“ …We don’t have a complete answer for what the ‘best practices’ are for this sort of outdoor work. One thing we do have data to back up, and which we already discussed during my BECon talk in 2011, is the idea of symmetrical construction: placing the “design layers” of glass between solid layers of clear glass of equal thickness. However, our testing was limited to panels whose thickness was only 1/2” thick. How does that principle scale to outdoor pieces that are 2”, 3”, 4" thick? We don’t know.”
Nine years ago I had decided I wanted to make works of corten-steel and cast Bullseye glass. The work I had made in cast glass went from about 6 inches thick to 3 inches thick tapering to a 1/4 inch thick edge. Basically the cast glass piece is a 24 inch disc with a 6 inch sphere that intersects the disc at the bottom where it is attached to the corten steel structure like a gemstone is attached to the bezel of a ring. I had made three castings, two in clear Bullseye and one in Neo-Lavender Shift Bullseye with corten steel that sold to a collector in Boston. I still have the Clear Bullseye and corten steel piece in my garden after nine years and one can imagine the temperature changes that the glass has gone through in the Rochester, New York area.
Temperatures here in the Northeast vary from 100 degrees F in summer to minus 9 degrees F in winter in open space with no sun or wind shelter. Often temperatures are drastic in difference in the period of a single day. I had made this experiment years ago to address for myself the question raised in the Forum as to whether Bullseye glass could work well or not in harsh climates. I can say that it does withstand harsh climates perfectly. I think one needs to consider the design though.
One might ask themselves a question or two. Does the glass have recesses or negative spaces where water can collect? If so then you can predict that the water will freeze in those areas. Water when freezing is expanding and contracting and could cause undue stress on the glass. My next experiment would be to make a water basin where water could collect an freeze and thaw. I suspect it would work fine if the transition from thick to thin areas of the glass is gradual.
I have heard no complaint from the landscape architect in Boston who had bought my work for his coastal retreat, the work in my yard still stands up to the elements as does the orphan clear glass casting set on a stone wall outside my studio, still waiting for a corten structure to elevate it.
