Calcined lead and tin
What?!?! You can not calcine lead or tine as they will melt. I will leave a bit before removing to allow the author to correct.

Hard vs. Soft Paste Porcelain
I see that an older version of this article contained an explanation of soft- versus hard-paste porcelain, which read:

Without supplies of kaolin, the porcelain was not true porcelain, but what is termed "soft-paste porcelain", composed of white clay, white sand, powdered quartz, and calcined lead and tin. The result is translucent like true porcelain but slightly glassy in feel, owing to its fused silica content. The glaze fuses with the body in the kiln, as with true, or "hard paste" porcelain.

It looks like User:217.42.216.152 found this to be confusing or misleading, but I think that it's very useful for readers to know what qualities distinguish one type from another; perhaps we could find a way to put this information back in? If User:217.42.216.152 (or someone) would like to suggest an edit that is less questionable, that would be great and - I think - improve this article. Thanks!
