I have attended 2 workshops with them-- one glass fusion and the other glass blowing (pumpkin making). I had a superb time on both occasions. The glass fusion workshop involved creating a mosaic pattern of one's choice from shards of colorful glass positioned on a large slab of clear glass. The glass slab could be used as a whole, or partioned into three long sub-slabs. The pattern is then baked by the experts in a kiln and the resulting fused conglomerate is ready for pick up in a few days. I chose the three sliver style, one with red shards (combination of transparent and opaque), the other blue and the third green. I was delighted with the outcome. The second workshop was scheduled just in time for Thanksgiving and the pumpkin blowing instructor duo (Jarrod and Gavin) was outstanding! The students were taught to work with molten glass to create a hollow glass bulb, pattern ridges on the tube, add two different colors (of their choice). Finally, the students were taught to fuse a stem (slender piece of molten glass, also with ridges and of a third color or irridiscence of the students' choosing) onto the pumpkin, twist and curl the stem into a spiral, and securely glue it onto the hot pumpkin body. This was a phenomenal class with significant complexity and a variety of techniques to learn and demonstrate. [In the interest of full disclosure, I did attend a third Valentine's day vase blowing class at BAGI, that was, frankly, quite a bit disappointing; I am leaving that experience out for the purpose of this review, considering it an outlier by BAGI standards (likely they were just having a bad day), and for the sake of otherwise giving BAGI a 5/5 review.]
