Welcome to the Online MIT Great Glass Pumpkin Patch

This year’s fundraising event will be taking place both in-person and online.

Starting in September 2020 a small group of masked senior instructors were granted access to the Glass Lab for the purpose of blowing 2000 glass pumpkins for the iconic event, with half being available for the in-person event and half available on this site ( 

Pumpkins will be available for online purchase Saturday, September 25th from 10 AM - 6 PM (EST).

The in-person event (held in the heart of MIT campus on Kresge Oval) details:

Opening Preview: Friday September 24th, from 5 - 8 PM (no sales). 

Sale: September 25th from 10 AM - 3 PM.

When will pumpkins be available online?

Saturday September 25th 10 AM - 6 PM

At 10 AM approximately 1000 pumpkins will appear in the catalog on the top of this page.  Prior to that we will be posting select images of this year’s pumpkins at:

In the meantime please familiarize yourself with this site and enjoy pictures from previous Great Glass Pumpkin Patches.

How this will work?

 All pumpkins will have a listed sale price as they do at the in-person sale on Kresge Oval. This is not an auction.  All of the pumpkins are one-of-a-kind, so there is only one of each item. The size of each pumpkin can be approximated by comparison with a ruler that appears in each photograph next to each pumpkin. All of the pumpkins will be released for sale at the same time, at the start of the sale. All sales are first-come-first-served; pumpkins will become unavailable when a payment transaction for that pumpkin has been completed.

Shipping: All pumpkins will be shipped via FedEx Ground from MIT. The cost of shipping will be added to the sale price of the pumpkin(s) you buy. Due to the complexity and expense of overseas shipping, we regret that we must limit shipping to the Continental United States.

Return policy: Consistent with our live sale policy, there are no returns on pumpkins except in the case of a serious structural defect such as a crack or very sharp surface. Please shop thoughtfully and carefully. In the unfortunate event that your pumpkin should arrive defective or broken, we will replace it free of charge with one as similar in size, color and shape, as possible.

Question: How has the pandemic changed the process of blowing glass at the MIT Glass Lab?

Answer: Team based, hands-on activities at MIT have been seriously challenged by the COVID pandemic. This was certainly true for the MIT Glass Lab where students work in close proximity learning the ancient craft.  Many practices long considered normal, such as sharing blowpipes, were suddenly off-limits.  Upon return to the Glass Lab we immediately developed a new blowing system that allows a fully masked glass blower to use compressed air controlled by a pneumatic foot pedal to stop and start inflation. 

We are a self-funding program. 100% of our annual operating revenue each year comes from the sale of glass pumpkins and from gifts, large and small, made by generous donors.

The MIT Glass Lab is dedicated to offering memorable hands-on experiences for MIT students, faculty and staff, as well as public lectures and events like the MIT Great Glass Pumpkin Patch, that are open to the MIT community and the general public.

Please consider making a donation to help us continue to provide these opportunities. Gifts to the Glass Lab can be made via the MIT Alumni Association at this link:
