I have created many mouldings using bonding plaster for walls, in UK it is called bonding, and after setting it you can bake it in the oven for 4 hours at 150 degrees and they became solid as rock, I used them for replacing some missing decorative brackets or supports under a window sill, though they were for decorative purpose as the sills did not require physical support to the overhang.
its plaster of paris you get it from any builders merchant who deals with the plastering industry but one note its not easy to work with cause it goes off very quickly
Just out of interest, how come you guys don't simply create a relief mold, and lay up the plaster so that each cast comes out with the smooth front surface already made each time? Rather than needing to create the front surface?
I thought that. But he I believe renovating some protected British Heritage buildings require any replacements to be made as the original installation. In this case maybe the original cornice was run in situ using slaked lime putty and plaster. Running it on the bench and using hessian canvas to strengthen it may have been an easier and acceptable alternative.
Camilo Loyola tap the mould with a hammer to ring the bubbles to the top..... this is a very lenghty process that can be shortened by about 80% on this vid

How we do it in USA you get straight lime mix it over night put water on it then get plaster moulding make a ring with the lime pour water in it put moulding in it more moulding the faster the set up time usually a 1 to 1 with moulding
