Glass-to-Glass Graded Seals

Moores Glassworks are a world leader in the manufacturing of graded seals. With forty years experience in the industry, Moores Glassworks know the most reliable methods of creating glass-to-glass seals. By using our unique tried and tested methods, we create a graded seal to join the glasses. A graded seal is used when to materials have different coefficients of thermal expansion. In this case we use a series of intermediate sealing glasses between the two different glasses. The linear coefficient of expansion must be close to avoid these seals from cracking.
