Place of Origin:
Strontium carbonate powder CAS NO 1633-05-2 was used in making special glass and ceramic glazes
carbonate salt of strontium that has the appearance of a white or grey powder. It
occurs in nature as the mineral strontianite.

Refractive index (nD)
Strontium carbonate is often recommended as a substitute for barium to
produce matte glazes. Use about 75% as much and test first to make sure color
response is the same. However strontium is not a substitute for barium as a
precipitator of soluble salts in clay bodies because it combines with SO4-- ions in
the water to form a compound that is not nearly as insoluble as BaSO4.Viscous
zirconium silicate glazes can be smoothed with the addition of strontium carbonate.
Strontium is considered a safe material. Some people confuse SrO with
Strontium 90, an isotope released from atomic reactions; they are not the same
As noted, strontium carbonate produces gases as it decomposes and these
can cause pinholes or blisters in glazes (if they are being generated into a glaze
melt having a viscosity and surface tension that is unable to pass them or heal over
properly as they escape or one that simply does not have time because of quick
cooling). There are many strontium frits available and incorporating one of them to
source the SrO instead of raw strontium carbonate (a classic job for glaze
chemistry calculations). The resultant glaze will be more fusible and will have better
clarity and fewer defects. Strontium frits have become much more common of late
and are useful to producing brilliant transparent glazes without having a high
expansion (like those based on Na2O and K2O). Please read the information about
the oxide SrO to fully appreciate the value of SrO frits, not just as alternatives to
this material, but as excellent ways to produce brilliant glazes.
