Due to the fact that I am working on another project, I had to order a "2 component foam-stuff" and tried to cast some
light-weight bricks

First of all, that foam-stuff is tricky to handle :facepalm :lol

First time, misscalculated the material, so I've casted only about half of the brick. Second try, was a little too much of the stuff. In addition
the preasure extended as well (that foam stuff is tricky ). Under the preasure of the foam the "innerside" part of the mold, moved too far to one side. The "thickness" of one side of the final brick is not thick enough. So i fixed the the mold parts. Last and third cast turned out quit nice.

Enclose some pics. Details are a little less than the casts with "Acrylic one" (mineral powder and a water based acrylic resin) but so far I am pretty happy how the turned out

Here are some pics:

Left to right... 1 to 3rd cast (middle/2nd casts back already cleaned up a little)


the bricck in front is the second cast

As next I will try to paint the last cast, to see how that works.

Thanks for watching/reading
