Foundations and basic Techniques of Laboratory

Objectives of the Experimental Alchemy

The fundamental objective of the experimental alchemy is imitate to the nature in their processes of transformation of the matter with the purpose of achieving their improvement. It is to complete to perfection with that biblical command that it pray: "Lets make to the man to our image, according to our likeness, and he dominate on the whole creation" (Gen 1,26).

This makes the man co-operator in the work of the creation. Co-Creative with God. An unavoidable command... a great responsibility.

The alchemist, spiritual in their being, delicate in their chore, understanding and meditating on this great responsibility, he begins to the service of the created Nature their abilities, perspiration and dedication so that continuing the steps of the Mother Nature, he could understand it and transform.

The alchemical laboratory has the same teams more or less that the chemical, except for some apparatuses of old design and classic that the alchemist prefers, not for nostalgy but for practical qualities, and of which we in their opportunity will be in charge of. For what we are able to and we should continue the same rules of praxis in security and manipulation that we would complete in a chemical laboratory. Nevertheless the alchemy is go further on... many further on that the operational or theoretical chemistry.

The secondary and practical object of the experimental alchemy is that the practitioner uses and understands the spagyrical operations, knowing their limitations and risks. That he check the properties of the diverse bodies and substances tried by the theoretical alchemy personally. That he recognize the interdependence of the amount of the substances with the dimensions of the team to use, the duration of the reaction, the conditions of agitation, cooling, purification and final amounts.

He should acquire and increase their manual know-how, approach and trust in order to select and mount the appropriate team in order to make the reactions, for brief that they are the available indications or if they lack, plan an original experiment correctly, choosing the solvent, temperatures and times of reaction more appropriate.

He should register their observations of methodical form, precise, complete, intelligible and reproducible.

Basic technique

Before beginning any execution, you will revise careful and thoroughly all the theoretical antecedents and mechanisms implied in the transformation, in order to foresee the special norms of security to use.

You should plan rationally the development of the experiment, meditating on the reason of each one of the steps of this, wondering:

1- Who is it the most probable mechanism of reaction?

2- That does it happens if do I change the amounts of reagents?

3- Why do I be supposed to use the experimental suitable conditions?

4- What does it happen if do rise or low the temperature of reaction?

5- Who is it the purpose of each step that I am giving?

6- How should I modify each step if do I want to increase or reduce the scale of the reaction?

7- How could one discover when does the reaction have been completed?

8- How do the secondary products of the reaction be eliminated?

9- Is there another alternative method for which could I achieve the same purpose?

10- What could quick and simple reactions use in order to continue the progress of the transformation?

11- Do I have identified and purified appropriately the product?

When you have to interrupt an experiment temporarily make sure that:

a- There won't be secondary reactions or of decomposition of the product before the experiment is renewed.

b- That they have been written down the names of their content and basic data of finalization like temperature, physical state, etc. in all the recipients.

c- That you in your journal of laboratory take registered all and each one of the details until the moment of interruption.

All solution, precipitate and obtained material, you should conserve until you have identified plenty, and you have been obtained the compound wanted with a reasonable amounts.

You will always act with caution, thinking over and don't leave the results of an experiment at random. Of not making it I sole will obtain frustration as prize, detriment in their health how punishment (for any accident) and economic loss how payment.

Don't play to the alchemist. You are able to that may be your last game.

Security

All the substances and materials that you use consider them like dangerous potentially

You always use glasses protectors and robe or apron.

You never smoke in their laboratory.

Always hot the volatile liquids in Mary's bath, of sand, of ashy or blankets, and under the extractor bell, never to direct fire and in close spaces and without ventilation.

You never direct the mouth of a recipient of reaction toward yourself or toward a companion.

You never leave spherical flasks that contain liquids in the trajectory of the solar rays, because it will cause a fire for the history mirror formed.

The stored ethers react with the air forming explosive peroxides. Detect their presence shaking in a tube of rehearse 1 [ml] of ether with 1 [ml] of recent solution of I iodide of potassium to the 10%. The presence of peroxides puts yellow the watery solution for the liberated iodine. The peroxides are destroyed washing the ether with a watery solution of Ferrous Sulphate.

Never hot close systems. They exploit.

You never use a reagent without reading the label carefully, observe their aspect and be sure of their origin and state of conservation.

You never throw water on alkaline metals or on salts or fused metals because one could cause an explosion. The remains of sodium or potassium should destroy adding them carefully ethyl alcohol or methyl alcohol. The litium, sodium and potassium should never leave exposed to the air. Especially the potassium, because it is been going to produce a fire. Manage them inside hydrocarbons (gasoline) and in dry places.

For lingering boils never fill the recipient to more than one third of their capacity.

Don't place liquids in a recipient to less than 1/ 3 neither more than ¾ of their total volume.

If you any doubt on measured of security or particular techniques, please let me know in an electronic mail and I with pleasure will guide you.
