An old rubber ball is ideal as a container for breeding alabaster, or rather, one of its halves. Alabaster is much better from its walls than from other dishes, so it will be easier to do all the work. If the ball is not at hand, then you can use a bucket or a small saucepan. True, before using it, put it with the inner surface with polyethylene. This is done in order not to spoil the dishes and not throw it out later. Now proceed to knead alabaster. We fill the alabaster mixture into a container of water per 500 milliliters of water per kilogram of the mixture. Weight is well stirred to the consistency of sour cream. After stirring the mixture, we wait about thirty seconds and start work. Otherwise, the alabaster will quickly grasp and dry, so you have to make a new portion. After the end of work, we wash all the tools from the remnants of the mixture.
