坩埚的存放
错误的做法：坩埚一个叠一个的放在水泥地面上；坩埚在存储或运输的过程中受潮。
Wrong practice：
正确的做法：坩埚应该存储在干燥的地方，最好是放在木托盘上；坩埚倒过来放的时候可以重叠放置。
Right practice：The crucible should be stored in a dry place, it is best to put on the wooden pallet; the crucible can be overlapped when upside down.
1.坩埚必须储存在干燥的环境中，最好是放在木托盘上，并保持通风；The crucible must be stored in a dry environment, it is best to put on the wooden pallet, and maintain ventilation;
2.坩埚倒过来放的时候可以重叠放置；When the crucible is turned upside down, it can overlap;
3.切忌坩埚不能暴露在潮湿的环境中，否则吸潮后的坩埚，釉层很容易在坩埚预热环节中剥落，从而降低坩埚的熔炼效率和使用寿命，情况严重时甚至会出现底部脱落。
The crucible cannot be exposed to the humid environment, after absorbing the crucible, the glaze layer is easy to be peeled off in the preheating section of the crucible, so as to reduce the melting efficiency and the service life of the crucible, and even the bottom can fall off when the situation is serious.
燃气炉、生物颗粒炉、燃油炉、焦炭炉、煤炉坩埚的安装
Gas stove, bio-particle furnace, oil furnace, coke oven, coal furnace crucible installation
错误的做法：在支撑砖和坩埚之间留下的空隙太小，坩埚膨胀受阻会裂开。
Wrong practice：The space left between the support brick and the crucible is too small, the crucible expansion will be blocked will crack.
正确的做法：在支撑砖和坩埚之间插入小木片，木片会燃烧掉从而留下足够的空隙。
Right practice：Insert a small piece of wood between the support brick and the crucible, and the wood burns away to leave enough clearance.
错误的做法：炉子顶部没有完全密封，坩埚顶部容易受到氧气氧化，从而产生竖直裂纹。
Wrong practice：The top of the furnace is not completely sealed, and the top of the crucible is susceptible to oxygen oxidation, resulting in a vertical crack.
