Frequently Asked Questions

Please be aware that during this workshop we will be working with lead, acids, and other corrosive materials.
Lead Warning and Prop 65. https://www.p65warnings.ca.gov/fact-sheets/lead-and-lead-compounds
Lead is on the Proposition 65 list because it can cause birth defects or other reproductive harm. Exposure to lead during pregnancy can affect brain development and cause learning and behavior problems for the child. Exposure to lead can harm the reproductive systems of men and women.
Traditional leaded panes or Tiffany copper foil— lead is a key component is stained glass. No matter the technique, we use lead to solder the seams and hold our glass together. While there are lead-free solder alternatives, we will use leaded solder in class. Why lead?
PPE: We will Provide gloves, disposable face masks, and proper ventilation. If you’d like to bring in a respirator for flux fumes, make sure it is rated for VAPOR. With Proper PPE the risks for lead poisoning are small. If you have any health concerns please reach out to your health provider.
We know life happens! But our classes are intentionally small, our instructors are paid by enrollment, and materials are prepped ahead — so please make sure you can commit before booking. Here's how it works:
Single day Workshops
Cancellations made 14 days or more before class are eligible for a full refund or class credit.
Cancellations made less than 14 days before class are no longer eligible for refunds but can apply credit towards a future class.
Cancellations made less than 48 hours before class or no-shows are not eligible for a refund, credit, or rescheduling.
If we ever have to cancel a class, you'll get the choice of a full 100% refund or 100% class credit.
Multi-week courses
Non-refundable, but can be rescheduled or transferred or to a friend or within a year of booking.
Please don't sign up if you already know you'll miss multiple weeks. In general, missing one class is okay, two is a little hairy.
We don't offer make-up classes. If you miss a regular week or feel behind, you're welcome to join us for Open Studio at the current student rate.
Each week we learn a new skill that builds toward your finished project. Some skills are easy to catch up on. Others, like soldering, are critical and take a whole class session to teach. Missing a critical skills week may mean you can't finish your project without private instruction. Private instruction depends on instructor availability and you'll need to make it up with an instructor at our private rate ($15 every 10 minutes, $90 an hour).
If we ever have to cancel a class, you'll get the choice of a full 100% refund or 100% class credit.
Participants must be at least 13 years old unless otherwise noted in the class description. Anyone under 18 must be accompanied by a participating (registered and paid) guardian.
Any seat can be transferred once to another person — just email us their name before class.
Gifting a class and don’t know when they’ll attend? No worries, choose the gift card option or email Kristin at kristin@glassspectrum.com and we'll set you up.
Good tools are an investment. We believe when you invest in your tools you invest in your hobby. Students get 10% off Beginner Kits and select tools. We take pride in our selection and can verify the authenticity of everything we carry. Every tool, material, and sheet of glass in our shop is chosen for quality and durability — we know, because we use them every day.
Shopping small keeps studios like ours in business. Thank you for your support!
