Sodium Carbonate Toxicology
By Edouard Bastarache
Identification and Uses
:
CAS Number : 497-19-8
Molecular Formula: Na2CO3
Uses and sources of
emission :
- Manufacture of soap, softening
agents,
- Ceramics.
Toxicology
:
This product is absorbed by the
respiratory and digestive tracts.
Acute effects :
I-Ocular Contact :
Irritation of the eyes.
II-Inhalation :
Irritation of the higher respiratory
tract, pulmonary irritation.
III-Ingestion :
- Irritation and corrosion of the mucous
membranes of the gastro-intestinal tract,
- vomiting (may contain blood),
- diarrhoea,
- abdominal pain,
- collapse,
- death.
IV-Skin Contact :
It can cause redness, oedema.
V-Aggravation of Preexistent Medical
Conditions :
The inhalation of the product can worsen
preexistent respiratory problems such as asthma, emphysema and
bronchitis.
Skin contact can worsen a preexistent
dermatitis.
Effects on development
:
A study on several animal species
suggests the absence of effects on antenatal development.
Effects on reproduction
:
No data concerning the effects on
reproduction has been found in the consulted documentary sources.
Data on mother's milk
:
No data concerning its excretion or
detection in mother's milk has been found in the consulted
documentary sources.
Carcinogenic effects
:
No data concerning a carcinogenic effect
has been found in the consulted documentary sources.
Mutagenic effects
:
No data concerning a mutagenic effect
has been found in the consulted documentary sources.
First aid
:
I-Ocular Contact :
Rinse the eyes with water for at least
15 minutes. Seek medical help immediately.
II-Inhalation :
Bring the individual into a ventilated
place and make sure he is still breathing. If there are
respiratory problems, give oxygen if there is any available. If
the victim does not breathe, give him artificial respiration. Call
a physician.
III-Ingestion :
If the individual is conscious, make him
drink water. Do not give anything by mouth to an unconscious
person. Do not induce vomiting, call a doctor.
IV-Skin Contact :
Quickly withdraw contaminated clothing.
It is necessary to wash skin with water and soap during 5 minutes.
Seek medical help if irritation develops.
Stability
:
This product is unstable under the
following conditions: it absorbs humidity from air (hygroscopic).
Moreover, there is formation of hydrates from contact with
humidity.
Handling
:
Wear ocular protection. Avoid any skin
contact. Ventilate adequately, if not carry a suitable breathing
apparatus.
Storage :
Store in an airtight container placed in
a dry place. Do not store in a container made of aluminium or
zinc.

The future of ceramic recipe, material and physical testing record keeping is here.
Maintain your recipe database on-line
- Login to a private account or work with others in a group account (e.g. university).
- Nothing to install (access it using your web browser). It is always the latest version.
- Easy to import your existing data.
- As many side-by-side recipes as you want.
- Many ways to search and classify glaze and body recipes.
- Glaze and body recipes are robust, with units-of-measure, unlimited pictures with individual titles and descriptions.
- Add variations to a recipe; each with its own pictures, descriptions and name/code-number extensions.
- Recipes can link to typecodes, projects and firing schedules (all managed in their own areas).
- Standard reports and mix ticket reports with last-minute-totalling; variations report as if they are a complete recipe.
- Video tutorials, help system, contact form on every page, dedicated messaging and support ticket systems.
- It is an industrial-strength database system (unlimited capacity, fast, reliable, scalable).
Imports many file formats
- Glaze recipe formats supported: HyperGlaze, GlazeGhem, GlazeMaster, Matrix, INSIGHT XML recipes (single and multiple), INSIGHT SQLite DB files.
- Assign a batch number to imports, and later search by batch.
- Assign multiple typecodes to imported glaze and body batches (to classify) and search on these later.
- Prepend character sequences to glaze recipe names during import.
- Import the pictures and pair them to their corresponding records automatically.
- One click to automatically export the database to an SQLite DB database file and download it (for use with desktop INSIGHT or just as a backup).
- Export and import individual glaze recipes as text or XML.
Perfect for Education
- Ceramic study programs can now accumulate material, recipe and testing data year-after-year, students can login and together build a valuable ceramic glaze and body knowledge resource.
- Students already have internet connected devices, computers are not even needed in the class.
- The Reference Manager gives you quick access to the Digitalfire Ceramic Reference Database.
