It produces glassy results that are nice (but only for certain models).
The idea behind this is to increase the amount of protein you can apply in a single go. A typical
soya drink has about 3 grams of protein per 100 millilitres. This is useful to produce thin double paper, but sometimes you need a bulkier paper. You have a similar problem if you use
Egg-white protein powder . This is rich in protein, but the solubility is limited, so you end up with the same problem as with the soya drink. The solution: dissolve the egg-white protein powder in soy the soy drink.
The upside: it produces a beautiful glassy paper. Probably nice for flowers.
The downside: This paper is difficult to use if you need many folds.
TIP 1: You can use three sheets of tissue paper instead of two and use either egg-while powder or soya.
TIP 2: Use unsweetened soy drinks.
TIP 3: Use starches instead of proteins.
How to use it
Dissolve a table-spoon of egg-white power in a quarter (or less) of soya drink. Shake it until the powder dissolves.
Paint the surface with the mixture. Sometimes you can skip this step, as the liquid will permeate the paper.
Lay two sheets of tissue paper one on top of the other.
Paint them with the mixture.
Where to buy?
In the UK from Tesco, any supermarket. 1 litre of unsweetened soya cost £0.55. The four sachets (4 x 5 grams) of egg-white cost about £1.2 in Tesco; however, if you use a lot, you will be better of buying in in bulk from Amazon (for example) where 500 grams costs around £13 (500 grams of MC cost around £22).
