Arte Latino Prints
Artist and Title of Work: Judith Baca, Las Tres Marias (The Three Marys) (1976).
Technique and Materials: Colored pencil on paper, wood, cloth and mirror.
Size: 173.4 x 127.6 x 5.7 cm.
Courtesy: Smithsonian American Art Museum.
Acquisition: Museum purchase possible by W.T. Evans.
Comment[1]: Two strong women flank a mirror that serves to place the viewer at the center of the visual field. At left is a modern young chola (contemporary member of a street gang), dressed casually and gazing unflinchingly at the viewer, her hands in her pocket. At the right is a portrait of Baca dressed as a pachuca (member of a street gang from the 1940s) taking a drag from her cigarette. Through the updating of the centuries old theme of the three Marys of the crucifixion, Baca explores personal and cultural identity and challenges the viewers to position themselves - literally and figuratively - on such issues as gender, ethnicity and class.
Artist and Title of Work: Maria Castagliola, A Matter of Trust (1994).
Technique and Materials: Paper on fiberglass with cotton thread.
Size: 183 x 183 x 0.3 cm.
Acquisition: Gift of Artist.
Comment[1]: "There are very few relationships," the artist states, "in which you can share everything and trust that there is going to be support and understanding." Castagliola collected these secrets with the understanding that they were never to be opened. To ensure this, she sealed the quilt between sheets of fiberglass window screen. This added a formal element to her artwork, the padded surface shimmering with yet another pattern.
Artist and Title of Work: Maria Martinez-Canas, Totem Negro XVI (1992).
Technique and Materials: Silver print.
Size: 135.9 x 23.8 cm.
Courtesy: Smithsonian American Art Museum.
Acquisition: Smithsonian Institution Collections Acquistion Program.
Comment[1]: In Totem Negro XVI, carefully collaged signs and symbols give visual form to Martinez-Canas' feelings about being an exile. These fragments of ancient manuscripts, postage stamps, geographic forms, pre-Columbian temples, and maps reflect her struggle to reclaim her Cuban heritage. The collaged geographic and organic shapes are scratched and drawn upon, before being adhered to sheets of clear plastic that serve as handmade 'negatives'. Martinez-Canas then prints a limited edition of contact prnts on black-and-white photographic paper.
Artist and Title of Work: Delilah Montoya, Los Jovenes (Youth) (1993).
Technique and Materials: Collotype.
Size: 20.3 x 25.4 cm.
Courtesy: Smithsonian American Art Museum.
Acquisition: Donation by Horace W. Goldsmith Foundation.
Comment[1]: Montoya uses a 19th century collotype technique in which the negative is inked and printed, a process that blends photographic documentation and manipulation. Los Jovenes is a part of a series entitled El Corazon Sagrado (The Sacred Heart), a religious and cultural symbol that blends European Catholicism and Aztec philosophy. According to Chicano art scholar Dr Tomas Ybarra-Frausto, 'the heart has served as a symbol of resilience, bound both to visual iconography and to the process of creation itself' In this heartfelt work, Montoya has created a striking image of family strength - and love.
Artist and Title of Work: Vik Muniz, Sugar Children series (1996).
Technique and Materials: Silver prints.
Size: 35.6 x 27.9 cm.
Courtesy: Smithsonian American Art Museum.
Acquisition: Museum purchase made possible by the Horace W. Goldsmith Foundation.
Comment[1]: The power of the image lies in its ability to be underestimated. They're sweet simple things. You think you know what you're looking at," says Muniz, who wants the viewer to look anew at these representations. These prints asks the eye to question what it sees, posing a relationship between reality, truth, representation and memory.
Artist and Title of Work: Kathy Vargas, Missing #3 (1992).
Technique and Materials: Silver prints.
Size: Each 61 x 50.8 cm.
Courtesy: Smithsonian American Art Museum.
Acquisition: Museum purchase made possible by the Horace W. Goldsmith Foundation.
