A process for fabricating cordierite-type magnesium aluminum silicate regenerator cores comprising the steps of preparing a glass powder and combining it with a block polymer binder, forming the binder and glass-ceramic mixture into a ribbed tape which is wound upon itself to produce a honeycomb structure and subjecting the honeycomb structure to firing cycles to achieve binder burn-off, controlled nucleation, densification and crystallization whereby the glass-ceramic structure is characterized by a relatively low thermal expansion during operation in an environment where temperature reversals occur, the glass ceramic structure thereby being more resistant to chemical attack due to corrosive gases in an engine exhaust gas environment and the strength of the structure thereby being increased.
