This set of wall mounted tubes looks like they could be meant for a smoke or playing a tune which is highlighted in my YouTube video What's It 4?. There are multiple layers of colored slips and terra sigillata and fired in my flex fuel recykiln with a soda vapor atmosphere. Ready to hang on an appropriate wall for all to see. Please understand due the complexity of this work I will need to charge for shipping as it will be double boxed when shipped. This cost will be arranged with the purchaser via email.
