Very nice!
I am curious about the elasticity of the mould material that you used given the amount of mould stretch necessary to clear the headstones on top of the piers when you pull the casting. Any idea how many pours you might get out of the mould before it tears in that area?

I had the same question. I wonder would it be better to make a separate mold for the headstones and glue both castings together...
Nice job.

The rubber used was alumilite quick set. Nothing quick about it 8 to 18 cure time. It is a 1 to1 ratio by vlm or wt. The resin used was amazing casting resin demold 5 min. As far as I can tell the is a LOT of stretch to the rubber. As far as hiw many pours b4 it tares I dont really know but there is pleanty of stretch. I am waiting on the store to order me some more rubber but I will be doing a tutorial on mold making soon. Hope this answers your questions.
Thanks for the feedback. I'm really looking forward to your tutorial!
Nice first try!

What brand of mold making rubber did you use?
