Edge Mold

A form for in-situ production of a molded object, comprising:

• a leg portion configured to attach to a substrate;
• a face portion detachably coupled to and extending away from the leg portion;
• and
• a frangible portion coupling the leg portion to the face portion, the frangible portion configured to fracture and detach the face portion from the leg portion.

A method of in-situ producing a molded object, comprising:

• installing a form on a substrate to create a container open on at least one side, the form including a leg portion and a contoured face portion with a frangible section forming a frangible score line connecting the leg portion to the contoured face portion, the frangible section included in the form prior to installing the form;
• inserting a material into the container in contact with the leg portion and the contoured face portion, the material having a flowable state and a solid state;
• allowing the material to cure from the flowable state to the solid state;
• applying a force to the contoured face portion to fracture the form along the frangible score line;
• and
• separating the contoured face portion from the leg portion such that a lower surface of the leg portion is flush with or above a bottom surface of the material.

A form for in-situ production of a molded concrete object, comprising:

• a leg portion configured to attach to a substrate, the leg portion including a front leg surface, a back leg surface, a bottom leg surface, and a leg thickness;
• a face portion detachably coupled to and extending away from the leg portion, the face portion including a side face surface, an upper face surface, a lower face surface, and a face thickness;
• and
• a frangible portion having a frangible thickness less than the leg thickness and the face thickness, the frangible portion coupling the leg portion to the face portion and configured to fracture when the face portion is rotated relative to the leg portion such that the face portion is detached from the leg portion, the frangible portion comprising an indentation from each of the back leg surface and the lower face surface,
• wherein the side face surface is positioned between a plane defined by the front leg surface and a plane defined by the back leg surface and the bottom leg surface is between a plane defined by upper face surface and a plane defined by the lower face surface.
