Sample Evaluation Before You Commit to a Container
Nobody should qualify a new flux on a supplier's data sheet. We ship 1-5 kg of each grade you want to evaluate by DHL or FedEx at our expense, with a Certificate of Analysis in the box so you can compare your numbers against ours.
How It Works
Tell us what to send
Name the grades, your application and the destination address. Samples are 1-5 kg per grade, at zero cost and zero obligation.
Courier, 5-7 days
Samples move by DHL or FedEx and reach most international destinations within 5-7 days. Each one includes its COA.
Fire a test disc
Press and fire discs at 1200 degrees C and measure whiteness in L*a*b*. This is the same test we run in-house, so the numbers are comparable.
Build a trial body
Replace your current feldspar in a trial formulation, fire test tiles, and measure water absorption, shrinkage and strength.
Compare three ways
Against your current raw material, against our COA, and against your own retained reference. Most buyers finish the evaluation in one to two weeks.
