Изготовление формы для декоративного камня из силикона

The material consumption for this form of Alcorsil 340 silicone directly (which is in the video) is 1.9 liters. The volume of this form, or rather the brick itself at the exit: 0.17 sq.m. I don’t use this silicone anymore, I bought it in Ufa at the price of 650 rub. per kg the can weighs: 5 kg and that 3250 p. for the can. The price was current at the time of this video!
