Primary product Feldspar

Choose the feldspar type based on process behavior

Potassium and sodium feldspar are not interchangeable in every ceramic or glass process.

  • Define whether melt behavior or body strength is the priority.
  • Share production constraints where flux response matters.
  • Confirm target chemistry profile before asking for price.

Ask for chemistry and form together

Chemistry without particle form creates trial uncertainty.

  • Confirm potassium/sodium content expectation.
  • Select form and mesh according to process feed system.
  • Request typical impurity limits relevant to end use.

Reduce import risk with a trial-first structure

A clean trial plan makes repeat ordering faster and safer.

  • Start with controlled trial volume and fixed grade.
  • Use same packing basis intended for repeat orders.
  • Pre-align documents and dispatch timeline for quick scale-up.
