Is your ceramics workshop a clean and safe space?

The distribution of tools and materials in our ceramics workshop is one of the most important factors in guaranteeing safe and clean work. If you have a large space, it is advisable to divide it into areas, each with a different function. In most cases, but -especially if you are just starting out in the world of handmade ceramics- it is more common to have a small, multifunctional space where you can carry out all the production phases. In the latter case, it will be necessary to organise yourself well, establishing a cleaning protocol to be followed every time you finish the day. 

Reduces risks

Remember that working with clay involves working with water, clay, powders, glazes (some with toxic components),…. Given that this activity involves materials that can be harmful to health, it is important that you try to reduce the risks as much as possible from the beginning.

Examine your workspace and put yourself in the shoes of the people who will be working in it: Are the aisles wide enough? Is there a risk of tripping over cables, machines or other items? Is there sufficient lighting? Is it possible to ventilate this space? Are materials properly labelled and closed to prevent spillage? Are shelves and tables strong and stable? Are materials available nearby for cleaning up during work?

It is a matter of giving a solution to each of these questions, so that you will know how to act in each situation in a safe way. 

Important health and safety issues to consider: 

• Work in as large a free space as possible, well ventilated and well lit. 
• The table or other work surfaces should be waterproof. Avoid supports made of porous materials (even for the workshop floor) so that they can be easily cleaned and impurities do not stick to them. It is advisable to opt for metal, plastic or other resistant and smooth materials, mainly for kneading, moulding and glazing clay. 
• Keep a sink with clean water nearby. This is where you can draw the water to work with and soak the cleaning cloths. Important: do not clean your hands or tools in the sink. Clay that gets into the pipes can clog them, which will end up costing you a lot of money to repair. It is better to opt for a bucket filled with water or decanting buckets, where after a while the clay particles will accumulate in the base of the container.
• Avoid smoking, eating, drinking or any other activity that may “contaminate” the clay. Also try not to generate more dust by quickly wiping off clay and engobe stains
• Wear aprons and wash them frequently, as well as your work clothes and shoes. 
• It is better to vacuum the floor and work tables in the ceramics workshop than to use a broom. Once the impurities have been vacuumed up, wipe with a damp cloth. 
• When working with powders (glazes, engobes, plaster for moulds, polishing process…) it is highly recommended to wear a mask and protective goggles. 
• Keep a first aid kit nearby so you can treat yourself if you get a cut or scratch.

Pay attention to toxic components

Some clays and dyes may contain highly toxic materials. In particular, you should use with caution those containing: antimony, barium, cadmium and lead. In the case of oxides to obtain colours, they should also be handled with great care. 

Nowadays, most manufacturers of ceramic clays and stains inform about these characteristics on the product labels. Even so, it is important to be sure of their composition and the risks involved in working with them. Ask the seller if you have any doubts as you are gambling with your own health and that of your customers. 

In the case of ovens, this toxicity may be present, especially if it is a shared oven. For example, materials containing traces of lead can only be used for decorative purposes, not for food use (e.g. cups or crockery). If lead was present in a previous bake, lead particles may be present in the oven. It is important to thoroughly clean the inside walls of this machine or, if you want to be on the safe side, use an oven that is only intended for baking food items. In this way, you will avoid cross-contamination.
