Mold making for tile work

26 Apr

When I make a tile, I also make a mold of the original so I can make multiples.  I thought I would share with you a little bit about how I produce a plaster mold. First, I construct the original tile.

After the original tile is constructed, I placed it inside a wooden plaster mold form.

This form was built so it could be adjusted to make various sizes of molds depending on the size of your original. (One note, you can see the bird’s profile is the opposite direction in each photo.  I made two original tiles and molds of the bird in left and right profile, but forgot to take a picture of each profile.  Sorry if I have confused you.)  After the joints are sealed with clay so there is no leakage, plaster is poured into the form over tile and left to set until hardened.

Below is the finished mold after the clay form and clay was removed from the plaster mold.  The original tile will most likely not be able to be used, but I have the plaster mold to make more.  It is now ready to press clay into the negative spaces.

    Can you slip pour the tiles rather than press? Or is there too much absorption

      It should be just fine. Slip molds are made of plaster as well. Using slip is something I am interested in and is on my “next project” list.
