Introduction :
Since substituting for complex raw ceramic materials involves calculation that many potters are not familiar with and since we have found a way to substitute for most of these we offer to the community of ceramists the results of our research.
This research project originated very spontaneously while calculating to substitute for spodumene by lithium carbonate, kaolin and silica. Our approach is for those who are not familiar with glaze chemistry or for those who do not own a computer. This research project was conducted between 1993 and 1995, before the popularization of computer glaze softwares and home personal computers. Even at the present time only 20% of Quebec households own a computer and only 6% of them have a link to Internet (1997).
After succeeding our first substitution for spodumene the results were sent to W. Hunt, editor with Ceramics Monthly, who really appreciated our method. His letter of May 19, 1993 was a real boost for us: “I appreciated you sending us this fascinating discussion on substituting for spodumene. With your permission, I’d like to use parts of this in our Letters column”. Then we decided to apply our method to the substitution for feldspars, felspathoids and other raw materials, as you will see later. The results were sent to W. Hunt on a slow basis, in a “chapter by chapter” like manner, as new hypotheses came to our mind. Then on March 17, 1994 he send his final comments on what we had sent thus far. The chapter on lepidolite was done after receiving his last letter but the same methodology was applied.
We used general formulas rather than complex analysis and carried 3 decimal places, rounding the fourth on the third. We used the notional oxide KNAO. We also used a few other personal tricks. Our goal was to obtain substitutions in which new unity formulas were the closest possible to the original ones, which we achieved on each occasion.
Since the formulas of feldspars and feldspar-like materials are somewhat similar to those of glazes we used this last principle to find adequate substitutions. The idea was to consider the complex materials to be substituted for as glazebase unity formulas to be converted to batch recipes, then they were divided by 100 to be inserted easily in glaze recipes.
According to the method for glaze calculation: “Glaze calculation, theory and objectives”; “Glaze calculation using materials containing more than one oxide” and “Calculating glaze formulas from batches or recipes” (Daniel Rhodes, Clay and glazes for the potter, revised edition, 1973) we used different materials to achieve our goal which was to make a mixture having, once fired, the formula of feldspars and feldspar-like materials.
Naturally some minor adjustments had to be made, by the method of trials and errors (on a mathematical basis), to the results of the first try (first substitution) to obtain a satisfactory fit. Then when necessary and/or possible, the results of the second try (second substitution) were tested a few more times in different recipes to eliminate possible good results due solely to chance.
Finally we applied our method to materials far less complex than feldspars and feldspar-like materials.
Sincerely
Edouard Bastarache

Dear Mr. Bastarache:
We are truly amazed at all these submissions that you have sent concerning ceramic materials substitutions. I can’t think of the last time someone sent us this much data – enough for a substantial book. These texts go beyond anything we could publish in Ceramics Monthly, so I’m wondering if you’d allow us to post these in our research library where the staff or other potters visiting the library would have access to your research. Of course, if you would rather us return this material to you we would, should you request it.
I thank you for thinking of us with all your detailed and thoughtful research; I look forward to hearing from you further as to its disposition.
Sincerely,
William Hunt

Thank you so much for sending the books with Michel. They are
amazingly thorough and fill an important void in my library. As both
potter and educator very concerned with the use of materials it is
great to have them. I have known about them for some years, but, as I
will soon be slowing down on the teaching end of things, hadn't got
around to getting them. When Michel was coming for a visit and
sometimes works in your studio, it seemed like an ideal time to add
them to my library.
Much appreciated, thank you.

Invaluable resource
I have to admit, when I bought this book, part of my reasons were to
support an online friend and fellow clayarter, by adding his book to my
collection. It was very pleasant to receive the book and realize what a
wonderful addition to my clay book library it is! I wanted to share my
reactions by sending my review.
Being a potter who mixes glazes from scratch, I sometimes will go to make
up a recipe and realize that I'm missing one of the ingredients or don't
have quite enough. This book is an invaluable resource for such a
situation where quick re-stocking of chemicals is not always an option.
The book is arranged by chemical being substituted for, with variations in
the ingredients used as replacement. Monsieur Bastarache has generously
shared many recipes, showing a sample substitution for each variation.
Potters are known for sharing glaze recipes and in this age of electronic
communication, many recipes are being shared online far and wide around the
world. Some of the glaze ingredients are not available in all parts of the
world, without exhaustive shipping costs.With this book as resource,
potters in areas where some chemicals aren't common can easily substitute
and get similar results on their clay pieces.
The book is spiral bound with a good quality cover for convenience and ease
of use in the studio. I would like to commend Edouard for creating this wonderful
reference.

