Terra, our original striking color. Hand pulled rods came out in an opaque rainbow with multiple rings in the core. When pulled by hand, a hot punty is dipped into the furnace, the glass is marvered, reheated in a glory hole, and the process is repeated until we have a big enough gather to pull across the shop. All that super heating and chilling builds up layers of pre-struck glass.
Reset, cool and strike. Anneal at a low temperature to avoid unwanted kiln striking.
