Erase vs. Glyph of Warding placed in a Hall

Greeting all
I have a question about the Erase Spell(pg. 279 PF Main Core)

If the Glyph is Not on a paper or Paper like surface will erase remove it??? and does this leave either Disable device or Dispel magic as your only choice?
The surface in question is a stone floor.
any advise will help here

I mean only way to disable it.
I think that because the Erase spell clearly states Paper, Parchment or similar surfaces a Glyph placed on a stone Floor is unaffected by the spell. would I be correct?

That would be correct within the Rules as Written. On the other hand, it may be an unintentional restriction of the spell - it seems that the intent was for it to also be useful against sigil-style traps, which are hardly ever put on a paper surface (barring Japanese-style paper walls/doors in your dungeon.) I'd say that the GM would be well-justified in regarding the "paper" reference as a guideline to the maximum square footage that can be erased rather than the materials that can be targeted.

Ok I could see that but Glyph of Warding has two Targets effects one is Item Touched or up to a 5ft square/level.

If I use the Paper reference I still would not be able to effect the whole glyph cast at Min. level unless the spell is placed on a smaller than 5ft square.

Target line is what matters here. Spell targets the surface, not the ward/glyph/sigil. Spell can't touch chalk on a wall either.

Well considering a glyph of warding would not usually be placed on a piece of paper, I think the wording for erase is just a bit off.

Glyph of Warding:
This powerful inscription harms those who enter, pass, or open the warded area or object. A glyph of warding can guard a bridge or passage, ward a portal, trap a chest or box, and so on.

You set all of the conditions of the ward. Typically, any creature entering the warded area or opening the warded object without speaking a password (which you set when casting the spell) is subject to the magic it stores. Alternatively or in addition to a password trigger, glyphs can be set according to physical characteristics (such as height or weight) or creature type, subtype, or kind. Glyphs can also be set with respect to good, evil, law, or chaos, or to pass those of your religion. They cannot be set according to class, HD, or level. Glyphs respond to invisible creatures normally but are not triggered by those who travel past them ethereally. Multiple glyphs cannot be cast on the same area. However, if a cabinet has three different drawers, each can be separately warded.

It is intended as a trap on a portal that can be passed through or an object that can be opened. Reading does not set off a glyph, so putting it on paper wouldn't do anything (unless it is some sort of origami you could open up).

So Let me see if I understand correctly.
You could Place a Glyph of Warding on a Cover page of a book to trigger when opened or on an envelope or sealed scroll and Erase will remove it on a successful Caster level test because it this form the area effect is within the limits of the spell.
but if the Glyph is on a larger area like a 10x20 section of hallway The Erase spell has no effect.

would this be a correct under standing?
If So can we get a FAQ on this please or an errata on the wording because it is a little confusing.

Anyone??

I think the key question is what is meant by "similar surfaces".

It looks like a case of GM fiat to me.

I agree. "Similar Surfaces" opens it up to much GM interpretation.

For exmaple:
Is chalk on stone similar to ink on paper?
How about ink on vellum?

The important part with GM fiat is to try to be consistent with the decisions. It will save much sanity later!

But the Target section of the spell description states one scroll or 2 pages.

where as Glyph of warding states "When casting the spell, you weave a tracery of faintly glowing lines around the warding sigil. A glyph can be placed to conform to any shape up to the limitations of your total square footage. When the spell is completed, the glyph and tracery become nearly invisible. Glyphs cannot be affected or bypassed by such means as physical or magical probing, though they can be dispelled. Mislead, polymorph, and nondetection (and similar magical effects) can fool a glyph, though nonmagical disguises and the like can’t. Read magic allows you to identify a glyph of warding with a DC 13 Knowledge (arcana) check. Identifying the glyph does not discharge it and allows you to know the basic nature of the glyph (version, type of damage caused, what spell is stored)." p.291 PFCR
and Glyph's target line reads object touched or 5 sq.ft/per level of caster
if the area is larger that 2 pages or one scroll I think that the spell have no effect on the glyph.
