen, bathrooms, fireplaces, large floor areas, as well as indoor and outdoor cladding and facades. And being UV stable it will not fade or yellow like other materials! Resistant to hostile environments and to corrosion by saline substances, the material is absolutely suitable for all surfaces that can embellish wet areas such as pools, yachts, spas and saunas.

Sintered Stone is the product architecture has been waiting for!



Why Sintered Stone has become so popular:

Sintered Stone is like no other product on the market today and there has been rapid demand since its introduction for both residential and commercial projects. Since Franke’s launch of their Stone Surface by Lapitec® in South Africa in 2017, the stylish Italian stone has been heralded by local fabricators as inspirational.

What makes this engineered stone such a popular choice is its far superior performance to that of Quartz and Granite.  Sintered Stone is strong yet light; it’s hard wearing, mould resistant, antibacterial, impervious to UV rays and scratch resistant. It is also non-porous so inherently very hygienic, easy to maintain and available in slip resistant finishes.

Another factor in its popularity is the increased consumer demand for thinner and larger format surfaces. Franke Stone Surface by Lapitec® is able to offer the largest sintered stone slab available on the market at 5, 05 m2 per slab.

Porcelain manufactures are now too offering larger format tiles to meet the growing trend. Porcelain however is brittle in nature unlike sintered stone which is designed for surface application. Franke’s slabs are a mere 12mm in thickness while extremely hard and impact resistant.  With a specific weight of just 2.4kg/dm3, Franke Stone Surface by Lapitec® is one of the lightest cladding products of its type available.



In October 2018 Lapitec® full-body sintered stone was awarded the title of “Innovative Material” at the Iconic Award: Innovative Architecture prize, an independent, international architecture and design contest founded by the German Design Council. The Lapitec® sintered stone surface was recognised being a sustainable material that is energy efficient and multi-functional by design.
