A letter from our Founder. Our job is to help you understand. Your job is to change the world. Nick Ehrmann, Founder and CEO, Blue Engine. Glass Frog has been a port in the storm. What our clients are saying.

While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent. The internal viscera, including the heart, liver, and gastrointestinal tract are visible through this translucent skin, hence the common name.

Information on collecting swedish glass, date codes and signatures for Orrefors and Kosta Boda. My husband and I have been collecting Swedish glass for many years now. We are fascinated by the variety in design and techniques that were invented by the Swedish glassmakers and which revolutionized glassmaking in the 20th Century. However, throughout the years, we have found that the information available on this subject is very limited and difficult to find.

Trust in the Lord with all thine heart; and lean not unto thine own understanding.
