Re: Liquitex Cadmium-Free question:
Hi jaytref, and thank you for your question!
We checked with Liquitex to see what their plans were, and they confirmed that for the time being, the Cadmium Free colors are only available in their Heavy Body line, although it's possible they might consider adding them to other ranges in the future.
They suggested their Gloss Medium and Varnish or Matte Medium as useful additions to make the available Heavy Body colors more fluid. Thank you for your interest!
