Hello, I purchased the 1/2 gallon jugs of Artwork Resin last summer. The Hardener has turned brown. Can I still use it and will it still be crystal clear? Why did it turn brown?
Thank you

Hi Lynn,

I’m afraid all resins will yellow with time. It sounds like you’ve stored it well, so it should cure without any problems. It’s best used for your projects that you’re coloring.
