What is the model made of? Models all over the world are made of wood, wax or FRP. Wooden models were made in earlier years where they had to be hand finished to get the exact shape of the ship and it used to take a long time, but with increasing or rather depleted wood sources and the skill for manufacturing models in wood reducing, we have switched over to wax models, which we do in our hydro dynamics laboratory here- wax models over a wooden, wood and bamboo frame work is called a composite model made of wood and wax. Or one can make an FRP model- so, there you make a wax plug, a female mold and then the male model. The advantage of making a FRP model is, which is thin, but it is strong and it can be preserved- wooden model can also be preserved, but wax models cannot be preserved, so wherever you do not require preservation of the model you can go for a wax model and the model can be destroyed afterwards.
