Process & Quality
Escol Products Limited ~ Process and Quality Information
The sole manufacturer of vitreous enamel frits and electrostatic powders for steel and cast iron in the UK with its products sold worldwide. The company is a member of the Stewart & Gray Group, established 1919.
The smelting of Escol frits is carried out in specially designed kilns where temperatures can be in excess of 1200°C.
In order to achieve homogeneity and consistent results, all frits are smelted to a specific cycle, water quenched and then dried in special rotating drums.
As well as the manufacturing facilities, the Huntingdon site has specialist laboratories for Quality Control, Research and Development, Powder Development and Colour Matching (including the use of a spectrophotometer for accurate colour control).
All frit bags provide full identification for record purposes which enables retracing technical information after the consignment has been despatched. Samples of each batch are kept for 6 months as part of a complete technical backup service for customers.
At Escol all frits and enamel powders are fully tested and approved to rigid standards by a team of experienced chemists to meet customer-specific use.
A continuing research and development programme seeks to both improve existing products and develop new frits to meet the demands of the industry. Special attention is paid to individual customer requirements in solving their enamelling and related problems. Full technical reports can be prepared and submitted incorporating such areas as cross-sectional views through vitreous enamelled steel or cast iron products for microscopic evaluation.
