There's some unsound harm reduction advice given in this thread.
Licking a butter knife is a really bad thing to do if you value your teeth and may even make you prone to mouth infections.
If you take base orally and wish to minimise the damage done, then dissolve it first in a glass of water. Anything that doesn't dissolve with a bit of stirring is not base anyway so why eat it? Left over solvent and/ or impurities from the synth are what comprise the insoluble parts. If dissolved properly, the amount that sticks to the glass is negligible. You can use warm water if you find it doesn't dissolve, but I don't recommend it as some of the undesirable impurities will become more soluble in hotter water.
Wrapping a piece in a cig paper may ensure all of it gets to the stomach, but it will also cause the speed to be concentrated in one place which can cause stomach upsets and ulcers long term. If there are carcinogens or nasty toxins present the effect could be worse long term.
In regards to tryfound's comment; if you've got pure or next to pure meth (ice) for Gods sake listen to Splatt's advice. If you're heart set on IVing it, I'd suggest no more than a 10th of the dose you mentioned.
Also be careful with Ural or any alkaliser. Alkalisers work by changing urinary pH which means some things normally excreted are retained for longer and vise vera. With a drug like meth that produces toxic metabolites, this increases plasma levels of both meth and most of it's metabolites. Yes it can extend the effects, but because less meth is eliminated unchanged, the level of toxic or possibly toxic metabolites is increased as much of the normally eliminated meth will continue to pass through the liver.
Don't think that because a bit is good, lots must be great. While the body can compensate for relatively large changes in acidity (lower pH), by comparison, buffers present in the blood cannot do the same with significant increases in alkalinity (higher pH). Ural should be avoided if you've been vomiting and/or are susceptible to hypernatraemia, have any history of cardiac failure or kidney disease (in which case you shouldn't be taking meth anyway), if you're taking quinolone antibiotics and hexamine mandelate or hexamine hippurate which can be prescribed for a number of conditions.
