Before the enthusiasts of the chapel veil question get all revved up, this is about chalice veils and burses, which are designed to hold the corporal when during Mass it is not in use upon the altar.
From a reader:
Do you know where suitably appropriate burses and veils can be bought
for a good price? I want to buy some for our parish as a thank you to
our priest before I go to University.
A nice gesture.
I know that many chasubles these days are sold without veils and burses – horribile dictu. I hope that trend is changing. In the Ordinary Form, use of the chalice veil is not absolutely required, but it is strongly recommended, or it was in the older GIRM. Newer, 2000 GIRM? I didn’t find it. I believe there is also profound symbolism in the moment of the unveiling of the chalice. Also, in the Ordinary Form white can be used as a chalice veil on all occasions.
Also, the burse has a practical use, especially for those who believe in the Real Presence. The corporal is traditionally folded in such a way that, when closed up again at the end of Mass, any particles of the Host that may have been missed by the priest will stay within the folds and not simply be scattered. The burse holds the folded corporal so that it won’t unfold.
I suppose that any Catholic religious goods store, online or in non-virtual reality, would be able to help you find chalice veils and burses. Also, veils would not be especially hard to make.
UPDATE 22:57 GMT:
A commentator added this useful citation, below:
New GIRM 2000: Sorry it is late in the evening, and I cannot be bothered to look up a translation, so am using the altar Missal which is near my desk. You will be glad to know the veil is indeed mentioned.
Caput IV : De Diversis formis Missa celebranda, part entitled Praeparanda :
Section 118, last paragraph: “Calix laudabiliter cooperiatur vela, quod potest esse aut coloris diei aut coloris alba.” So there you have it. (trans “it is good to cover the chalice with a pall, [No. Vela is "veil", not pall.] which may match the vestments, or white)
The earlier para of the same section also expects the chalice pall if you have one: “c) in abaco: calix, corporale, purificatorium et, pro opportunitate, palla.” No mention is made of the Burse, so very oddly.
