COP 03 / Practical / Jesmonite experiment 02

Following the previous attempt, I started again. The first step being molding clay (the best part). This time I avoided a large grotesque shape, and tried to formulate a more abstract and attractive style, which still communicates the idea of 'natural' rock. Although rocks are imperfect, I noticed how difficult it was to ensure it looked natural, and not too over done. This was achieved by not being so precious about where I was mark making, and cutting away loosely at parts of the model.


Using the different objects to create texture was the most effective, combining them to layer different textures together e.g crystal and bark.



To achieve a more focal area around the logo, but aiming to remain authentic, I roughly cut away on the rock with tools to create a flat area and proceeded to emboss my logo onto the clay using the laser cut. 

As can be seen here, the mold looked much smaller than the last prototype which is what I was aiming for.

This time there was a protective lid placed over the nozzle. The cardboard was set up cto create the cast, exactly the same as previously. Vinamold was then poured into the cylinder. 

   

This time there was a lot of initial bubbling on the vinamold which is never really a good sign. 

The following day the mold was opened to reveal the cast. Unfortunately to make matters more difficult, the nozzle had melted under the heat of the melted vinamold. This meant that the cast of the product had more room around the nozzle which would likely mean when the mixture would be poured in to cast the shape, it would seal the bottle and render it unusable. To avoid the jesmonite doing this, clay was added around the sides of the bottle, to attempt to preserve the function of it. 




Jesmonite was poured in and left for 30 minutes. Upon taking the cast out, the clay had distorted the intended shape, and was embedded within the structure. To clean it up, using tools the clay was chipped and picked away. However, the shape of this bottle looked as though the bottle was erupting from the form, and still actually appeared to have a dynamic look to it. 

This will now be further cleaned up and tested.