A tribute by a friend
Dear Édouard,
Most sincere congratulations for the realization of your book. It is really the results of a maniac of research, a mad one about ceramics like there is no one else in Quebec. I have read with pleasure your new book and it was for me a return on my past as a technologist of ceramics. I am thus happy to share your joy of this publication, that will incite ceramists who prepare their glazes, to launch out towards creative adventures of new shades and colors. As for the cover of your book, accept my congratulations because it is a very beautiful.
HEARTY CONGRATULATIONS AND GREETINGS

Tour de force
Edouard Bastarache's book « Substitutions for Raw Ceramic Materials » is a 'tour de force' of substitutions of particular ceramic materials with others. The book is the result of a research project undertaken between 1993 and 1995 before computer glazing programs became widely available and is targeted to those ceramic artists and potters who don't have computer access to help them with otherwise complex calculations in materials substitutions.
This is a comprehensive publication on glaze materials substitutions and includes 10 chapters filled with glaze recipies using the sustitution method. Both the original and substituted recipies are provided. Materials substituted include Spodumene, Petalite, Lepidolite, Potash Feldspars, Cornish Stone, Sodium/Calcium Spars (Kona F-4), Potassium/CalciumSpars (G-200) , Plastic Vitrox, Volcanic Ash, Dolomite, Wollastonite, Pryophyllite and Talc. Three hundred pages contain several hundred glazes. In a typical glaze materials substitution, Custer Feldspar might be substituted by Nephelene Syenite and Silica, or Spodumene by Lithium Carbonate, Silica and Kaolin, etc.
Edouard Bastarache lives in Quebec, Canada, and has a colorful history. He studied surgery, internal medicine and neuroendecrine physiology and has been a consultant in occupational and environmental medicine for 25 years. At the same time as his medical studies, he studied ceramics under Julien Cloutier at La Boutique d'Argile (The Clay Shop) and later also taught at the same school. Bastarache now lives in the Sorel-Tracy region of Quebec, near the St. Lawrence river. He uses waste materials from steel plants located in the area to color many of his glazes and clays. He fires most of his work to cone 9 1/2 in reduction in a 60 cubic foot downdraft gas kiln.
His book Substitutions for Raw Ceramic Materials is the result of a total of 38 years dabbling in ceramics and a 3 year research project.

Hello Édouard,
The more I learn about the world of potters, the more I think that your idea to write a book on raw materials substitutions is brilliant. None or only a few potters calculate or convert mineral chemical formulas. It must annoy them to calculate, or then they do not know how.

