Important Question: Casting Plaster

[NSStudios]

I have some 74-30 rubber molds and I was wondering if I could cast plaster in them to make master copies of the pieces? Is this a possibility or could it damage the molds? Keep in mind I have Mold release. A quick reply would help me tons! Thank you!
