Always according to what we want thus we must have some or other materials, will obviously not be equal the realization of a lead of fasten (undoubtedly complicated), which one of stem or a pasante. But in all the cases we will require, and in this case the order if it is significant:

• An adequate room, it is supremely significant that it meets conditions of basic safety, lead in its process of liquified emanates supremely toxic gases, those plain with the dirtiness which lead used contains can be the cause of serious poisonings. It must join together, at least, a great ventilation, a source close to water and comfortable conditions for the realization of that melted and the subjection of the moulds, is case to always lack a suitable site between the possibility of carrying out work with the free air with the minimal expenses but without neglecting the basic elements of safety.
   

• Protective gloves, without those all the remainder obvious, we will work with a metal in liquid state which exceeds in its process the 350 degrees. They must sufficiently be forts as to protect us from projections (metal in its process of cooled in the skin can cause large will quemaduras), they are those ideal of turned over leather employed by welders.
   

• A container to melt and pour lead, ground to use one of the stainless steel flasks of which in cafeteria they use to heat, is comfortable, relatively small and heats fast. Even if they have handles I recommend to use one tile for its handling (thus we will avoid surprises in the event of excessive heating or of separation of the latter).
   

• Grip, so much for the subjection of the flask as for the realization of the shapes of the stems. If we miss "cats", of "banks of work" or "sergeants" to hold the moulds, they will be also those necessary called of "pressure" so that podamos to pour the comfortable lead of manner.
   

• A container with water or a close tap. To cool lead, to reduce the temperature which would reach the mould or for an awkward projection it is necessary to lay out, at least of a trough with the invaluable liquid.
