Thx gents for all your comments and likes.
@Thomas Marocke it is depending on the type of resin you use. Yes the reaction of the chemicals create heat but the amount of heat is depending on the speed of the proces and the amount of resin. The quicker the resin is curing the more heat is created. In this case I used a quicker curing resin for the bottom part, curing in max 48 hrs and with this resin you can pour up to 3 cm max. The second pour I did with very slow resin which you can pour up to 10 cm and cures in 7 days.
Last factor is the room temperature which is perfect around 20-25 deg. Higher and the process speeds up with more heat as a result too cold and the process will never finish and the resin never cures.
As I had some crystals in the resin due to lower temperatures when stored so I had to heat up the resin in a bucket of warm water. Due to this I had more heat in the process then I anticipated resulting in some air bubbles around my anchor and some heat shrink at the corners of the mould.
But I like the result as of the anchor is just dropped over board.
I use tape for easy removal from the mould. I dont use release spray as these often contain grease or teflon which I am afraid can ruin the resin while getting into it during the pouring.
I will plane, sand and polish the outside surface after removal from the mould, but that will take another week.
