Are Crown Lynn for Barbara's cups and saucers E/W or vitrified?

I see an auction matching white tulips with "Barbaras" saucers:

I expect Crown Lynn for Barbaras to be vitrified: Can anyone help here?

I guess I've answered this for myself now.
From my study of web pics of CL for Barbara's I see that the cups and saucers are earthenware, a combination of 3066 Honey Cup and 4062 Classique saucer.

Crown Lynn did pair these two shapes elsewhere, for example in "Homestyle" d74600.

I have a teal "for Barbara's" saucer and both cup and saucer shapes in clear glaze.

There is no evidence of either of these being made as vitrified shapes.

I'm asking the same question Jeremy, as this casserole for Barbara's on the Portage site is a 5634. Perhaps because it is a casserole .... I would guess so.
The only other piece that shows up on the Portage site is a saucer and they have given it the number 805 ...

I have a Barbara's butter dish and boy it feels like it is vitrified to me. I can't even find a number for it as these were made around the time that the records finished and this one has a rimmed edge and is 14cm. If anyone can offer some ideas please do as I would appreciate some help.

I think it must be a mix, some e/w shapes, some vit.
Which could be interesting wrt pattern numbers.

The casseroles must be vit. The teapots I can't be sure and I should be because I looked at Jim's one last week.

(Btw, there is or has been a Topaz teapot on tm with a vit number and I thought Topaz teapots were e/w.)

The saucer at Portage is too big for an 805 and is more likely a 4062.

Edit.
Teapot for Barbara:

This should be a 1220. I can't find the posting for 1220.

Re trademe teapot. Seller says 1616 but shows badly crazed lid. That should not be.

Teapot.
After forgetting I'd done so before I asked seller about teapot (unless it is a totally different one) and it is numbered 1616. Crazing is a mystery. It may be in the nature of the Barbara's glaze to craze or it could be crush damage, which can look like crazing.

Thanks for heading me in the right direction Jeremy as I found what my shape is ...
4049 sugar lid for 3042, 5023 or coaster now 8040 on ram press

So it isn't vitrified then and you would be correct that some things like casseroles will be and if the Barbara's cup is a 3066 then the saucer is a 4062 like you suggested.

Photos and this is such an odd colour.  Would one call it Puce?
