I recently received a garden ornament catalog from a very classy outfit in the UK called Haddonstone. Very nice. They refer to one of their material processes as "dry cast limestone". Seems to be a high-end cementicious material that doesn't have to be sealed and allows lichen growth and natural patina effects to take place. They use it to economically duplicate real limestone, and utilize it for garden sculpture as well as fountain components. I have use for such a material on a couple of things I am working on, and have been having very little luck getting any help from people in the industry. They all view their mixes as proprietary, and that is ok. I am somewhat familiar with "cast stone" and the use of different aggregates in portland, but this stuff sounds different. Is anyone familiar with this? Jim Tallman