Comment[1]: Missing #3 consists of six hand-colored gelatin silver prints that the artist created through multiple-exposure photography. Together they create a haunting, poetic memento mori (reminder of cycle of life, death and resurrection). In this X-ray like image, a dark and lifeless bird is tucked into a band of clothing, feathers are strewn about, and broken twigs form an abstract pattern. The inspiration for the artwork came from a dream in which Vargas was lying in a coffin. As mourners paid their final respects, she was transformed into a bird. This is symbolized in the central panels, in which the bird and the skeleton merge. To the right, she said, 'is an image...waiting to wing out, but unwilling to walk for now.' Multiple hands appear, the palm in the upper left print mirrored by the skeletal one in the lower center. The hand colored image bears the artist's imprint throughout. An inscription on the back reads: 'At some point the two dreams merge into a recognizable self-portrait.'

Introduction
In the digital world of today, playing with designs on a computer that hosts an array of different applications (such as photoshop etc) one can easily create new fabric designs. There are companies, such as Spoonflower, which can then recreate the designs on an array of different fabrics for functional use (e.g. tablecloths, napkins and dresses) to create more Indie clothing selections and/or for artistic expression - see for example - My Fabric Collection: "Oh, Oh Marilyn and Mona!"@Spoonflower. The digital world allows our imaginations to run wild and so if by design or by accident we create a design that inspires us as well as others - so be it!
Now is the right time to remember the inspiration that Kristi O'Meara tried to document in her book and so why not look at her contribution to the world of abstract geometric designs.

Woolen Stripweaves of the Niger Bend[1]
Apart from the area around Cape Verde, the only region in West Africa with climatic conditions suitable for rearing sheep is the Niger Bend. It is cool and has enough pasture (from the flooding of the Niger).
Blanket "Mumuye" from the Fulani people of the Niger Bend region, Mali and Niger.
Woven with white sheep's wool on a horizontal strip loom, they are made up of four to six panels, each approximately 15 cm (6 inches) wide, sewn selvedge to selvedge. Each strip has supplementary weft decoration, with motifs influenced by North Africa. The Fulani name all different motifs. The designs on the upper and lower borders symbolize water and fertility, while the central motif represents the paths taken by the Fulani herds. The strips are sown together so that the 'Moorish' motifs join up to form lateral bands of pattern.
Part of an old arkilla kerka woolen cover woven by the Fulani for the Tuareg.
Itinerant Fulani weavers travel to Tuareg encampments to weave very large chequered tent dividers or bed covers known by such names as arkilla jengo and arkilla kerka. Like khaasa, the warp is made of cotton and the weft of wool. The combined thickness gives not only warmth at night but also protection from the abundant and troublesome mosquitoes. Arkilla are bought by rich Fulani, marabouts (holy men), nomadic Tuareg and Moors.

Sheep are shorn by Fulbe (noble-caste) Fulani shepards. The wool is spun by women and given to Maabube (lower-caste) Fulani weavers, who weave it into khaasa strips. Sewing together the strips and finishing are tasks carried out by the Fulbe. The same process takes place when the Maabube weave for the Tuareg, though the wool is Tuareg.
Khaasa Fulani woolen blanket, Mopti, Mali. Berber weavers in southern Algeria weave very similar textiles, which may be a model for the khaasa or an export-driven imitation.
According to the acknowledged expert on the subject, Dr Pascal James Imperato, Fulani looms are made up of twelve pieces of wood. Four are driven vertically into the ground. The cotton warps are tied around a stone drag weight on a wooden or metal sledge. From the anchor, the warp passes over a beam and down through two foot-operated string heddles, which are hung from a wooden pully assembly through a reed-beater and end around a cloth beam.

All data bases will be updated from time-to-time in the future.
If you find any post on this blog site useful, you can save it or copy and paste it into your own "Word" document etc. for your future reference. For example, Safari allows you to save a post (e.g. click on "File", click on "Print" and release, click on "PDF" and then click on "Save As" and release - and a PDF should appear where you have stored it). Safari also allows you to mail a post to a friend (click on "File", and then point cursor to "Mail Contents On This Page" and release). Either way, this or other posts on this site may be a useful Art Resource for you.
The Art Resource series will be the first post in each calendar month. Remember - these Art Resource posts span information that will be useful for a home hobbyist to that required by a final year University Fine-Art student and so undoubtedly, some parts of any Art Resource post may appear far too technical for your needs (skip over those mind boggling parts) and in other parts, it may be too simplistic with respect to your level of knowledge (ditto the skip). The trade-off between these two extremes will mean that Art Resource posts will hopefully be useful in parts to most, but unfortunately may not be satisfying to all!
