Ambrose Quillfeather-Nwachukwu

Scientific Glassblower
Corning, NY, United States

Professional Summary

Scientific glassblower with 15 years of experience designing, fabricating, and repairing precision borosilicate and fused quartz apparatus for research chemistry, physics, and materials labs. Builds custom vacuum manifolds, Schlenk lines, and glass-to-metal seals on the lathe and at the bench, cutting researcher wait times and replacement spend. Known for clean annealing practice, polariscope-verified stress-free work, and a 98% on-time repair record across 60+ research groups.

Employment History

Senior Scientific Glassblower
Finger Lakes University — Department of Chemistry Glass Shop · Ithaca, NY
Jun, 2019 · Present
Design and fabricate 120+ custom borosilicate and fused quartz pieces per year for 60+ research groups, including vacuum manifolds, Schlenk lines, and photoreactor vessels. Built 18 dual-manifold Schlenk lines with high-vacuum PTFE valves, saving the department ~$54,000 versus catalog purchases. Cut average repair turnaround from 9 business days to 3 by introducing a triage queue and pre-stocked joint and stopcock inventory. Fabricate graded glass-to-metal (Kovar and tungsten) seals and quartz-to-Pyrex transitions for UHV and spectroscopy setups with zero field leaks in 2024–2025. Program and maintain annealing ovens and polariscope inspection; trained 40+ graduate students yearly in glassware safety and handling.
Scientific Glassblower
Chemung Valley Lab Glass Co. · Elmira, NY
Jul, 2014 · May, 2019
Produced 1,500+ standard and custom lab glassware units annually on Litton and Heathway glass lathes to ±0.2 mm tolerance. Fabricated fused quartz reactor tubes and boats for semiconductor customers, growing quartz line revenue 35% over three years. Reduced breakage scrap from 7% to 2.5% by standardizing anneal schedules and polariscope stress checks on every order. Quoted and built 200+ custom vacuum manifolds and distillation assemblies from customer CAD sketches with a 97% first-fit rate. Mentored 3 apprentices and wrote 25 shop SOPs covering lathe setup, flame safety, and grinding.
Apprentice Glassblower
Southern Tier Optics & Glassworks · Corning, NY
Jun, 2011 · Jun, 2014
Completed a 6,000-hour apprenticeship in bench and lathe glassworking, graded seals, and precision grinding. Fabricated 400+ optical cell, cuvette, and Dewar components under senior glassblowers with less than 1% rework. Ran kiln and annealing oven loads and logged thermal profiles for 100% of shipped parts. Repaired 300+ broken flasks, condensers, and stopcocks, saving customers an estimated $40,000 in replacement cost.
