Casting Molds With Voids
Yeah! That would be great... casting it directly on a wall (or something). The unmodling could be done naturally with time and passers-by.
would be neat if you could cast it in place with colour pigment (so it will always stay the same colour), then you wouldn't need a lock and people would wonder how it ever got there. Obviously this would involve it not getting disturbed while curing and having to go back to un-mold it
That is so cool. I am tempted to make it and place it on some trees on our land where it is visible from our windows. If it is poured from concrete, it would be a good idea to place some sort of metal or plastic mesh within the mold that will help to give strength to the solid piece. This sort of acts like a backbone and can prevent cracking if the item receives a hit or dropped while handling. Chicken wire with 3/4" mesh or some stiff wires or metal rods like metal hanger pieces would work. I am also thinking of bypassing the solid concrete aspect and keeping it light by using only the sculpted heart which gets covered in fiberglass window screen that you attach to the foam form. Using some sort of cement like mastic (stucco) can cover the exterior and be paintable. This is a technique that I see on store fronts when new stores are built.Thanks for getting me thinking.
Looks good and it will last a lifetime.
