Recyclable molds

Today I received my first order from Thomarillion. Mainly doors and windows to build my first Inn. Because I recently found a new type of mold material that can be recycled I decided to evaluate it for the reproduction of some of the windows or doors from Thomarillion. Of course its for my personnal use and I will not sell them.

Here are some pictures of the molding material:


It is pretty easy to use. First of all we mix the powder with hot water in order to obtain a viscous paste. This paste becomes hard at low temperature and permits to mold any kind of piece. At higher temperature the solid becomes liquid viscous and can be reused to produce another mold. My preferred way consist in using a jam pot with small pieces of hard material heated for few minutes in a microwave oven. Be careful it's very hot!!!


To prepare the mold I used a wooden box in which I placed the doors and windows from Thomarillion:


Then I poured the hot paste into the box and waited for 30 minutes it became hard in the fridge.

After 30 minutes, the mold is ready and after removing the original pieces we can introduce the Paris plaster into the mold. 30 minutes later we obtain the following pieces. As you can see, the quality strongly depends on the bubbles that appears on surface and is usually much lower than the original.



 In conclusion I recommend this molding technique only for simple pieces with poor details to reproduce.
