About Padang TG35 Bianco Tarn

Padang TG35 Bianco Tarn shows a classic French building granite with a balanced salt-and-pepper look. The groundmass consists predominantly of pale whitish-grey plagioclase and potassium feldspar crystals, in which black biotite mineral dots are distributed with high contrast. The ratio of light to dark is roughly 65–75 % pale groundmass to 25–35 % black mineral dots — which produces an overall pale impression with a clearly legible crystalline structure. Characteristic are the medium-sized, clearly delimited black biotite mineral dots that give the pale groundmass a classic salt-and-pepper character. The mineral structure is isotropic (without direction). On a polished surface the stone develops a classic gloss with a clear legibility of the mineral structure.The TG35 code was historically carried by a German distributor within the 'Padang' product family, even though the stone itself is of French origin. The correct petrographic identity is BIANCO TARN or TARN GRIS from southern France. This confusion of trade names is a frequent phenomenon in the international stone trade — when ordering we recommend always specifying the full name 'Padang TG35 Bianco Tarn' or using the correct name 'Bianco Tarn' / 'Tarn Gris'.

Geologically the stone is a Carboniferous granite (about 300 million years old) from the Tarn département in southern France, a region near the city of Toulouse. The quarries lie in the Massif Central, one of the significant European granite complexes. Petrographically a medium- to coarse-grained plutonic rock with a balanced mineral distribution. The material is known under the trade names TARN GRIS, BIANCO TARN and CLAIR DU TARN. The stone is frequently used in Germany. Several synonyms are in circulation in international trade: Tarn Gris (the main French designation), Bianco Tarn (the Italian spelling variant — 'pale Tarn'), Clair du Tarn (French — 'the pale one from Tarn'), French Grey Granite and Granit du Tarn.

Technically Padang TG35 Bianco Tarn shows solid values: bulk density 2,700 kg/m³, compressive strength 171 MPa (very good), flexural strength 16.0 MPa, water absorption 0.34 % (low), porosity 0.41 %, Mohs hardness 6–7. Full frost and acid resistance is confirmed for it as a silicate rock — wine, lemon juice, vinegar or sanitary cleaners leave no etch marks as they would on marble or limestone. The stability of the polish outdoors is lasting. This makes Padang TG35 Bianco Tarn fully everyday-capable for the most demanding interior and exterior applications, including prestige exterior façades with the polish retained.

At ROSSITTIS we stock Padang TG35 Bianco Tarn as a raw slab in 20, 30 and 40 mm thickness (standard gauges plus solid applications for stairs or bar counters) and for project-specific cutting to size. The available standard finish is polished (a classic gloss with full depth).

Compared with other classic European white granites, Padang TG35 Bianco Tarn is a traditional French choice: Blanco Cristal Extra (a Spanish leucogranite from Cadalso de los Vidrios) is paler and more uniform; Mondariz Crema Julia (Galician) is warmer with creamier tones; Bianco Sardo (Italian) is coarser-grained; Padang Hell / G633 (Chinese) is the more price-attractive Asian alternative with a similar look. Within the French granite family, Bianco Tarn / Tarn Gris is the most widely used pale grade from southern France. For architectural projects with a classic European pale character — exterior façades on prestige buildings, classic floor areas, stairs, building applications in the European heritage tradition and conservation restorations in the French dimension stone tradition — Padang TG35 Bianco Tarn is a dependable and expressive choice within the pale French building granite range.

Finishes

Padang TG35 Bianco Tarn is available in a range of finishes. The finish affects appearance, feel and the care it needs.

Polished

Polishing is the most classic finish in the hard stone segment — a mirror-smooth, high-gloss surface with the highest possible colour intensity and maximum depth effect in the mineral structure. As an acid-resistant silicate stone, polished granite is easy to care for and the first choice for kitchen worktops, wall claddings and prestigious exposed surfaces.

Care & fabrication

As a French Carboniferous granite, Padang TG35 Bianco Tarn is a robust hard stone with low water absorption (0.34 %), full frost and acid resistance and very good mechanical strength. Wine, lemon juice, vinegar, cola, sanitary cleaners or descalers leave no etch marks as they would on marble or limestone — the stone is considerably easier to look after and ideally suited to intensive everyday use.

For interior applications we recommend a silane- or polysiloxane-based impregnation at first installation. On the pale groundmass, impregnation is worthwhile, because pigments can otherwise settle more visibly. On polished surfaces a refresh every 8–10 years is enough; on heavily used floor areas or in exterior applications, check every 3–5 years.

Day-to-day care is done with a pH-neutral natural stone cleaner and a soft cloth or microfibre mop. Clear warm water is usually enough. Acidic cleaners are in principle unproblematic, but should nevertheless not be used, because they can attack the impregnation. The surface finishes available from stock are listed in the »Finishes« block further down.

For kitchen worktops Padang TG35 Bianco Tarn is solidly suited: cut- and scratch-resistant (Mohs hardness 6–7), insensitive to heat (hot pots and pans can be set down directly for short periods, but longer heat exposure above 200 °C should still be avoided), acid-resistant and with good stain repellency. The pale salt-and-pepper surface does, however, show sauce, red wine or turmeric stains more strongly than dark granites — with intensive kitchen use you should react promptly.

For exterior applications Padang TG35 Bianco Tarn is particularly well qualified: the durability of the polish outdoors (durable outdoors) and the low water absorption make the stone a first choice for demanding exterior façades with the gloss retained. Polished exterior façades keep their brilliance for years. Its historical track record in German buildings confirms its long-term stability under weathering.

For pool surrounds, outdoor terraces and fountain enclosures, a slip-inhibiting textured finish is mandatory — on polished exterior surfaces there is a high risk of slipping when wet. In areas with frequent salt contact we recommend an additional impregnation refresh every 3 years.

What does 'Bianco Tarn' mean?

'Bianco Tarn' means 'pale Tarn' in Italian and identifies the paler grade of the French Tarn granite. The main name is 'Tarn Gris' (French: 'grey Tarn'); 'Bianco Tarn' and 'Clair du Tarn' (French: 'the pale one from Tarn') are the grade designations for the paler version. All three designations refer to the same French granite from the Tarn département.

Is Padang TG35 Bianco Tarn suitable for a kitchen worktop?

Yes, well suited. With Mohs hardness 6–7, low water absorption (0.34 %), good compressive strength (171 MPa) and full acid resistance, the stone is cut-, scratch- and heat-resistant and does not absorb the acids in wine, lemon or vinegar. The pale salt-and-pepper surface does, however, show sauce, red wine or turmeric stains more strongly than dark granites.

Which surface finishes are available for Padang TG35 Bianco Tarn?

The surface finishes available from stock are listed in the »Finishes« block on this page.

Is Padang TG35 Bianco Tarn suitable for exterior façades?

Outstandingly suited. The durability of the polish outdoors (durable outdoors), the low water absorption (0.34 %) and its historical track record in German buildings make the stone a first choice for demanding exterior façades with the gloss retained.

What does Padang TG35 Bianco Tarn cost?
