We're B Corp Certified


We're proudly B Corp Certified
As a certified B Corp, we’re part of a global movement of pioneering companies who have committed to use business as a force for good.
Becoming a B Corp in 2022 was a big step forward for us. To be certified, every aspect of the business is analysed and verified to make sure that the business meets the highest standards of environmental and social performance.
We’ve recently completed our three-year reassessment, reaffirming our commitment to these high standards and ensuring we continue to meet the rigorous criteria set by B Lab.
As the first glass art supplier to become B Corp certified, we believe that together we can have a positive impact and make the world a more creative place.

What is a B Corp?
B Corp is a global certification that assesses a business based on its environmental and social performance.
We began the process because we wanted to make a clear commitment to balancing profit with people and the planet. As a company, we already had strong values in place, but gaining our certification pushed us to meet the highest standards of environmental and social impact. Find out more on the B Corp website.
Becoming a B Corp was just the beginning - it’s helped focus our whole team on how we can continue to use business as a force for good. Find out more in our annual Impact Report!


How did we score?
We were pleased to score an awesome 103.9, well above the requirements. The B Corp assessment covers five impact areas, here's how we scored in each one:
- Governance: 17.6
- Workers: 28.1
- Community: 17.2
- Environment: 24.2
- Customers: 16.7
We achieved this as part of Creative Revolution Group, which includes Glass School & Hot Clay. This was scored in 2025, an increase on our 2022 score of 97.3.
We're not Stopping There...
Becoming a B Corp is not the destination, but it sets the standard for our future and the rest of the industry. B Corp businesses need to recertify with an improved score every three years, to ensure standards are met and progress is shown.