This statue at Bryant Park was given to the people of New York by Brazil.
José Bonifácio de Andrada e Silva (June 13, 1763 – April 6, 1838), was a Brazilian statesman, naturalist, professor and poet, born in Santos, São Paulo, then part of the Portuguese Empire. He was of the most important mentors of Brazilian independence, and his actions were decisive for the success of Emperor Pedro I. He supported public education, was an abolitionist and suggested that a new national capital be created in Brazil's underdeveloped interior (effected over a century later as Brasília). His career as naturalist was marked by the discovery of four new minerals.
In 1800, Andrada e Silva was appointed professor of geology at Coimbra, and soon after inspector-general of the Portuguese mines; and in 1812 he was made perpetual secretary of the Sciences Academy of Lisbon (Academia das Ciências de Lisboa). Returning to the colony in 1819, he urged Dom Pedro I to resist the recall of the Lisbon court, and was appointed one of his ministers in 1821. When the independence of Brazil was declared, Andrada e Silva was made minister of the interior and of foreign affairs; and when it was established, he was again elected by the Constituent Assembly, but his democratic principles resulted in his dismissal from office, July 1823.
On the dissolution of the Assembly in November, he was arrested and banished to France, where he lived in exile near Bordeaux till, in 1829, he was permitted to return to Brazil. But being again arrested in 1833, and tried for intriguing on behalf of Dom Pedro I, he passed the rest of his days in retirement at the city of Niterói. He was also the author of the abolition project in Brazil presented to the Constituent Assembly in 1823. José Bonifácio spent part of his life in Europe. Graduated in Law and Natural Philosophy in Coimbra, he joined the Academia das Ciências de Lisboa (Science Academy of Lisbon).
In his trips around Europe he studied chemistry and mineralogy with other scientists. He collected data, made scientific experiences and discovered 4 new minerals and 8 types of unknown species. The mineral andradite is named after him. Among his other discoveries was Petalite, a lithium-containing material, first discovered by Andrada toward the end of the 1700s on a trip to Sweden, and it was in this mineral Swedish chemists first discovered lithium. He also was the first to discover another important lithium-containing mineral spodumene from the same source, an island near Stockholm.
He taught Geognosy at the University of Coimbra in Portugal. Knowing twelve languages he could speak four.
In 1819, he travelled back to Brazil where he continued to conduct scientific research. A talented man having an unquiet temperament was also he was appointed to be the head of the Ministry for Kingdom and Overseas Affairs.
His relationship with the prince became incompatible and he decided to join the opposition. In 1823 he was exiled and went to live in Bordeaux where, in 1825, come out his "Poesias Avulsas" (Sundry Poetries). To publish them he used the pseudonym Américo Elísio. José Bonifácio came back to Brazil in 1829. In 1831 when Dom Pedro I abdicated from the throne, he was appointed by the former Emperor to be the tutor of the Emperor's sons. Since he did not agree with the Regent's government he tried to reestablish the Empire. In 1833 he lost his duties of tutor and was accused of being a traitor, but he was eventually pardoned. He died on April 6, 1838 in Niterói.
José Bonifácio had also been engaged in Literature. His work Poesias Avulsas that come out in Bordeaux were republished in Brazil, in 1861, by the publisher Laemmert. In Brazil it received the title "Poesias" (Poetries) and the publication had the coordination of Joaquim Norberto de Sousa. In 1942 Afrânio Peixoto prepared another issue through the Brazilian Academy of Letters. This work, prefaced with a text by Sérgio Buarque de Holanda, was also published in a collection, as Volume I, idealized by the "Instituto Nacional do Livro" (The National Book Institute), appearing in 1946 with the title Poesias de Américo Elísio [Américo Elísio's Poetry]. His poetry shows a naturalistic pantheism that expresses his intellectual character and scientific curiosity.
His Scientific, Political and Social works are published in Volume III, compiled and reproduced by Edgar Cerqueira Falcão with the title Obras científicas, politicas e sociais de José Bonifácio de Andrada e Silva. Its third edition came out in 1963 to celebrate the bicentennial of the Patriarch of the Independence.
In 1797, he was elected a foreign member of the Royal Swedish Academy of Sciences.

Artork by Jonas Nobel. Called Li, or Lithium. The sculpture was made from concrete and aluminium. Lithium was discovered on the island of Utö in Haninge two centuries ago by José Bonifácio de Andrada e Silva. Well he found Petalite, and a few years later J.A. Arwedson discovered the Lithium. There's even a Lithium Day on the island of Utö on November 18 since a few years. There's two other sculptures in the series and the big opening takes place this coming Saturday.
base: Neph 40%, Whiting 30%, Flint 30%
#1: added Cu 2%, Petalite 8%
#11: added Co 1%
#15: added Rutile 12%
All gradients are from 0 to the max listed above. IE, #15 had 12% Rutile, but 1, 2, 4, 7, and 11 had none. If you're not sure how that works, Google can help you!
Also, note that the image isn't particularly accurate as to color, and texture is totally missing! This isn't a replacement for actual test tiles.