Introduction
Sulfur dyes are so called because they contain sulfur (S) atom(s). Sulfur dyes have been used as cotton dyes for over 100 years. The range of sulfur dyes is limited to dull colors from yellow to black. None are very bright and reds are almost absent apart from a few dull maroons and bordeaux shades. The fibers that are most readily colored with sulphur dyes are the natural and man-made cellulosic fibers.
Sulfur Dyes. See - http://www.alibaba.com/product-gs/442451744/sulfur_dyes.html - for further information about these dyes.
Little is known about the chemical structure of sulfur dyes, even though they are thought to contain a thiazine ring.
Portion of a sulfur dye molecule.
Note: The complete structure is still not known. The thiazine ring is the –N=C-S- portion of the above structure, where N, C and S are nitrogen, carbon and sulfur respectively.
Courtesy of reference[1].
Sulfur dyes are water insoluble and so must first be reduced into a soluble form. They are produced by chemically reacting compounds as p-aminophenol and dinitronaphthalene with sulfur. A simplistic scheme for their production is given below.
Production of a sulfur dye.
Note: The old spelling of Sulfur is used in this schematic.
Courtesy reference[1].
Dyeing with Sulfur Dyes
Sulfur dyes are insoluble in water. An aqueous solution of the sulfur dye is effected by reacting some sulfur dyes with sodium sulphide and others with sodium hydrosulfite. The role of sodium sulfide or sodium hydrosulfite is to reduce sulfur to produce the water soluble or leuco form of the dye. In some instances the addition of sodium carbonate may be necessary to achieve the desired alkalinity. In this reduced or leuco form, sulphur dyes are substantive to cellulose fibers. To achieve dye exhaustion, it is necessary to add an electrolyte such as sodium chloride to the dye liquor.
To obtain adequate penetration and a satisfactory rate of dyeing, the dye liquor is heated. This has a two-fold effect:
(i) It enlarges the entry and internal voids of the amorphous regions of the fiber polymer system enabling deeper penetration into the fiber.
(ii) It increases the kinetic energy of all the constituents, thereby increasing the rate of dye uptake by the fiber polymer system.
Once the dye is within the amorphous regions of the fiber polymer system, the reduced sulfur (which is soluble) is converted to its original insoluble form, via an oxidation treatment with a mild reagent such as sodium perborate.
Printing with Sulfur Dyes
Sulfur dyes are generally not used for printing textile materials.
Properties of Sulfur Dyes
Light-Fastness
The light-fastness rating of sulfur dyes is about 4, which translates as fair. After-treatments with metal salts improve the light-fastness rating to 5. The initial fair rating is attributed to the instability of the chromophores of the sulfur dyes with respect to UV sunlight. On the other hand, metal ions improve the stability of the sulfur dye chromophores with respect to UV sunlight, increasing their light-fastness rating.
Wash-Fastness
Sulfur dyes have a wash-fastness rated between 3-4, which is fair due to the relatively large size and partly to the aqueous insolubility of the dye molecule. The general lack of any significant polar groups in the dye molecule implies that the dye is retained in the amorphous regions of the fiber polymer system due to its size, aqueous insolubility and van der Waals forces of attraction.
Color Range of Sulfur Dyes
Sulfur dyes have a color range, which is limited to black, brown, blue and olive. Sulfur dyed textile materials are also dull. Their dullness can be attributed to the greater scattering of the incident white light, possibly due to aggregates of the dyed molecules trapped and entangled in the amorphous regions of the fiber polymer system.
Bronzing
Sulfur dyed textile materials show a metallic or bronze sheen, which is termed bronzing. This effect gives rise to poor rub-fastness, and moreover, gives the textile material a less appealing appearance. Bronzing mostly occurs in heavy or dark shades for the following reasons or combinations thereof:
(i) Exposure to excessive heavy dyeing.
(ii) Exposure of the textile materials to atmosphere during dyeing causing premature oxidation.
(iii) Failure to remove excess dye liquor following dyeing.
(iv) Providing an insufficient amount of sodium sulfide in the dye liquor to keep the dye in its soluble form.
The bronzing effect can be removed by an after-treatment in an aqueous solution of dilute sodium sulfide, which will remove excess dye molecules that are present on the surface of the textile material.
Cost of Sulfur Dyes
The relative low cost of sulfur dyes has meant their continued use particularly for dark colors, such as navy and black.
