If you are willing to order a sheet of it I might be able to help. I have an account with the UK distro' for Corian (Dupont) as well as Samsung and LG's Product. There are other out there including Krion out of Spain (made in South Korea to my knowldege). HI-MACS and Corian tend to be the most commonly used of solid surfaces for Lithophanes. Solid Surface are NOT even 50% acrylic, though acrylic is one of the major items in them. catch me on skype.
