Nyad® A specialty mineral to improve the strength and surface appearance of traditional ceramics, glazes and engobes
- Low loss on ignition (LOI)
- Fewer surface defects
- Improved shrinkage control
- Higher impact strength
- Faster drying times
Due to their unique chemistry, needle-like, acicular structure and low loss on ignition (LOI), our Nyad® wollastonite grades make excellent fluxing agents and frit additives providing a host of benefits in the production of traditional ceramic bodies, glazes and engobes. Nyad® wollastonites are also both cost-effective and non hazardous reinforcing minerals.

Nyad® wollastonite is a unique calcium metasillicate (CaS1O3) which acts as a natural frit and fluxing agent in ceramics bodies, glazes and engobes.
Used as a flux in traditional ceramic green bodies, Nyad® acicular wollastonites are excellent, low LOI replacements for other calcium oxide sources, which:
- reduce firing temperatures and firing cycles, facilitating fast firing and lowering energy consumption and CO2 emissions
- reduce firing shrinkage
- increase green and fired toughness
- improve thermal stability preventing thermal shock
- speed up drying times
Used as a fluxing agent and frit additive in glazes, Nyad® is an excellent low LOI source of calcium which:
- improves surface smoothness and transparency
- improves glaze body fit
- reduces pinholes, crawling, crazing and cracking
- maintains high brightness value during firing
- improves thermal stability
- lowers thermal expansion
- reduces vitrification temperature
- boosts melting of other frit components
Used in engobes, our Nyad® grades
- provide whiteness
- lower opacifier demand
- prevent crawling (drying cracks)
- lower thermal expansion
