Hello ,

I have a box of 10x translucent pigments, easycomposites, will they still work with the glasscast 3/10/50?
I bought some glasscast a few years ago and do get air bubbles sometimes, I do small projects and only have a basic set up, can you tell me which if any of the clear epoxies 3/10/50 is more or less susceptible to air retention?
I get good results mostly butt its been a while since I last bought and curious to know things have changed.
Thanks for your time, Liam.

The translucent tints are compatible with the entire GlassCast range of resins (and many other resins too). 

In terms of the resin formulations have not changed.  All 3 resins still contain degassing additives to help with bubble removal which they do very well.  However you can help this along by mixing more carefully to reduce air entrapment and also working at 20C as a minimum.  The colder it is the thicker the resin gets and more air gets trapped.
