At the sign in desk, you may or may not have noticed a new sign with a QR code on it. A QR code looks like the example on the left. Now you can simply scan the QR code using your Smart Phone and once you have entered your details it will register your attendance. At the end of the pottery session click the ‘Check out’ button on your Smart Phone and you’re signed out. Next time you sign in scan the QR code and your attendance will be automatically recorded.
If you haven’t already – don’t forget to join the club!
Remember you need to be a member of our club to use the facilities and have first access to join the workshops.
Being Respectful, Feeling Safe
The club’s Code of Conduct was written to guide the safety and respect of members. Developing friendships, being co-operative, sharing ideas and skills and being respectful to each other in words and actions is something in which the club takes great pride. When members are working in the SPC Inc studio or interacting with other members via electronic means, everyone has a right to feel safe and not harrassed.
The Code of Conduct can be found in your membership documentation or you can request a copy from the Membership Officer here or you can read it here.
How Does Vinegar Bind Clay?
To create a join in your clay construction that is stronger than water or slip alone – try using white vinegar. Since clay is slightly alkaline, the acidity of vinegar makes it act like a glue for clay. Apply it to both surfaces and press the pieces directly together without slipping or scoring. The acidity of the vinegar breaks down the clay a bit, and makes it sticky. Some artists use vinegar straight from the bottle, or add vinegar to clay (instead of water) to make a joining slip. You will find the vinegar in the studio on the shelf near the sink area. Magic in a bottle!
And now for a very technical answer:
Vinegar is used in clay bodies to increase acidity to improve plasticity. The acid works to neutralize sodium ions (from water, leaching feldspars) that tend to deflocculate the clay. However, excessive acid may tend to dissolve more feldspar or nepheline syenite negating the effect.
(A-ha, now I only need to know what deflocculate means – Editor)
