Pakistan processors are processing soapstones that come
from mines in Pakistan.
Pakistan soapstone consist of following
minerals (as per Chemical & Environmental Laboratory Test
Report dated 06 February 2015, testing conducted by SGS
Pakistan office.
AROUND %
i) SILICA (SiO2) 60.23
ii) Magnesium Oxide (MgO) 31.13
iii) Other minerals (Calcium
Oxide (CaO), Iron (Fe2O3), Alumina
(Al2O3), Chloride(Cl)-(Water Soluble)
Loss on Ignition (LOI) @ 1050-C 04.68
Whiteness Ry 99.04
Brightness R457 95.39
NOTE:
1. Talc is a hydrous magnesium silicate mineral with a chemical
composition of Mg3Si4O10(OH)
2. Although the composition of talc usually stays close to this generalized formula, some
substitution occurs.
2. Small amounts of Al or Ti can substitute for Si; small amounts of Fe, Mn and Al can substitute for Mg; and, very small amounts of Ca can substitute for Mg. When large amounts of Fe substitute for Mg, mineral is known as minnesotaite. When large amounts
of Al substitute for Mg the mineral is known as pyrophyllite
3. Pakistan and Afghanistan soapstone contains more MgO & SiO2 but with a certain ratio, therefore this quality is considered better.
4. Pakistani/Afghani origins Talc contain MgO percentage between 29% to 31% , SiO2: 59% â?? 61% and LOI: 5% â?? 6%.
5. The offered stone is the best quality extracted from the mines in Afghanistan and in Pakistan.
6. Soapstone or Talc stone is graded with whiteness which should be over 95% whiteness to fall under â??Aâ?? category.

Soapstone is a soft, metamorphic rock composed primarily of talc, chlorite, pyroxenes, and other minerals. It has a smooth texture and is easy to carve, which has made it popular for sculpture and craftsmanship. Soapstone is used in various industries like Ceramic, Medicine, Talc powder, Soaps Etc. Its colors range from pale gray and green to blue, brown, or black.
Soap stone with thermal qualities used in pizza ovens, kitchen counter tops & flooring tiles etc.,
Packed in standard wooden crates or as per the requirement of the buyer.Usually packed in quantities of 240 sq mtrs. We can supply slabs of 2feet to 4 feet in width & free length of up to 11 feet
