Junior Geo Small Ammonite Fossil silicone mould for making plaster casts

This mould is not a professional retail-quality mould. It looks home-made, the silicone looks contaminated and has not been degassed (it has more bubbles than an aero), and is a physically different ammonite to the picture with very little detail coming through in the finished casting. Definitely not worth 10,95

Really great. You're probably not supposed to, but we used it as a mould to make chocolate fossils. :-)

I have used this mould with artists' texture paste and it has come out cleanly without any release agent being needed. The texture paste is a mix of PVA glue, white acrylic paint, bicarb and talcum powder.

perfect ... will now buy the larger size!

Great quality and lovely image.

Great product. Works well with plaster

Started collecting these ready for next term's topic. Very good value.

Great product easy to use
