Colour Chart for CIM

[Sam]

Just wondering if anyone knows where I'd get a colour chart showing the characteristics for CIM glass?


Also how do I strike glass



Many Thanks,



Sam

Hi Sam,

Click here to download a CiM colour chart.
Or take a look at the Off-Mandrel.com CiM page, which is almost as good. 

I posted this about striking a while ago, it should help:

"Striking is always accomplished via a cycle of heating and cooling. Whether that is rapid or slow, in the flame or in the kiln, through a large or a small heat differential, are all dependent on the glass and the effect you require.
For example, Iris Orange (Raku) is said to be best struck by heating to hothothot, then cooling as fast as possible.
Effetre striking red, orange, yellow will strike by heating until clear, allowing to cool, and then warming gently by wafting in the back of the flame. (although the reason for the colour change is a bit different in  these than in silver glasses)
Ditto with CiM strikers, and indeed this is a good process to use when approaching any unknown but supposedly striking glass.
Many silver glasses respond well to repeated warming and cooling cycles, moving through a range of colours and effects, often returning to their starting colour, where the process can be repeated a few times (depending on the glass) until the silver is 'burned out'.
Some (like TAG Jupiter, discussed above) are very easy to overstrike, and need only the whiffiest whiff of hot air in the back of the torch to colour up after the heat/cool cycle.
Some (eg TAG Black Cherry) are designed to strike very slowly in the kiln at around annealing temp allowing very good hue control, and so will overstrike instantly in the flame.
Experimentation with any new striking glass is always necessary, as setup, conditions and working style will affect the outcome. You can use the experience of others as a starting point, but it is never a guarantee of success in replication of results.

Check Hayleys (enVisions) blog for lots more about silver glass, with ebooks on the subject and everything."

HTH,
