Is it difficult to remove from a silicone mold once cured? Thanks!

No... It is very easy to remove from a silicone mold.... It does not stick to it at all.... Just make sure the item is cured....

What's the beast sealant to use to preserve my mold?

I got a clear seal from Lowe's. It works great. Make sure all the paint is dry before you apply it.

Can this be used in alginate mold for 3D hand sculptures? if yes how many double hand molds would 10# make?

This gets very warm when setting up. Do not use for hand sculptures

Can this be usrd on furniture

How do you wanna use it? My go to answer is no it probably shouldn’t be used on furniture. I used it to make molds of clay models.
