    Glaze on bonsai pot foot

    Hi guys, I am just starting with pottery and glazes, finding it extremely interesting. In the past weeks I built a couple of bonsai pots, 2 of them being bisque fired. Stoneware was used. Next step in my journey is to glaze them. I bought 2 brush-on glazes and in the following days I want to start the work. My questions are the following: 1. I know that I am not supposed to glaze the pot foots because the glaze will stick to the kiln. I should apply wax resist on the entire foot or just on the part that will actually sit on the kiln? I saw pots that have the foots glazed, the lateral parts. How can this be achieved? Attached you will find an example. 2. The kiln owner is high-firing only for me because he usually is low firing kids items, so the cost is pretty high for me as I have to pay for the whole kiln every time. If I will glaze the 2 pots now, can I keep them safe and fire them in 2-3 weeks when I will have a couple of other pots made so I can pay for the whole kiln and have several items fired? Is there any issue if I'm firing glazed pots for the second time and bone dry for bisque fire, everything works at same temperature of 1.280 C? Thank you. Vlad

    Long story short, 2 weeks ago I went to the kiln owner for bisque firing and after he discussed with the kiln manufacturer, he decided to fire my stoneware directly to 1,280 Celsius with a slow heating curve. On the clay it was indicated to be fired at 1,150 - 1,280 Celsius. At that point I didn't knew what I know today. Yesterday I applied high-fire glaze which is indicated to be fired at 1,200 - 1,240 Celsius on these 2 items and the glaze stayed in place very well. I don't understand how this happened as everybody is telling me that my clay has been vitrified and will not accept the glaze. The kiln owner confirmed again today that he bisque fired my items at 1,280 Celsius. Today the kiln owner fired my glazed 2 items to 1,200 Celsius, hopefully tomorrow he will get back to the shop and call me to come pick them up. Let's see tomorrow or on Saturday how it went.

    When I am having a glaze that should be fired to a lower temperature than the one at my clay matures, can I bisque fire at the clay maturing temperature, and after that glaze it and fired to a lower temperature? @neilestrick is saying that because I fired at 1,280 C, as was indicated for my clay, now it is vitrified and it cannot be glazed, as it is not porous. But my glaze is on the pot, in 4 coats and looks great. I will try to fire it tomorrow and see what is happening.

    So when it writes on my stoneware clay 1,280 C, it means that I can bisque fire to a lower temperature and after I glaze, I should fire at 1,280 C? My glazes are for high temperature, one is for 1,200 - 1,240 C and one for cone5, that means around 1,050 C if I remember correctly. I glazed both my pots and the glaze stays very well on the pots. Should I have any firing issues? Thank you.

    The pots I want to glaze are bisque fired. As this is the first time using these glazes, I don't know if are runny or not, I will find out soon. Thank you for the idea of how to glaze the foots. In terms of design, it might look better for my pots to leave the foots unglazed. I will think about it. The stoneware clay I have is recommended to be fired at 1,280 C and my glazes at the same temperature. So the temperature is the same but I don't know if the heating curve of the kiln can be the same if I will fire 2 pots for glazing and another 2 pots for bisque. This way it will be more cost effective.
