Artsy California Cob Oven with Benches in Sacramento

Date(s) - Sunday, June 28, 2020 - Sunday, July 5, 2020



The Artsy California Cob Oven & Benches workshop will be located at Nico and his wife’s place in Sacramento, CA.

More info to come shortly on the location and hosts as we have recently changed the site to their place!  This workshop will be in an urban setting and students can camp or stay indoors unless they live locally.



Professional baker’s oven built in Puerto Rico by CCG instructor Viva Hansen and local students.


We will be building a community-size cob oven for baking everything in. Students will build the foundation, insulation, and three oven shells (inner, insulation, outer) and finish with plaster.  The high heat-exposed cob is different than the building cob used for the benches and external sculpted shell and students will learn the difference and how to figure out each mix.  The oven and benches will allow for maximum creativity that will depend on the students’ input and inspiration!  All materials will be as local as possible and students will be building all phases with lecture time to support the hands-on work.

The 7-day workshop will begin on Sunday evening, June 28, with dinner at 6pm, followed by an Opening Circle, Introduction to the Site and the Workshop.  Monday morning June 29th at 9am we begin building the foundation. There will be hands-on building for 4 hours in the morning followed by lunch and rest for 1.5 hours. At 2:30pm there will be a 30-60-minute lecture followed by construction in the afternoon.  Students will have time to relax in the afternoon and go to the river or on a walk or into town if they like before dinner.  There may be someone in the group offering to lead yoga or chi gong movement practice also. The workshop will end on Sunday July 5th after breakfast and July 4th there will be a BIG CELEBRATION and DINNER….of course!

Forming the sand dome in Portugal


The first day of the workshop will be building the foundation out of local rock, broken concrete or even tires. Day 2 we will build the support for the oven as well as the form and inner cob shell.  On Day 3 we will focus on the benches so the oven can dry.  We will be building the foundations and covering them with cob.  Day 4 we will empty the oven (if ready to be emptied), and cover it with the insulation layer in the morning and the final sculpting cob layer in the afternoon.  On day 5 we will sculpt and build other additions to the area which will be decided on by students and host, like a small stove or grill or other useful cob embellishments. On Day 6, everything will be plastered.  And, if the sand is out, we may even be able to light it and make pizza to celebrate Independence Day!!!  On the final Sunday morning we will have a Closing Circle after Breakfast and the workshop will end with a Goodbye Lunch!



Students will need to come prepared for physical labor from Day 1.

This includes:

Work clothes appropriate for the country and climate we are in
Work boots or other closed-toe shoes (for foundation work)
Flip-flops (for cob days)
Rubber dishwashing gloves (for lime mortar for foundation)
Work Gloves (for carrying rocks)                                                                                            
4”-6” Diameter Round Plastic Container Lids (for plastering)
Good Moisturizer
Water Bottle
Sample of Your Soil (Optional)

Please get the excellent cob oven bible by Kiko Denzer called “Build Your Own Earth Oven”…noone has written a better one yet. Amazon has it of course… as do others.  There are many inspiring pictures and it will prepare you well for what’s to come.

Students need to tend to their needs like making sure they drink alot of water (clay is drying), get good sleep and stretch before and after class.  This class is not very demanding physically compared to the building workshops but if you are not used to doing any physical work with earth, sand, rocks….you should definitely prepare yourself in the weeks ahead by resting well, stretching, and even carrying rocks around properly.  Also feel free to share your dietary needs (not preferences) with CCG and bring your special snacks and foods, pillow and whatever you NEED to be comfortable and happy. We also encourage you to bring slides, videos, movies and books to share, as well as a sample of your soil to test. And we always play diverse music onsite while we build, so bring your favorite playlists!



Students without a personal vehicle or not carpooling (we will organize a carpooling list a month before the start date) can take a bus (Greyhound/Trailways) or train or even fly into Sacramento. Students can also fly into San Francisco.  Usually all students can get rides from other students to the site from their home base (if in driveable distance) or from the closest city or town along the way.



Chocolate Mousse must have been good, Marla!!!

Students will be fed 3 high-quality delicious meals a day during the weekdays prepared by experienced cooks.  CruzinCobGlobal hosts always serve amazing food to cob students in gratitude for their hard work! Since this is California there is no lack of amazing vegetarian food, which will be the basis of our menu.  Students that have non-vegetarian requirements can bring personal items to complete their diet and other requirements can be presented to the cooks a month before the start date so they can make sure to have what is needed.  We will try to meet people’s requirements of course so it is important to communicate them as soon as possible.

Students will be camping onsite or staying indoors in a shared space.
