Hi! Thank you for this post :)

I also do cosplay and I start to use resin but I face a difficulty, could you help me?

I made a mold using this (40mm diameter half-sphere):
It's a silicone gum, the saleswoman confirmed to me that it is indeed material to make resin mouldings.

In the end, my resin has a kind of whitish shadow at the lowest point. Do you know what could have caused this?
We see it vaguely on these photos, it is difficult to take a picture because of the reflections but in reality it is obvious.

Do you think it's dust ? Did I miss mixing the two phases?

Thanks for your answer :)

It is most likely the dust that settled in the mold.

Thank you for your answer. I'll try to do them again with more caution.

Do in any protective casing, so that dust does not get from the air.

I did it with the means, but in the concept it should work ^^. Thanks again!
