I am sorry to hear that. There are many of these type of estate pipes in Ebay, I believe some of the sellers do not even know the differences between meerschaum, gypsum or asbestos. so it is best to be more cautious when buying online and from unknown sources.
A while back, in another forum, there was a discussion with Deniz Ural on this issue which may be useful for you.
"….The lining of the bowl of the South African Calabash is "quick-setting gypsum (calcium sulphate semihydrate) plaster....." "which hardens when moistened and allowed to dry". (Exact description from the encyclopedia.) Called Plaster of Paris because gypsum was used early near Paris, France to make plaster. It's been used since ancient times to make pottery vessels, to pre-cast and hold an ornamental cornices for sculptures and medical plaster casts amongst other things.It's easy to work with, sets quickly, has a neutral taste and will accept the temperature of burning tobacco - which makes it ideal for lining the calabash pipe, especially since we don't have any meerschaum in South Africa. We often describes it as "clay lining" because the smoking sensation is similar to that of clay smoking pipes.It is difficult to describe the difference between meerschaum and clay. They both neutral taste and can withstand the heat of burning tobacco. I think that the essential difference lies in the fact that the meerschaum is more porous and will hold the residue of the moisture from the tobacco (which gives it its colour) - not to mention the beauty and lightness. There is NO better material other than the High Grade Turkish Meerschaum to be used as a bowl/cup in the Gourd Calabash pipe. This piece of information makes me ;a) wonder about the Calabash pipes made in Africa and b) reminds me of some carvers and their use of plaster of aris/gypsum sometimes seen on the internet......
