The Spectra Group Companies developed Spectra-Glaze® block over 50 years ago and set the international standard for glazed finishes integrally bonded to concrete when it developed and refined Spectra-Glaze® block in North America and Europe. The Spectra Group traces its origins back to 1788 when Alexander Russell I formed Burns, the Berry and Russell Brick Partnership. Today, the business is still operated by Russell family descendants.
Evolution of Spectra-Glaze® block
In the early 1950’s, the Russell family expanded operations to include coatings, basic chemical research, additives, minerals, pigments, ceramic coatings for metal, and new polymer compounds. With the unique discovery of how to combine organic and inorganic molecules
to form new substances, with superior properties,
Spectra-Glaze® glazed concrete block was born. The Group’s glazed block introduced a new, innovative, colorful, high performance and cost-saving pre-finished concrete block that has been used to construct all types of structures throughout the USA, Canada and overseas.
The Spectra Group consists of affiliate technology operations that license the production of Spectra-Glaze® block, produce polymers, minerals, pigments, chemical additives, fire retardants and manufacturing equipment. The Group also conducts ongoing testing, establishes quality standards world wide and conducts applied research which has resulted in major innovations in wall design, corner systems, colors, light stability, weathering, stain resistance and the properties which exceed the ASTM C-744 standard for glazed surfaces for resistance to fire and flame.
During our long history, of developing and producing masonry products, dating back to 1788, we provided hand made and machine made bricks to famous structures throughout Maryland and across the country, including the Johns Hopkins Hospital, Marshall Field House in Chicago, the Peale Museum, the B&O Railroad bridges, poet Edgar Allan Poe’s Historic home, the Baltimore Shot Tower and the Vanderbilt homes in New York. These historic uses remain today as landmarks to the group’s fine products, heritage, and quality.
At the Spectra Group and the Russell family companies, the group develops technology that is transformed through scientific research into innovative manufacturing systems, to produce raw material and finished products. The process of innovation has resulted in continuous improvement of Spectra-Glaze® block, and the development of the glazed block industry.
The Spectra Group and the Spectra-Glaze® Product Information Center is the coordinator for new plants, product information and licensing administration on a national and international basis.
