Colour de Verre


This is a new mold from the Colour de Verre glass which includes a 5 and a 6 point snowflake that should be filled with 5 to 9 grams of fine frit respectively.  This wont be easy to measure out but i will try.  In an attempt to not overdo I underdid, I think and the result was pretty but fragile and it broke.  So I am trying it a second time, this time carefully filling each space without overflowing on the top.  I also tried to mix blue with clear fine frit and I increased the firing schedule as follows:

300 dph..................................1280 degrees............................hold 10 mins
FULL.......................................900  degrees............................hold 30 mins OFF.

This is called the "Snowy" Casting schedule in opposed to the "Icy" casting schedule.  And now I just read that I should have increased the temperature by 15 degrees for COE 90 glass.  This will teach me to read all the directions in the future.



So it worked one, 5 point, one six point and neither has broken,  They are still very fragile, I am going to add then to sheets of glass, 3 3/4" by  3  3/4" square and then slump them.
