The bees will draw it, but much slower than foundation and much much slower than foundationless. The sheets when poured and not pressed (like foundation is pressed) are very tough and hard for the bees to work with plus they don't resemble comb. Since they will build foundationless faster and it is much less work, I would do foundationless...
But that's not what some researchers have found. A preference was shown by the bees for drawing comb on 'thin non-embossed sheets' over 'thick non-embossed sheets' or 'embossed foundation'.
Interestingly, the comb mid-rib was always the same thickness regardless of the thickness of the wax sheet the bees started with - demonstrating that wax can be (and often is) easily re-cycled within the hive.
Regret I can't post a link to these results as the powers that be won't let me (not enough posts) - and I've been threatened with expulsion if I circumvent the prohibition notice in any way ...
But - if anyone feels suitably motivated ...
Take yourself off to the beesfordevelopment dot org site, then do a site search for 'low cost foundation' by Aidoo and Paxton. The same search terms entered into Google will also return that document, which is a .pdf file.
Hope you find it of interest.
