“I work for Boston Scientific Corp; our business is in medical devices where quality is the key to the success of our business. We know to expect quality and reliability 100% of the time from Derek Day.


As a customer of Derek for the past 9 years, I can attest to the quality of the service he provides. Time and again, Derek has fabricated complex bespoke glassware to our designs and tight specifications, the results never fail to impress me.


Customer service is extremely important to me, and Derek provides this in bucket loads. Demonstrated through the personal attention you receive when you arrive with a problem, the collaborative approach to finding a solution, and the timely turnaround of orders. Derek is a craftsman that can create a new piece from a rough outline and provide a functioning prototype in a matter of hours; he will then work with you to provide a tailored solution to your business needs.

I cannot recommend Eirglass highly enough.”


-Ray McCarthy, Senior R&D Engineer, Boston Scientific, Galway.

”FOSS has worked closely with Derek for more than thirty years. He has been an invaluable technical support for development and production of highly complex glass item in all those years. Now Derek Day has started on his own and FOSS is pleased to have the opportunity to still be able to draw on Derek’s expertise in complex developments. His flexibility, know-how and affordable prices makes him a good alternative for us to our low volume items” –
