Whats the investment?

After some browsing on the TDM forum, I saw that a jeweller used 36 parts water to 100 parts investment (Plasticast). I decided to give this a try as well as use the existing investment powder used for normal wax castings.

The results are as follows : (Normal Investment Powder)


 
(Plasticast Investment 36:100)
 

 
The normal jewellery investment powder cast very similarly to the Plasticast Investment powder which means that the investment powder might be the problem.
