Making the model for the mold: November 2014:

 

The basic outline is made using Styrofoam which will then be covered with clay for detail mock up.  Styrofoam is used to minimize the cost of the amount of clay required.

Foundry Workup:

 

 

The final bronze statue will be made at Genesis Bronze which is located in Paso Robles on Dry Creek Road near the Warbirds Museum.  Their artists/craftsmen will convert the clay sculpture that Mark made to the final product.

 

And lets follow their progress:

 

 

Their website: http://www.genesisbronze.com

 

 

 

The fence post with the lizard on it is ret angular and has been parted onto 2 halves...the top half with the lizard is above the parting plane (the brown edging with the holes in it) supported by 4 sections of clay (the blue supports) ...with the lower half out of view inside the blue supports.

 

The fence rail to the left is likewise parted at the center, half above the parting plane and half below.

 

Rubber will be applied to assume the shape of the sculpture and then covered with fiberglass and let harden. This will enable the bronze to be poured and form half the post/rail.  The other half will then be done in a similar fashion and ultimately the 2 halves will be welded and polished for the finished post/rail.

 

 

 

Scroll down to the Foundry Process section for more details on the actual process.

 

 

The arm and head need to be removed for separate handling of the rubber/fiberglass/wax/ceramic process due to their unique shape:

Alan and Mark working the wire to sever the head Chuck still has a smile, as does Mark

 

The rest of the body will be parted using metal shims to mark the "center line".  After the shims are finished each half will be covered with a rubber coating.

April 24, 2015

 

The face has been covered with the Gypsum/Fiberlass coating and the shims (cards) separated the coating into 2 sections.  After drying, these sections were taken apart and the clay sculpture removed. The plaster sections are lined up and held in place with some bolts on the shim line.  This leaves the rubber representing the sculpture hollow inside, and supported by the Gypsum..

 

Hot wax is slowly poured into the opening at the base of the head, rotated gently until it coats the rubber.  Several coats of wax are applied to the desired thickness.

All rubber coats on the head, plaster is beginning to be applied    

 

 

 

 

After the wax has been poured and hardened, the Gypsum is taken off the rubber Then Dottie removes the rubber from the wax.  The dark brown face is the wax

 

 

This shot shows the wax face, which is hollow, compared to rubber coating which had picked up features of Mark's clay sculpture.. note the detail evident on the rubber which was picked up by the wax.

 

The next step will be to coat the inside and outside of the wax face with a ceramic coating. More to come on this process later.

 

The ceramic and wax will be placed in an oven and the wax melted out...leaving a gap where the wax was.  This gap will then be filled with liquid bronze to form the head. When cooled the ceramic will be chipped off the bronze and discarded. The bronze will be the thickness of the wax mold.  Later steps will include welding the bronze head to the bronze body (yet to come) and a lot of fine detail hand finishing.

 

 

The arm has been formed in a similar fashion.  This view shows the wax arm resting on the rubber mold supported by the Gypsum.  Note the watch imprint on the rubber.

Body is laid horizontal, Alan removing Gypsum from top/back of the clay statue Gypsum/Fiberglass support removed.  Rubber coating still attached to the clay statue

 

 

Rubber is removed from the clay statue Rubber is refitted into the Gypsum support.  This is the back half of the statue top.  Note the light colored nodules around the rim. This shows the still installed front half of the upper body. The separation was at the shim line and the obvious depressions will later be mated with the nodules on the back half to retain alignment of the halves when they are mated

June 1, 2015: Waxing the legs

 

Gypsum leg halves have been attached Alan taking wax from the vat - wax was heated by the hot-air blower shown pointing at the vat Top part of Gypsum mold with hand application of wax
Hot wax being poured inside the Gypsum mold Mold is rotated to distribute the wax Inside after 2 applications of wax.  First application is the most important as it picks up the features of the inside of the Gypsum mold.  Subsequent applications are to get a suitable thickness of wax (and final thickness of Bronze)

 

June 8, 2015

 

This is a wax of the front chest with Cosmo showing the rectangular connectors..these are also wax and attached to the chest with hot wax.  All will be dipped in the ceramic coat (coming photos) to provide a path for the liquid bronze to flow to the main feature (the chest in this case).

Completed wax molds with the attach structures for liquid bronze flow.

  Front chest, head, and left arm.

Dusty applying a pre-coat of silicia compound to make sure the critical features are sufficiently covered.  The first coat is key to pick up all the details from the wax.

 

 

The pre-coated head is to be dipped into the vat of "Primecoat", which is a silicia compound which makes a "ceramic" coat when sand it spread on it (to come....) The head and the feeder lines are completly dipped

 

 

Sand is poured on the outside and inside of the head...the sand adhering to the "Primecote" silicia compound The first application of the "ceramic" is completed...Dusty is pleased as all of the wax features have been replicated.  This is allowed to dry for about 1/2 hour prior to the next coat. This is after the second coat.  A total of ~12 coats will be applied to get the proper thickness of ceramic.  THEN the wax will be melted (from the head and the feeder lines) and the remaining ceramic mold (remember it will be the thickness of the wax) will be filled with the hot liquid bronze.

 

June 11, 2015

 

The statue parts are all being ceramic coated.  These parts have 9 coats with several more to be applied.  The next step will be pouring the liquid bronze.

 

 

   June 18, 2015  Pouring of the Bronze

Foundry Process - In Words

 

The obvious first step was to have Mark create the clay sculpture, the "rest of the story" is sort of like this:

 

The foundry will cut off the arm and make a separate mold. Then separate the rest of the sculpture into segments using shims . Each segment (or panel) will be around 16 x 20 inches and there will be about 12 of them.

Once panels are shimmed they will apply a fast setting rubber that when dried retains the shape and detail of the original sculpture.  After 5 layers of rubber a layer of Gypsum with fiberglass is applied and left to dry to support the rubber mold.


When the production mold is pulled apart the original clay copy is removed and the rubber surface (supported by the Gypsum/Fiberglass coating) is lined with wax to a desired thickness.  When the wax cools the wax copy is pulled from mold (the fiberglass and rubber is removed). The wax copy then has feeder wax tubes welded (hot wax weld) to the wax sculpture piece.

The piece is now ready to be dipped into a 50 gallon vat of a liquid ceramic mixture. This mixture when dried will pick up all the details of the wax copy.

They will layer the dipped copy with silica sand to about 3/16" thick. When the ceramic is dried the entire structure goes into a 1000 degree furnace that will melt all the wax (the "lost wax" process).

Now you have a shape inside the ceramic cavity that is exactly the shape and detail of the original clay sculpture.  Bronze is heated to 2000 degrees and the molten metal is poured into the mouth of the ceramic receptacle.

When the bronze cools the ceramic is broken off and the piece is now bronze with a thickness of the wax. The foundry takes all the bronze cast pieces and welds the sculpture back together. All the welded seam lines are resurfaced (by hand) to look like the original.

The next steps are sandblasting the entire piece, then heating, and applying chemicals to the surface of the bronze to patina (color) it. The last step is to wax it.


The statue will be mounted to the concrete patio using ¾” bolts through the feet and one 4x4 post.  The bolts will be epoxied into the cement surface.
