Mark is collaborating with FOCI Glass in Minneapolis, MN

to create hand-blown drinking glasses

 using our kiln-formed cookies


cookie molds


Mark starts with metal molds

and fills them with glass chunks, stringers and rods

 The cookies are placed in the kiln

and heated to 1500 degrees F  


ready to be blown out


The completed cookies will be taken to the hot-shop

where gaffers will blow them into drinking glasses



 Check back to see the gaffers at work...

Thank you to FOCI gaffers Michael Boyd, David Royce,

and Andrew Thompson for their participation in this project.

FOCI Glass Cup Sale,

a Springboard for the Arts fundraiser



This project was completed earlier in the year...


Mark has just started work on a fused / leaded chapel window for the

Benedictine Living Community in Saint Peter, MN.

Mark began with a full-scale color sketch.

He is now creating the fused pieces to incorporate into the window.

We ran into some difficulty with this project when a power outage struck mid-firing in the middle of the night. We lost two complete panels, but it allowed us to see how we could make changes that would improve the appearance of the window.

Panel Ready to Fire in Kiln




















We're back on track now, and the project is progressing well. The pre-fused elements (eagle, angel, etc) are set in place on the panels. The background (trees, water, etc) are now being added in the form of powdered and ground glass and some torched pieces.

Adding Backgrounds to Panels


















 All of the panels have been successfully fired in the kiln. 

We've leaded the panels together to complete the window.

It is now ready to be transported to the site and installed.
