Register for the 2023 Mystery Metals Challenge and Group Exhibition! 

We are back with another exciting event that will challenge you to make use of materials supplied by our sponsor, Rio Grande! 

That's right! The secret supply kits have returned, but there is a limited number available so don’t miss out!

As always, this is a Members Only Event. Make sure your dues are paid up for the year if you want to participate. 

New This Year: Teams! Sometimes two heads are better than one, and this year we want to open up the challenge to those who'd like to collaborate with another member! You must register as a Team up front and include the names of both team members on your registration form. The decision to register as either an Individual or Team will be final at the time the entry fee is paid. The same rules that apply to individual participants will also apply to the teams. Only one kit will be supplied to a team, with the advantage being two minds and up to 4 hands working on one entry collaboratively. 

Registration is open now through 11:59pm Pacific Time April 30th, 2023. (All sales are final as of April 30th, 2023)

Mystery Supply Kits with this year's rules and parameters will be shipped out to all registered participants on May 1st. 

Finished pieces are due by August 31st.

The challenge culminates in a 2-week group gallery exhibition at Chemers Gallery in Tustin, CA with an opening scheduled on the evening of Saturday, October 7th, 2023.

All entries must be priced and available for sale. Proceeds from all sales are split 50/50 between the artist and the gallery.
