Ricky Harrison
manages UGA’s
glass-blowing shop, a unit of the Office of Research Services
that is located in room 337 of the chemistry building.
He explained the shop’s mission and procedures for
Columns.
Columns: What do you do?
Harrison: We fabricate, modify and repair a variety
of standard and custom, one-of-a-kind scientific glassware
for the UGA research community. Often we can make commercial-type
glassware that saves UGA researchers time and money. Right
now Brian Markowicz (a glass blower III) is making standard
condensers used in distilling to supply Campus Scientific
Stores. It takes 30 to 45 minutes to make a condenser and
costs $38, which is about half the price of a commercial supplier.
We make repairs on-site for things such as vacuum lines, to
reduce the chance of leaks, and for equipment that’s
fixed or too large to transport. We also offer a pick-up service.
Columns: How long has UGA offered
glass-blowing services?
Harrison: Howard Epperson started the shop in 1960
and he ran it until he retired in 1984. He came to UGA from
Oak Ridge National Laboratory. I started as an apprentice
under Howard in 1975. I was out of high school and looking
for a career.
Columns: What’s the most
unusual glass-blowing project you’ve worked on?
Harrison: That’s a tough one, because the departments
that request our help are all so different. Some of the simplest
things can be amazingly hard. For one research project we
made specialized rat feeders. The researchers brought us a
commercial feeder and wanted it duplicated. They weighed the
bottles before and after each feeding so they wanted them
to be as close as possible to the same weight.
There are many different kinds of glassware needs and it’s
rewarding to know your work is contributing to new knowledge.
Columns: What are the hardest
kinds of projects?
Harrison: Usually it’s when we do multiple “jackets”—or
seals—on glass that has multiple ports. It’s hard
to keep the glass from cracking, especially if it’s
real thick. You have to heat the glass and that puts stress
on it; sometimes when you’re almost done, it cracks
and you have to start all over. It also can make you nervous
to be working on a glass piece that might cost $5,000 and
you’re trying to repair it. We tell the customer that
there’s a chance the equipment can break when we heat
it to a high temperature. We have to keep glass hot until
we’re finished and then we have to cool it down gradually
in an oven. Since it’s already broken, most of the time
it’s no good to the researchers like it is, so they’re
usually willing to take the risk. We could be saving them
a lot of money if we can fix it.
Columns: What’s the biggest
frustration?
Harrison: A bad day when things aren’t going
right. You work hard on a project and it cracks and you have
to start over.
Columns: What’s the range
of time projects can take?
Harrison: Anywhere from 15 minutes for a small job
to two weeks for one with multiple components. On big projects
you have to stage your work so you’re at a quitting
point at the end of the day.
Columns: What’s the biggest
advantage of having glass-blowing capabilities on campus?
Harrison: The ability for researchers to get glassware
for their exact needs and specifications. Researchers can
talk to us about what they need and we can design and blow
glassware equipment for special applications with a quick
turnaround and at a reasonable cost.
Columns: Do most research universities
offer glass-blowing services?
Harrison: Many do. Some of the smaller schools used
to but don’t any more. In some universities glass blowers
work for the chemistry department, but we work for the whole
university. We also do projects for other universities, federal
agencies such as the EPA, and private companies such as Noramco,
a pharmaceutical branch of Johnson and Johnson. We charge
by the hour and projects outside the university are billed
at a higher rate.
Columns: How many people work
at the shop?
Harrison: There are three of us. Brian Markowicz has
a glass- blowing degree from Salem College in New Jersey.
It’s the only school in the country that teaches scientific
glass blowing as far as we know. Patricia Kelley is the senior
accounting assistant.
