Donna Van Hooser

Donna was inspired to make mosaics after visiting the St. Louis Basilica in 1991 while working as an artist for Hallmark Cards. With her background in illustration, she tries to incorporate storytelling in her mosaics, using classical and whimsical elements.
She learns and grows through experimentation, often finding inspiration from the materials themselves. In 2015 she retired from Hallmark Cards after 27 years. She moved to Arizona and began making mosaics full time as well as teaching workshops around the country. "I love working in mosaic, especially dealing with the challenges and limitations of the materials. The glass must be carefully chosen from a limited palette, since colors cannot be mixed, and each piece must serve as an individual brush stroke working in harmony with the surrounding pieces."
Donna's Classes
In this class we will use greyscale values rather than traditional colors to create form and expression in creating a mosaic pet portrait. Precision cutting techniques will be covered, as well as andamento, glass selection and shading. Since this technique is more time consuming, a finished portrait is not expected at the end of the three-day workshop, however, the eyes and a good portion of the face can be completed, depending on the experience of each student. This workshop is intended for intermediate or advanced mosaic artists and should not be used as an introduction to making mosaics. Students can either work on a black and white photo provided by the instructor, or can provide a PHOTO prior to the class. Photos provided by the students should be high resolution showing good detail (not out of focus) and have fairly strong contrast between values. The instructor will map out the design before the class if using a photo supplied by the student prior to the class. A phone with a camera is recommended, as we will be using this as a tool in class to see grayscale values.

John Ferrando

First and foremost I am a family man. A husband and father of 5. In what spare time I have from my first love, (my family) I am an artist/instructor working in kiln-formed glass.
My glass kiln gets just as much miles on it as my Toyota Sienna van does driving the kids to sporting practice, dance rehearsals, school, etc. As a glass artist who has been fusing and working with the medium for 8 years +, I have spent countless hours exploring, experimenting, testing , and pushing the medium of glass to its limits to see how far I can go in creating something unique and pleasing for the art enthusiast. Previous positions and experience, I recently held a County position for a non profit Art Studio, serving artists with various developmental disabilities. As an instructor and teacher in the studio, I taught multiple artists with developmental disabilities the art of creating with and working in fused glass. It brought me pleasure to spend years investing my time, talent and experience into those artists, empowering them to become the successful artists they are today. Their work has been exhibited in galleries and venues all over the tristate area, sold in gift shops and art boutiques, as well as at fine art and craft fairs held locally throughout the year. Allowing the artists to be able to make a profit and income from their work. My body of work would be best defined as creating a constantly evolving range of decorative glass design. My current range is focused on sheets of glass and stringer strips made of glass to produce work which has undulating decorative motif art effects. One of my passions is spending hours in the studio experimenting with the glass medium and developing exciting ways to work with all the different materials. I enjoy the competition of entering my glass art into juried exhibitions and gallery shows. I find it gratifying watching others enjoy, appreciate and experience my work. I adore creating one of a kind pieces for sale in galleries and Art Fairs. As well as educating fellow glass artists of different fused glass techniques. More recently I am the author of a popular selling fused glass ebook which showcases unique techniques in Kiln Formed Glass. In my writing the ebook, my aim is to provide artists of all skill levels with ongoing support and education to assist in developing those artists skills. I hope to be able to reach glass artists around the world whom i other wise would not have the honor or pleasure working with in my studio, Haute Fusion Studio, in Middletown,OH. The procedure and practical skill taught in my Ebook is conducted using my own methodology and knowledge, which I have no doubt differs from others being taught by several different artists, nor will the end product be the same. I have no doubts that other artists techniques have their benefits, as does mine that I teach in my book; there is no harm in exploring and sharing popular processes.
John's Classes
Delphi Creativity Center is pleased to welcome Visiting Instructor and Kiln-Form Glass Artist John Ferrando for this three day workshop. John will provide comprehensive, in depth instruction that will enable each student to leave with a one of a kind, gallery quality piece of art. As well as a complete comprehension of the techniques and methodology for the ability to recreate these processes on their own upon returning to their home studio. During this workshop, participants will learn an advanced and unique stringer technique based on John's popular selling ebook, "Decorative Motifs with Fused Glass". While creating undulating designs with the use of glass strips, participants will also be exploring color theory, design composition, the use of materials and supplies, as well as the various firing schedules required to create a finished Motif. Additional projects using the class materials will be taught as time allows. *Glass cutting experience required.

Joy's Classes
Flameworking guest artist Joy Munshower is back at Delphi to teach this new extraordinary class; hedgehogs, dragons, chickens and giraffe in bas-relief. This workshop is for intermediate and advanced students. Students will be sculpting bas-relief style beads with an emphasis in surface texture detail and cane application. Students will learn how to sculpt Hedgehogs, Dragons, Rooster/Hen and a Giraffe from both photo reference and instructor-drawn examples. Students will learn how to break down the shapes of these animals and how to apply those shapes to sculpting in a bas-relief or low-relief style on a base bead. Students will also learn how to make complex canes and how to apply those to mimic "quills, scales and feathers". A Giraffe will be taught to teach the students how to apply a coat pattern and how to create realistic wrinkles and hair texture. Students will also learn how to use specialty tools and scalpels to facilitate and ease sculpting in a low-relief style as well as in 3-D. Some photo and diagram reference will be provided to the students to better illustrate shape, anatomy and composition breakdown.
