Playing with Clay and Glass - 1st Jun 2013

On the 25th of May I had the pleasure to share my studio with an awesome extended family group consisting of 4 adults and 4 teenagers.

As an introduction to casting glass, we made models from clay and used the open method of casting glass. We removed the clay as soon as the plaster molds were set, but before the clay goes hard. 

Working with small flattish forms we could fire them in 5 days allowing for the molds to be opened the following Saturday.  There was great excitement to see the results and range of colours.

We had such a great time that this group is coming back again in a couple of months...meanwhile here are some comments from the group;

"I found the glass course was actually really fun, as well as challenging it really got in touch with my creative side, playing around with ideas. The glass course itself was challenging, but a good challenge, and I really enjoyed it and I love my glass pieces and I can’t wait to do it again."
Shani aged 16

"I really liked Di because she wasn’t grumpy, she was friendly and she helped me when I needed help. When I didn’t like my clay I was allowed to scrunch into a ball and make it again. I loved doing the workshop as a whole family and my glass pieces are awesome."
Mila aged 12

"It was an amazing experience for me, and everyone too. You helped me and guided me, thanks for that."
Kaya aged 14

"It was so cool making glass. Di was really nice and helped me when I couldn't think of an idea. We got to pick the glass colours we wanted to use. Now we have our creations at home and get to look at them when ever we want!"
Jonty. Aged 14

If anyone is looking for a great family or team event this is the one for you.
We found regardless of age and ability everyone had a fantastic time and created some amazing glass. Half the fun was seeing the joy that everyone had collectively. Di is awesome!
Donna, Rosina, Nadine and Kelli (adults)

Making Rubber Molds - a fun challenge - 26th Feb 2013

Students who recently undertook Di Tocker's Rubber Mold Making Course had a lot to think about about over the 2.5 days in her studio.  Rubber molds can be a challenging task.  Each student made their own rubber mold from a personal object. 

The six who attended came from various backgrounds including some who have done previous workshops with Di, some who have learned cast glass with other tutors and a bronze caster.

Rubber Molds - useful tools

Di says "Rubber molds are a very useful tool in the casting studio.  They will last for 100's of wax pours, can be very accurate with detail or serve as a 'blank' for creating base wax forms to slightly alter with each use".  To create this accuracy a complicated process to produce the mold is required.  All six students produced successful molds which they can now take home to work with.

Workshop Participant - Comments

"The process is a complex one and we most definitely needed the two-and-a-half days to complete our molds. Di demonstrated every step and provided us with comprehensive written instructions, which will be invaluable for future reference. The group was also small enough that Di could observe what everyone was doing and provide help to those who were having difficulty"

"I really liked seeing everyone else’s work, I learn just as much by seeing other people push their ideas as I do by pushing my own.  The best thing is, my mind is once again buzzing with ideas and I cannot wait to do the next course.  Thanks for everything Di. You’re a fantastic and patient teacher and that is perfect for me".

"I have attended several courses over the years and found Di's teaching technique to be the best I've experienced. She is not only an extremely accomplished glass artist, but she is happy to share her knowledge and has the patience required to cope with different levels of experience".
