To Whom It May Concern:

February 20, 2015

Mika Eronen has been a valued colleague of mine for some time. Not only does Mika possess an

extraordinary understanding of glass, and its material make up, he understands the process needed to

produce a quality product.

When writing my book, I consulted Mika to verify my theories and testing. He is a well-respected expert

in his filed both in the Europe and the United States.

Mika’s real value is found in his passion for glass and his timely fashion attacking a challenge.

Sincerely,
