This is yet another area where terminology gets a little mixed up. In my own
teaching and practice I have always considered a liquid clay decorating or
coating mixture a slip if it is made for application to wet or leather-hard
greenware. I have considered such a mixture an engobe if it is made for
application to bone-dry or bisqued ware. Some people refer to all slips as
engobes, but that doesn't sit well with me. So, according to the terminology
as I use it, commercial underglazes are engobes, in that they may usually be
applied to bone-dry or bisqued wares.
I shouldn't presume to speak for the list moderators, so the following is my
own slant on the issue of asking questions on Clayart. Don't appologize for
asking any kind of question on this list. As someone else said in a post some
time ago, "stupid question" is an oxymoron. The only thing stupid is to not
ask the question at all, or to chastise someone for asking a question which
seems simple or common. It is true that some people take up excessive list
space asking questions that could be so easily answered in any ceramics text,
but yours is not one of them. So, continue to ask questions for everyone's
sake.

Vince,
How are the two mixtures different? I have an oxide and clay mixture I use
as either a slip or engobe without any problems (that I'm aware of!).
Thanks for your help.
