Alganyl
I mixed up a quick batch of Alganyl following the recipe found here after coming across a paper on it. I was curious to see how well it was able to be cast and formed. It cast really nicely especially when the mould is heated so that it does not set before filling the mould. Of course, because it has such a large water content it shkrinks considerably.
