Borax also has powder and granular points, fine-grained borax is the best. Borax is divided into two grades according to strength. 10 Moles of Borax has 10 water molecules, called 10 levels of borax water. 

5 Moles of Borax have 5 water molecules, called Class 5 water borax. 5 Mole borax concentration is higher. 0.35 kg of 5 mole borax is equivalent to 0.454 kg of 10 mole borax. When the same amount of Borax is used incorrectly, the consequences can be severe. If borax is added to raw starch and water emulsions and the mixture is heated, the starch absorbs water and expands rapidly, becoming more viscous than if borax was not added. The addition of Borax to a certain extent, otherwise, it will affect the expansion of starch, gelatinized paste and become brittle, dry when the powder state. Caustic soda is available in granular or flaky form as long as it contains 76% sodium oxide and is commercial grade without additives. It’s 98% sodium hydroxide. Caustic soda absorbs moisture from the Air and reduces its strength. Therefore, the packaging drum if there is damage, not suitable for use. The Lid of the barrel should be tightened immediately after the material is taken from it.
