Terms and Conditions

Booking & Cancellation Policy

Please note: all accepted changes to workshop or class bookings may incur an administration fee.

Weekly Classes

Your booking fee secures your place, payable via our website or by bank transfer. We cannot reserve places without payment. Your booking is only confirmed once a 50% deposit or payment in full has been received.

If we cancel or alter the time or location of a class, you will be offered a full refund or the option to transfer to another available class.

One-Day Workshops

Full payment is required to secure your place. We cannot reserve places without payment.

Martin will always try to move you to another date if you can no longer attend (subject to availability). If a transfer isn’t possible, the following refunds apply:

• Cancelled more than 4 weeks before: 90% refund
• Cancelled 1–4 weeks before: 50% refund
• Cancelled 7 days or less before: no refund

All cancellations incur a 10% administration fee. To keep prices fair for everyone, this policy applies without exception.

If we cancel a workshop for any reason, you will be entitled to a full refund.

Group & Bespoke Bookings

A 50% deposit is required to confirm a group booking, with the remaining balance due one month before the workshop date. Group bookings are subject to a minimum number of participants, agreed at the time of booking.

Individual places within a group booking will not be refunded — your total booking cost is based on the original agreed number of participants.

If you cancel more than one month before the workshop, a 50% refund will be offered. Cancellations made less than one month before the workshop date are non-refundable. If we cancel or alter the content, time, or location of a workshop, you will be offered a full refund or the opportunity to rearrange.

All refunds and booking changes are at the discretion of Martin McAssey Glass.

Tools, Equipment & Safety

Working with stained glass involves specialist tools, materials, and processes that require care and attention. The safety of our students is our highest priority.

Before participating in any workshop or class, all students are required to read and sign a safety agreement. Tool use is only permitted following a full induction led by an experienced tutor. All equipment is regularly inspected and maintained.

Tools & Equipment

You will have access to a range of stained glass tools and equipment during your session, including:

• Glass cutters, running pliers, and breaking pliers
• Glass grinder
• Lead came and lead came knives/cutters
• Soldering iron and solder
• Light table
• Fid, horseshoe nails, and glazing tools

Chemical Hazards

The following materials and substances are used during stained glass work:

• Lead came — lead dust may be produced during cutting; full precautions are in place
• Soldering flux (oleic acid or zinc chloride based) — used to prepare surfaces for soldering
• Chemical patina/darkener (e.g. copper sulphate solution) — used to finish and age solder lines
• Glass cleaning solutions
• Putty or glazing compound (for panel strengthening)

We follow all current health and safety guidelines for working with lead and flux fumes. Thorough handwashing is required before eating, drinking, or leaving the studio.

Personal Protective Equipment

All required personal protective equipment is provided, including safety glasses, protective gloves, and aprons. Adequate ventilation is maintained throughout all sessions. Students are expected to use all provided PPE at all times during practical work.

You are responsible for your own conduct and personal safety while using our studio facilities. Martin McAssey Glass holds full public and professional liability insurance.
