What is Glass on Glass (GOG) Mosaic Art?

What is Glass on Glass (GOG) Mosaic Art?

Glass on Glass Mosaics is essentially glass, usually stained glass, glued to glass and then grouted, using sanded grout. Mosaics are durable they can be put together to last a lifetime and beyond, if proper steps are taken.

More specifically, what does art mean to me (Kory Dollar); why do I create and teach with such passion?

To me Glass on Glass is my story, my lifeline, my legacy, my drive, and passion.

What makes my teaching style unique?

I have a specific cutting style, rules, and guidelines established to push myself and my students beyond our artistic realm. I will open your eyes to how glass breaks and why it breaks the way it does. I have simple rules to follow and if you want to break them that is okay too! I will teach you process and style, while having a great time and creating epic art. I can explain how and why. I provide excellent visual aid. My teaching style will adapt to any learning style.  I provide hands on, visual aids, verbally express the steps, and provide detailed handouts.

The snow will melt, but this memory will last forever! This photo reminds me of why I love glass on glass. It takes me back to childhood, the creative bonds I established between my parents and the environment. It is the freedom to use any materials around you just to create and it doesn’t have to be good it just needs to be done! Creating art is expressive, healing, and emotional. A gift to understand how using your materials can create life long memories, not just art. Art that disappears can even make the most memorable impact to keep creating in adulthood. From the moment we are born our brain is building synapses that make us happy and art has always done that for me! I believe that because of the artistic environment I grew up in art keeps me happy; it reduces my anxiety, reminds me of wonderful times spent creating from our materials! If the universe gives you snow make a colorful snowman.

What is so different about Glass on Glass Mosaics?

Using the process I have developed, Glass on Glass Art, will out last the test of time. I know that not only am I creating lifetime art, I am inspiring others to leave a healthy artistic footprint behind too.  I teach how to build/create a lifetime piece of fine art. I believe you are only around as long as your memory and that is essentially why I create with such passion. I know my Great Great Great Grandchildren will see my art, making my existence on earth transcending. I want to leave a healthy artistic footprint, to out-stand the test of time; and that is what makes GOG so special to my heart.

I am proud to promote “artistic freedom without self-doubt,” in my students and children. This photo of the best snowman EVER in Lily’s world! It reminds me why I teach my trade to others; Glass on Glass is very powerful; it is a trade I have developed and built throughout my artistic journey,  my life. My work is inspired by tile work, mosaic, sculpture, painting, pottery, woodwork, glass blowing, and my environment I was raised in. I was always at my dad’s hip waiting to create. My mother always talked about designing in odd numbers, numerology, and feng shui in our home. My most cherished possessions are what my father, grandfathers, and children have created. I feel a passion to teach and create, to leave behind my memory, and give my students that gift as well!

GOG is like no other art, not even stained glass. The details and depth can mesmerize me for hours! It is freedom in a cup! Glass on Glass has so many artistic element’s that a painting or any other medium can not offer. GOG is a variation transparent, opaque, iiridized glass, combined with unique elements like texture, reflectivity, illumination, and prismatic colors. Glass on Glass Mosaics have LIFE and can heal the sole! I am proud to say that lifelong friendships are established through our mosaic community and human connections are so important  to promote happiness and build confidence. Glass on Glass Mosaic can also offer an ever-changing piece of illuminated art, essentially changing with the light of the sun.

Photo is of Lily Lathrop, my only niece. My dad, sister, I once made a colored dragon, a snow chair, and many snowmen! Last year, my son and I filled bottles of water and food coloring and had fun splattering the neighborhood!

Three and a half days in the lush Oregon countryside, making mosaics with old and new friends.  Pitch your tent (or bring your trailer) and pack a cooler.  Enjoy open-studio time to work on your projects and class sessions led by Kory Dollar.  Work late in the studio, gather around a bonfire, go for an evening hike, or enjoy a outdoor summer massage. This is just one of the many joys that we will have available for our summer mosaic camp out.

About the Helvetia Lavender Farm:

Helvetia Lavender Farm, nestled in the hills overlooking the Willamette Valley a short drive from Portland, demonstrates the versatility of lavender with 60 different varieties in landscaping and cutting fields. Students are welcome to wander through the gardens, enjoy the view from our pavilion, and relax amid the many spots to relax and enjoy the scent of lavender.  There is a beautiful pond on the property and a fantastic fire pit. We will have access to the pavilion where you can have drinks at sunset with your new friends, and enjoy the beautiful outdoor setting. The Pavillion is nestled in the trees and gardens overlooking rolling hills and the Cascade Mountains.

Food and Beverage Details:
We will have water, coffee and tea for you to drink, if you want alcoholic beverages you must bring your own. We will provide a barbecue for everyone to use at anytime.  We will provide the main dishes for Thursday, Friday, and Saturday evening. There will also be meats, cheeses, veggies, breads, and condiments for you to make a sandwich at anytime. We are asking everyone to pitch in with side dishes, pastries, fruit, salads, and other snacks to share through out the weekend. If you want to bring paper supplies, instead of food that is also an option too. We are planning a nice sit down dinner Friday evening and a  barbecue Saturday night. This is a camp out not a retreat, everyone will be expected to help participate in meals and clean up.

Camping Details:
There is hook up for power and water, if you are bringing a trailer. You must be self-contained. There is no dump station or gray water disposal. We will be limited to the number of trailers, so please let us know the size and type of trailer when you register. If you have extra room in your trailer and want a bunk mate we have students that are looking for a bed.

We have a lot of camping spots with sunset views! Arrive early to set up your tent and get your spot. We have ONE shower on site, there will be a sign-up schedule to use. We assume with keeping the numbers low and having showering schedule it should not be an issue.  There are two bathrooms in the workshop and a few porta potties on site.

We do have 2 loaner tents, one very large that is a 10-man we will be setting up and one 5-man tent. If you want to bring an air bed and a sleeping bag you are welcome to sleep in them but we will most likely limit the 10 man to 4 women and the 5 man to two women, so let us know a head of time if you need to sleep in the tent.

30 Min Massages will be available for an additional cost of $30. Please let Denny know when you register, if you would like to schedule one.

Kory will demonstrate and discuss a specific nipping style /technique, Glass Shaving® to create a crisp clean edge, using only wheeled nippers. The class will explore how to create movement, using Kory’s signature cut, One-cut Sliver Cut®. Additional topics covered include: committing to a design, selecting a color pallet, varying opacity, Randomization Method®, balance and composition, creating a one-of-a-kind designs, and incorporating found and unusual items. Kory will discuss grout bleed, adhesives, grout additives, and provide tips and tricks to grouting. Mac glue and any other adhesive required will be provided. Students are encouraged to bring additional unique items such as broken jewelry, beads, and tesserae to embellish your mosaic.

There will be a grout demonstration on Sunday. Students are welcome to grout if they have completed the project and glue has dried. If projects are not completed, or dried by 2 pm then a grout package will be available to take home for optional grouting.

Kory notes that she does not strive for perfection; “the art of art is the imperfections.” She says, “It is my goal that I will simplify the process enough to give you ‘artistic freedom without self doubt’. I strive to build confidence in these classes. I do not teach from a pattern, I teach to use your sketch as only a guideline; you are not restricted to the pattern. I will assist you in creating a balanced one-of-a-kind composition, using my uniquely designed simplified steps. We will focus on several unique cuts and I will provide you with tips and tricks that I use daily.”
