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.
