Choice of concrete for small crafts

[berne88]

got an idea but I would need your help, I am thinking of casting some items, using a mold or whatever you want to call it, which concrete or something else should I use for the best results.

Since it will be difficult to make the concrete mass itself thick, it needs to be reasonably strong in its construction, but still have a nice surface...

I can't go into detail, but if I succeed, I will definitely post it here.

can self-leveling compound work? if you mix it a bit thicker?

Expanding fine concrete is usually good for casting small items and is almost like self-leveling compound in consistency but more durable. Since it expands a little, it fills the mold better.

mmm have been googling for a while now, and it seems that is what applies.

can use a little less water, to make it a bit stiffer, easier to work with
