We have commissioned a brand new analytical instrument, a Handheld XRF Niton XL3T. This is now being used to analyze our incoming raw material in situ. It is allowing us to take more frequent and faster measurements, identifying chemical variations and resulting in a more consistent final product which is essential for all our customers.


Celebrating 50 Years


Calumite was first developed as a raw material for glass making in the US in 1944 by RW Hopkins, founder of the Calumite Company.

Calumite Ltd was established in Scunthorpe in 1969 as a joint venture between the Appleby Group and Calumite International to introduce the material to UK glass producers.
