Services
From the sand to the installed tool.
We work across the whole quartz chain — feedstock, fusion, forming, fabrication, specification, qualification and installation. Most clients need us at one point in it. A few need us at all of them.
Service 01
Material selection & specification
The decision between fused natural quartz and synthetic fused silica is made once and lived with for years. We work it properly: the real thermal and chemical environment, the contamination budget, the hydroxyl target, the mechanical duty, and the cost of the part over its service life rather than at the purchase order.
The output is a specification a supplier can be held to — measured properties, test methods, acceptance limits and incoming inspection criteria — not a trade name and a hope.
- Grade selection with written technical justification
- Purity, OH, bubble class and homogeneity limits
- Dimensional schemes and tolerance strategy
- Test methods, certification requirements and incoming inspection
- Review and repair of existing specifications
Service 02
Sourcing & supplier qualification
Quartz supply is more concentrated than most buyers realise. Commercially viable high-purity quartz deposits exist in only a handful of places worldwide, the number of refiners able to reach semiconductor grade is smaller, and the producers of synthetic boule can be counted on two hands. A tier-two single point of failure is common and rarely mapped.
We audit suppliers on the things that predict performance — fusion route, furnace control, annealing practice, metrology, traceability and change control — and we help establish a credible second source before it is needed rather than during a shortage.
- Technical supplier audit and qualification
- Feedstock provenance and supply-chain mapping
- Second-source strategy and risk assessment
- Commercial and lead-time benchmarking
- Support during quotation, sampling and first-article approval
Service 03
Boule, ingot & tube engineering
For clients who make the material rather than buy it, we work on the production problem directly: deposition and fusion control, annealing schedules and residual stress, striae and homogeneity, coring and slicing yield, tube drawing dimensional control, and flame working practice.
The recurring theme is that a large fraction of finished-part defects are created after the glass is good — in annealing, in machining, in flame working and in cleaning. We look at the whole route rather than only the melt.
- Fusion and deposition process review
- Annealing, stress and homogeneity improvement
- Tube drawing: wall uniformity, ovality, straightness
- Machining, subsurface damage and finishing practice
- Cleaning, etching and packaging integrity
- Yield improvement and scrap reduction
Service 04
Failure & contamination investigation
Quartz parts fail in a small number of characteristic ways, and each points somewhere specific. Devitrification points at surface contamination, alkali or handling. Sag points at hydroxyl and temperature profile. Bubble growth points at the melt interface and the fusion route. Particles point at fabrication and cleaning. Metallic contamination points at the base material or the tooling that touched it.
We work backwards from the symptom to the cause, then write the specification or process change that stops it recurring — which is usually the part clients actually needed.
- Devitrification, creep and sag investigation
- Particle and contamination source tracing
- Premature part-life root cause analysis
- Cleaning and handling protocol review
- Corrective specification and process changes
Service 05
Fab development & installation
Building a quartz fabrication line, or a facility that consumes quartz at volume, is a mechanical and facilities project as much as a materials one. We support layout, utilities, equipment selection, installation, commissioning, acceptance and the ramp that follows.
This work is led by principals who have installed and started up production equipment for four decades — which mostly means anticipating the problems that only appear during install.
- Facility layout and process flow planning
- Utilities: gas, power, cooling, exhaust and abatement
- Equipment installation and commissioning
- Safety review and compliance support
- Start-up, qualification and production ramp
Service 06
Equipment, training & technology transfer
Fusion furnaces, drawing towers, glass lathes, CNC finishing and metrology — specified, evaluated, commissioned and accepted. And then the part that determines whether any of it works: training the engineers and operators who will run it every day.
Technology transfer engagements are structured to leave capability behind. We write the process documentation, train against it, and measure whether the training took.
- Equipment specification, evaluation and vendor selection
- Acceptance testing and commissioning
- Operator and engineer training programmes
- Process documentation and work instructions
- Structured technology transfer and capability build
Working together
How an engagement runs.
Initial conversation
A call to understand the problem and the constraints. No charge, and no obligation. If we are not the right people for it, we will say so and, where we can, point you at who is.
Scope & proposal
A written scope: the question to be answered, the work required, who leads it, the deliverable, the timeline and the fee. Confidentiality agreed before any technical detail changes hands.
Investigation
Document and data review, site visits where useful, supplier discussions, and analysis. We work with your engineers rather than around them.
Findings & recommendation
A written report with the reasoning shown, not just the conclusion — so your team can challenge it, and can apply the same reasoning next time without us.
Implementation support
Optional and often the most valuable part: supplier discussions, specification rewrites, qualification trials, installation and training through to a working result.
Engagement formats
Short technical opinions, defined projects with a fixed scope, retained advisory arrangements, and longer technology-transfer or installation programmes. Remote or on-site.
Independence
We do not sell material, hold inventory, or take commission from suppliers. Our recommendation on a grade or a vendor is the one we believe — which is the entire reason to bring in an outside opinion.
Start with the problem, not the service.
Describe what is happening. We will tell you whether it is a material question, a fabrication question, or a process question — and whether we are the right people for it.
