Just one question

Hello I am kind of new to the forum and was wondering what kind of clay is BEST for sculpting. Can anyone help me?

The most people work with Super Sculpey, as I did some time ago.

Yes, Super Sculpey is used by many, but they also say it is a bit too soft ( I am a total newby in this, but I find it very soft, too.
As far as understand, here is a kind that is hard, which is too hard, but a mix is fine.
Lately a medium-hard Sculpey has been launched, but I can't remember what it is called

THANK YOU!

You are wellcome.

I am sure there is an ansver to all questions, - the job is to find it

A lot of model horse people use an epoxy, such as Magic Sculpt, or Aves Apoxie sculpt. Super Sculpey is very popular too, and is sold in soft, medium, and hard. It's all personal preference. I am a big fan of Magic Sculpt but I don't sculpt models from scratch, I just use it for model horse customizing.

What little sculpting I've done, I've used original Sculpey for. It does seem as if it would be easier if the clay were a bit stiffer, but it worked. It's a bake-to-fix material.

Another website I'm on recommends the Aves Apoxie Sculpt. A high end figurine company whose work I collect recommends using the Apoxie Sculpt for repairs on its figures. It's a two-part epoxy, air hardens. It's very soft at first but stiffens over an hour or so.

I have recently begun using Kato Polyclay. It is an oven-bakeable polymer clay, similar to the Sculpey products. It is about as firm as Super Sculpey Firm. I like the way it responds to my hands and tools better; it's less "crumby" than SS. It's also a bit less expensive, at least at Hobby Lobby.

I also really like Monster Clay. It's an oil-based modeling clay. Unfortunately, the only way to make a permanent piece from Monster Clay is to mold and cast it - a daunting process for most hobbyists! But if you want a material to use for non-permanent clay "sketching", you can't beat it. One of its best characteristics is its heat sensitivity; it's very soft when warm (in fact, you can melt and pour it like chocolate) and gets firmer as it cools. At room temperature it is comparable in firmness to Super Sculpey. If you want it firmer than that, just chill it in the refrigerator or freezer.
