Apologies to Mahmoud Zaefi who asked a question on our last upload, we had to re-edit the video and upload it again. If you find this new video the answer to your question is...... silicone moulds will last longer than latex. latex tends to decay naturally after a while just like how rubber bands start to disintegrate . silicone will last a lot longer and resist resin casts better
as long as you are careful how much you put in it will be fine . we recommend adding between 1 and 10% thickener to latex. if you were doing small moulds like chess pieces i would just dip or paint on more layers of unthicken latex. avoid brands of powder based thickeners as they are more likely to weaken the mould.

Many thanks, Very Useful.
Would you say the mould is not compromised with the Thickened Latex ? I was unsure whether to use the Thickener.

Hi could I ask is natural latex or prevulcanised better for casting?
Hi Unfortunately we are not familiar with the prevulcanised we have never compared them.
