Glass can melt at lower temperatures than low fire clay fires. You can melt you glass into molds at lower tempertures depending on the composition of the glass. Just like different ingredients affect the melting point in low fire and stoneware glazes, the composition of the glass you are using will have different melting points.
Does your kiln have a temp set or do you use cones to visibly trip the off release? Is it an Amaco?
Yes, drill the hole to help the glass release. Make sure you have fireproof gloves and good tongs. Keep your hair pulled back and covered and wear long sleeves....no synthetics.
You will need good protection to remove the molten glass from the kiln to "droop" it over a bowl. Have you been there when your friend has done hers? Observing technique is valuable.
Since your lid has electric coils, you will want to be careful setting that lid back and reaching into the kiln to get your glass. 14-1800 degrees can cause some serious burns. The quick change in temperatures over time can cause some damage to your coils...so close your lid once your glass is removed. This helps equalize the temperature of the coils on the lid with the retained heat in the rest of the kiln.
Do you have an asbestos pad to set your mold on so you can close your kiln? If not, might be a good time to have another person there to assist you the first several times you practice. If you mold is big enough you could set it on an 8 x 8 x 16 cinder block that is turned so the openings are up.
The close your lid and then droop the soft glass over the shape you are using.
If you are making flat tiles, those can be melted in the kiln on the shelves and allowed to cool just like doing a load of clay. Once cooled, the glass can be tapped off the shelf or out of the mold and brushed. Score and cut the glass the grind the edges.
